TD Merchant Solutions

Platform / Acquirer

B-

TD Merchant Solutions is the merchant-services arm of TD Bank, N.A., the Cherry Hill, New Jersey bank that operates as 'America's Most Convenient Bank' from Maine to Florida and is owned by Toronto-Dominion Bank. Like most US bank merchant programs it is built on Fiserv: the hardware is Clover, the gateway third-party reviewers identify is Fiserv's Payeezy, and the Clover trademark disclosure on TD's own page names First Data. Like its bank peers it publishes flat rates, and its in-person rate is the lowest headline figure among the big-bank programs we cover. As of September 2026 the small-business page quotes 2.5% + $0.15 for swiped, tapped and chip transactions and 3.5% + $0.15 for keyed, phone and e-commerce payments, with customised pricing available through its Payment Advisors, and it promises funds in a TD settlement account by 6 AM ET the next business day. The catch is the contract. The current offer — a free Clover Go, terminal or Clover station worth $179 to $1,025 — requires a three-year Merchant Solutions processing agreement and an active TD business checking account, and TD's own footnote says an account terminated before the end of that term will be charged the value of the device, solution or credit it received. Third-party reviewers additionally report a $495 early-termination fee and $19.95-a-month PCI and gateway charges that TD does not publish. The bank behind it is also mid-remediation: TD Bank, N.A. pleaded guilty in October 2024 to Bank Secrecy Act and money-laundering conspiracy charges, paid about $3.09 billion in penalties and accepted a cap on its US assets. That does not touch card processing, but it is the counterparty on the merchant agreement.

Polar

Merchant of Record

B-

Polar (polar.sh) is an open-source merchant of record and billing platform for developers selling software, SaaS subscriptions and digital products. It is run by Polar Software, Inc., a Delaware corporation whose team is based in Stockholm, and was founded in 2022 by Birk Jernström, who co-founded the e-commerce platform Tictail, sold it to Shopify in 2018 and then led product for Shopify's Shop app. Polar launched version 1.0 of its billing platform in September 2024 and raised a $10 million seed round led by Accel in June 2025, with angels from Shopify, Vercel, Supabase, Raycast, Resend and Framer. As merchant of record it is the legal seller of everything sold through it — it collects and remits US sales tax, EU VAT, Canadian GST and other taxes, carries chargeback liability and issues the invoices — and it charges a single platform fee on top of that. That fee changed on 27 May 2026. Organisations created before that date keep an 'Early Member' rate of 4% + 40¢ plus 0.5% on subscriptions indefinitely; new organisations pay 5% + 50¢ on the free Starter plan or buy down the rate with Pro ($20 a month, 3.8% + 40¢), Growth ($100, 3.6% + 35¢) or Scale ($400, 3.4% + 30¢). International (non-US) cards add 1.5%, disputes cost $15 each regardless of outcome, payouts go through Stripe Connect at Stripe's pass-through fees ($2 per active payout month, 0.25% + 25¢ per payout), and organisations created on or after 12 May 2026 have a seven-day settlement delay before they can withdraw. Its code is Apache 2.0 on GitHub, its SDKs and framework adapters are widely praised, and its weak points are the ones you would expect of a seed-stage company two years into operating: thin support, fixed dunning you cannot customise, and pricing for newcomers that is now level with Paddle and Lemon Squeezy rather than below them.

Paystone

ISO

B

Paystone is a London, Ontario payment processor that calls itself Canada's largest bank-independent payment processor. It was founded in 2009 as Zomaron by Tarique Al-Ansari, who remains chief executive, rebranded to Paystone in November 2019 when it bought the Montreal gift-card and loyalty company DataCandy, and has since grown by acquisition — NiceJob in 2021, Canadian Payment Services in 2022 and the TSXV-listed loyalty firm Ackroo, for about C$21 million, in 2025 — on the back of roughly C$99 million raised in 2021, including C$30 million (about US$23.8 million) from Crédit Mutuel Equity. Its website says it serves more than 38,000 business locations and processes over $10 billion a year. The offer is interchange-plus with published starting points: in-person credit from 1.26% + 5¢ and debit from 5¢ a transaction on a $5-a-month merchant account, online credit from 2.27% + 25¢ on a $15-a-month gateway, a $99 setup fee, no locked-in contract, no cancellation fee and next-business-day deposits. Terminals range from the Ingenico Desk/5000 and Move/5000 to Clover Flex, Mini and Station Duo, and the processing is sold alongside its own DataCandy gift and loyalty programs and NiceJob review software. It is a registered MSP/ISO of U.S. Bank's Canadian branch and Elavon and of Wells Fargo Bank's US and Canadian branches, and a partner of Global Payments Direct and First Data Canada. The complaint record is small — third-party review sites count a handful of BBB complaints, mostly about terminal-rental billing and cancellation timing — and the company's BBB profile is currently under review. 'As low as' pricing means the real rate is a quote.

ProMerchant

Agent Office / Reseller

B-

ProMerchant is a small merchant-services company in Woburn, Massachusetts, started in May 2018, that sells card acceptance to US restaurants, retailers, mobile traders, phone-order and e-commerce businesses, and places harder-to-approve merchants — CBD, vape, supplements, firearms, credit repair, telemarketing and dozens of others on its published list — with what it says are twelve different high-risk processors. Its pitch is the terms rather than the rate: month-to-month agreements with no early-termination fee, no setup or application fee, a free terminal placement programme, and a choice between interchange-plus pricing with a fixed markup and a zero-cost surcharge plan for retail and restaurant merchants. It publishes no numbers; third-party reviewers report quotes starting around interchange plus 0.50% and $0.15 per transaction and $0.30 per virtual-terminal transaction. Funding is next day for batches settled by 8:30pm Eastern and otherwise two business days. It holds an A+ from the Better Business Bureau, accredited since November 2018 with seven complaints in three years, and a 4.3 on Trustpilot from 258 reviews — though only a couple of those are from the last year, and a run of mid-2024 reviews describe months of unanswered calls that ProMerchant attributed to a restructuring at a parent company unrelated to payments. With about 15 staff and no disclosed sponsor bank or processor, it is an agent office: your contract, reserve and funding terms come from whichever processor it places you with.

Barclaycard Payments

Platform / Acquirer

B-

Barclaycard Payments is the merchant-acquiring arm of Barclays Bank PLC, the business that has signed UK shops up to take cards since Barclaycard launched the country's first credit card on 29 June 1966 and installed the UK's first electronic point-of-sale terminal in 1986. It is one of the largest acquirers in the UK — the company says it processed more than nine billion card payments in 2025 for more than 160,000 businesses, settling in 18 currencies and accepting 118 — and it is in the middle of the biggest change in its history: in April 2025 Barclays agreed a partnership under which Brookfield Asset Management will help run the business as a standalone company, Barclays will put in about £400 million, and Brookfield can buy a majority stake from year three. A new chief executive, Jason Lalor, formerly of Mastercard, Conferma and Square, started in January 2026. For merchants the offer splits in two. Small businesses get Smartpay Anywhere, a £29 + VAT pocket reader with no contract and no monthly fee, or Smartpay Touch, a £29 + VAT-a-month Android terminal on a 12-month term with no exit fee; both settle next working day for sales taken before 7pm. Traditional countertop and portable terminals come on 18-month contracts at £16 or £18 + VAT a month after a free first year, with an exit fee if you leave early. Barclaycard publishes no rate card — every account is priced on turnover, with representative examples of 0.7% + 3p on an in-person debit card and 2.05% + 3p on a keyed credit card — and its service reputation is the weak point: the only Trustpilot profile blends consumer-card and merchant reviews and is dominated by complaints about reaching a person.

Tyro

Platform / Acquirer

B+

Tyro Payments Limited is a Sydney-based merchant acquirer and bank, founded in 2003, granted a specialist credit card institution licence in 2005 and a full Australian banking licence in 2015, and listed on the ASX as TYR since 2019. It serves more than 77,800 Australian merchants, processed $44.3 billion in transaction value in the year to June 2026, and reported gross profit of $231.8 million, EBITDA of $66.9 million and statutory profit before tax of $22.3 million for that year. Its pricing is published and flat: 1.3% including GST on every card transaction for businesses under $20,000 a month, a custom quote above that, and a Pro Touch or Pro Key terminal at $29 a month, a Pro Lite at $19, or a Tap to Pay app on your own phone for nothing — with no lock-in contract, no joining fee and no break fee. New customers transacting more than $20,000 a month who join before 24 November 2026 get 1% until 31 March 2027. Takings settle seven days a week, the same day, into a fee-free Tyro Transaction Account protected by the Financial Claims Scheme, or next business day to an outside bank. Tyro integrates with more than 580 POS and practice-management systems, routes debit through the cheapest network with Tap & Save, and lends up to $400,000 against card takings. The record has one scar: a January 2021 terminal outage that left some merchants unable to take cards for weeks and produced a Federal Court class action that Tyro settled in principle in February 2023 without admitting liability. Nigel Lee became chief executive in January 2026, and Tyro's Australian Trustpilot profile is 4.2 from about 560 reviews, 69% five-star and 20% one-star.

Flywire

Platform / Acquirer

B

Flywire is a Boston-headquartered payments platform, incorporated in July 2009 as peerTransfer to move international tuition money and renamed Flywire in 2016, that now collects large, often cross-border receivables for about 5,300 clients in education, healthcare, travel and B2B — more than 3,300 educational institutions, more than 150 healthcare systems and roughly 1,800 travel and business clients. It listed on Nasdaq as FLYW in May 2021, processed $37.6 billion in total payment volume in 2025 on revenue of $623 million and net income of $13.5 million, and has bought its way into new verticals: Simplee (healthcare, 2020), WPM (UK universities, 2021), Cohort Go (2022), StudyLink (Australian admissions, 2023), Invoiced (B2B receivables, 2024) and Sertifi (hotel payments, $330 million, February 2025). Clients sign negotiated agreements and Flywire publishes no rate card; its revenue is a percentage of each payment that varies by payment method, currency pair and region, plus fixed fees on domestic transactions, and the payer sees the total, including any Flywire fee and the currency conversion, before confirming. Its subsidiary Flywire Global Corp. holds money-transmitter licences in 46 US jurisdictions. Two things temper the picture: a securities class action, Hickman v. Flywire, has been pending in the Eastern District of New York since July 2025 over how the company described the effect of student-visa policy on its growth, and Flywire has voluntarily reported apparent sanctions violations to OFAC after an internal review. Its Trustpilot score is 4.0 from about 3,150 reviews, mostly written by students and patients paying through it rather than the institutions that choose it.

Teya

Platform / Acquirer

B

Teya is a London-headquartered payments and business-banking company founded in 2019 as SaltPay by Ali Mazanderani and Eduardo Pontes, renamed in April 2023, and backed by investors including Tiger Global, Ribbit Capital and Michael Spencer — total funding is reported at about $845 million by data providers and $1.1 billion by The Business of Payments. It grew by acquisition — Iceland's Borgun in 2020, the UK's RMS Group in 2022 and the Czech ePOS company Storyous among them — and now sells to small businesses in nine European markets, the UK, Croatia, Czechia, Hungary, Iceland, Italy, Portugal, Slovakia and Spain, with Spain and Italy launched commercially in February 2026. In the UK the offer is a Teya Pro or Teya Lite card machine from £14.99 a month with a lifetime warranty, Tap to Pay on iPhone and Android, online payments, and a free e-money Business Account that card takings settle into next working day as standard, every day including weekends and bank holidays as an option, or in seconds with Instant Settlements. Rates are quoted rather than published — the pricing page says there is no standard price list, the card-machine page says fees start at 1.59% — and using an outside bank account instead of Teya's adds 0.10% to every transaction. Teya Solutions Ltd is an electronic money institution authorised by the Financial Conduct Authority (reference 978181), so the account is safeguarded rather than FSCS-protected. Its UK Trustpilot profile is 4.4 from about 1,500 reviews, 82% five-star and 15% one-star, and the one-star reviews are about held funds and unreturned calls.

myPOS

Platform / Acquirer

B

myPOS is a London-headquartered payments company founded in 2012 by Christo Georgiev and owned since February 2024 by the private-equity firm Advent International in a deal reported at around €500 million, after which the founder exited and Mario Shiliashki, formerly of Mastercard and PayPal, became chief executive. It sells card machines outright — the myPOS Go 2 at £39, Flex at £59, Go Combo at £169 and Ultra at £179, all excluding VAT — with no monthly fee, and settles every card payment instantly into a free myPOS e-money business account with a Mastercard business card, a model it says it pioneered in 2014. The UK rate card is published for businesses under £10,000 a month: 1.10% + 7p on domestic consumer cards, 2.20% + 7p on EEA consumer cards, 2.45% + 7p on American Express and 2.85% + 7p on everything else in person, and 1.30% + 15p domestic, 2.50% + 15p Amex and 2.90% + 15p other cards online; larger businesses get a custom quote. UK, Gibraltar and Swiss services are provided by myPOS Payments Ltd, an electronic money institution authorised by the Financial Conduct Authority (reference 900826), and the group says it serves more than 400,000 merchants in over 30 countries with 15 physical stores, up from the 170,000 small businesses Reuters reported when the sale was agreed. Its Trustpilot profile is 4.2 from nearly 22,000 reviews, 70% five-star and 13% one-star, and the one-star reviews are about unexplained application rejections, slow deliveries and support that is hard to reach.

CDGcommerce

ISO

B+

CDGcommerce is a family-owned merchant services provider founded in 1998 by Chris and Laura West and based in Port Orange, Florida, operating as a registered ISO/MSP of Pinnacle Bank (dba Synovus Bank) and Citizens Bank, N.A. It is unusual among independent sales organisations for publishing its entire rate card: a flat-rate plan at 2.90% + $0.30 in person and 3.50% + $0.30 online with a $9.95 monthly fee, an interchange-plus plan at interchange + 0.30% + $0.10 retail, + 0.35% + $0.15 online and + 0.25% + $0.10 for non-profits, and a wholesale membership at $49 to $199 a month paid annually with per-transaction cents from 15¢ down to 6¢. Its own Quantum gateway and virtual terminal are free, there are no PCI, annual, statement or gateway fees, and — in the company's words — in more than twenty years it has never required a contract length or termination fee. It holds an A+ rating and BBB accreditation since 2020 with two complaints closed in three years, and it makes no attempt to serve merchants outside the United States or in adult, cannabis or telemarketing categories. The weaknesses are the ones that come with a small shop: a thin self-service knowledge base, a Dejavoo terminal that carries a $79-a-year update charge, and third-party reports of funding holds and terminations on riskier accounts.

Zeller

Platform / Acquirer

B+

Zeller is a Melbourne payments and business-banking company founded in 2020 by Ben Pfisterer, who had led Square's Asia-Pacific team, and Dominic Yap, and launched in May 2021. It sells an EFTPOS terminal outright — the Zeller Terminal 1x and the newer Zeller Terminal 2, both listed at A$99 on promotion in September 2026 — with no monthly rental, no lock-in contract and a flat 1.4% on every in-person card, American Express included, falling to 1.2% when payments run through its free Zeller POS software. Every merchant gets a Zeller Transaction Account and debit card at no cost, with card takings settled into it nightly and available the next business day at an outside bank. It also offers invoices, a virtual terminal, Tap to Pay on iPhone and Android, corporate expense cards and, from April 2026, a UK operation priced at 1.3% on domestic Visa and Mastercard. The company reached a valuation above A$1 billion ten months after launch on the back of a A$100 million Series B in March 2022 and says more than 100,000 Australian businesses use it. Zeller Australia Pty Ltd holds an Australian financial services licence and is a principal member of Mastercard; merchant funds are held in a segregated account at Cuscal rather than in a bank deposit. The pricing is among the simplest in the Australian market and the hardware is well regarded; the recurring complaint is the one every fintech acquirer attracts — funds frozen pending documents, with slow answers.

Wix Payments

Payfac / Aggregator

B-

Wix Payments is the native payment processor inside Wix, the website builder founded in Tel Aviv in 2006 by Avishai Abrahami, Nadav Abrahami and Giora Kaplan and listed on Nasdaq since 2013. It lets a Wix merchant accept cards, Apple Pay, Google Pay, PayPal and instalment plans from Affirm, Afterpay and Klarna without connecting a third-party processor, with payments, payouts, refunds and disputes managed from the Wix dashboard. Wix's own help centre says it is available in fifteen countries and, in its terms, that the processing underneath is handled by Adyen and Stripe in most regions and by Pagar.me in Brazil — so this is a payment facilitator layered on other acquirers rather than a new one. US pricing is published in full: 2.9% plus 30¢ on standard cards online, 3.7% plus 30¢ on American Express, 2.6% flat on the Wix POS hardware, 2.6% plus 20¢ for Tap to Pay, 3.5% plus 30¢ keyed, 6% plus 30¢ on the instalment options, a 1.5% cross-border surcharge and a $15 chargeback fee. Payouts run daily, weekly or monthly and reach a US bank in three to five business days after a two-to-five-day pending period. The case for it is one dashboard, a competitive in-person rate and a real hardware line; the case against is that online it costs exactly what Stripe charges directly, Amex is expensive, Wix's documented reserve and hold policy gives it wide latitude over your money, and support is chat and callback only.

LawPay (8am, formerly AffiniPay)

ISO

B+

LawPay is the payment processor built for law firms by AffiniPay, the Austin, Texas company Amy Porter founded in 2005 and which rebranded its corporate identity as 8am in August 2025; the product now trades as 8am LawPay. Launched in 2007, it is offered through all fifty state bar associations and more than sixty local and specialty bars, describes itself as the only ABA-recommended payment solution for the legal industry, and says more than 120,000 lawyers use it. Its reason for existing is trust accounting: card fees are debited from the firm's operating account rather than the client trust or IOLTA account, and chargebacks and refunds cannot be pulled from trust funds, which is what the bar rules require and what a general-purpose processor cannot promise. Pricing is published in full and interchange-free: $19 a month with no contract, 2.99% plus 30¢ on Visa, Mastercard and Discover, 3.90% plus 30¢ on American Express, 1% on eCheck, 5.95% on its Pay Later legal-fee financing, plus a $7.99 monthly card-brand pass-through fee and 1.75% on foreign cards. Since January 2024 eligible firms have had next-business-day funding on cards and eCheck, and since April 2026 8am has guaranteed it. 8am, LLC operates as an independent sales organization of Fifth Third Bank, Wells Fargo Bank, Synovus Bank and Fiserv Canada. The record is good: an A+ BBB rating with fourteen complaints in three years, and a Trustpilot profile that is 78% five-star. The costs are a card rate a tenth of a point above Stripe's, an Amex rate near four percent, and a pass-through fee that reviewers say catches firms unawares.

Squarespace Payments

Payfac / Aggregator

B-

Squarespace Payments is the native payment processor inside Squarespace, the New York website builder founded by Anthony Casalena in 2003 and taken private by Permira in October 2024 for about $7.2bn. Announced in October 2023 and rolled out first in the United States, it now covers fifteen countries and lets a Squarespace merchant accept cards, ACH, Klarna, Afterpay and other methods without connecting Stripe or PayPal, with payments, payouts, refunds and disputes managed inside the Squarespace dashboard. Underneath, Squarespace's own help documentation describes Stripe as its processing services partner, so this is a payment facilitator layered on Stripe rather than a new acquirer. US pricing is published in full: 2.9% plus 30¢ on standard cards on the Basic and Core plans, 2.7% on Plus and 2.5% on Advanced, a 1.5% surcharge on international cards, 3.2% plus 30¢ on American Express and premium cards, ACH at 1% to 1.5%, and a $20 dispute fee. Payouts are daily and reach a US bank account in one to two business days. The case for it is convenience and, on the higher plans, a modest rate cut; the case against is that it is no cheaper than Stripe direct on the plans most merchants are on, it is locked to Squarespace, and a steady stream of complaints describes risk holds on funds with no phone number to call.

Dojo

Platform / Acquirer

B

Dojo is the trading name of Paymentsense Limited, a London company incorporated in 2008 that grew into one of the UK's largest card-terminal resellers before rebuilding itself, from 2020, as a cloud-native acquirer under the Dojo brand. It now holds its own acquiring licence rather than reselling Fiserv's, and by its own filings handled £46.2bn of card volume for roughly 146,000 merchant locations in the year to March 2025 — a share it puts at 12.5% of UK small-business card-present acquiring. The pitch is simple: a fast card machine, money in your account the next day including weekends and bank holidays, integration with more than 450 EPOS systems, and a UK phone line. For businesses turning over less than £100,000 a year on cards there is a published Fix plan at £39.99 a month covering the first £3,999 of monthly card turnover, with 1% above that. Everyone larger gets a quote. Independent satisfaction is strong — 4.2 on Trustpilot from 5,612 reviews, 88% of them five-star — and the company is FCA-authorised. Against that sit a 12-month minimum term with the remaining terminal fees payable if you leave early, custom pricing that cannot be benchmarked, a fee schedule with £28 chargebacks and a £15-a-month PCI non-compliance charge, and a balance sheet carrying £649m of net debt at a 14% effective interest rate.

Viva.com

Payfac / Aggregator

B

Viva.com is a European payments company and licensed bank, headquartered in Athens, that sells card acceptance, a business account, cards and financing to small and medium businesses on one platform. It is unusual in two ways that matter to anyone comparing processors. The first is disclosure: where almost every acquirer in Europe quotes privately, Viva.com publishes a full price pack per country — acquiring rate, scheme pass-throughs, plan fees, dispute fees, investigation fees and cash-withdrawal charges, line by line, with an effective date stamped at the bottom. For UK consumer cards in September 2026 that pack quotes 1.69% for card-present with a 1p minimum per transaction, and 2.19% + 24p online. The second is its licence. Viva is not an intermediary reselling somebody else's acquiring: the group holds a Greek banking licence, acquired with Praxia Bank in 2020, alongside an e-money licence from the Bank of Greece, and it describes itself as Europe's first full tech bank for businesses, operating across 29 European countries. J.P. Morgan has owned 48.5% since December 2022, with the founders holding the balance — a stake that has also produced several years of shareholder litigation between the two.

takepayments

ISO

B

takepayments is a Stockport-based reseller of card machines, online payments and POS systems to UK small businesses, and since June 2024 it has been a Global Payments company. It does not hold your merchant agreement: its own terms make clear that a customer enters a separate contract with an acquiring bank for the transaction processing, while takepayments supplies the terminal, the onboarding, the PCI compliance help and the support line. Two things stand out. The first is its service record, which is the strongest of any provider reviewed on this site by volume: 4.8 on Trustpilot across 66,994 reviews, 94% of them five-star, with more than 6,000 arriving in the last twelve months. The second is that it publishes no prices whatsoever. Rates, standing charges and terminal costs are all quoted by a field consultant after a visit, on a twelve-month minimum term that then runs monthly. The company is older than its name suggests: Companies House records the entity as incorporated on 14 September 1995 and shows it trading as Targeted Transaction Managed Services, then Alphyra UK, then Payzone UK, before taking the takepayments name in December 2019.

Paystand

Bank / A2A Payments

B-

Paystand is a California B2B payments and accounts-receivable company, founded in 2013 by Jeremy Almond and Scott Campbell, built on a premise that inverts how this industry normally charges: you pay a flat monthly subscription rather than a percentage of every transaction. Its own bank-to-bank network carries payments between businesses at no transaction fee, while card and ACH acceptance are resold at what it describes as pre-negotiated wholesale rates, and the software sits on top automating invoicing, collections and reconciliation against ERP systems like NetSuite. It bought the spend-management company Teampay in April 2024, which took it into accounts payable as well, and it says the combined network now touches more than a million businesses with over $20bn in payment volume processed. In April 2026 it launched USDb, a stablecoin backed one-to-one by dollar reserves and issued on two Bitcoin layers — a genuine strategic bet, and the thing most likely to decide whether a given finance team sees Paystand as forward-looking or as a risk it does not need.

Swipesum

Agent Office / Reseller

B

Swipesum is a St. Louis payments advisory founded in 2016 by brothers Michael and Stephen Seaman, and it sells something most companies in this market do not: advice about the processor you already have. Its core work is the statement audit — running a merchant's monthly processing statement through its own software, called Staitment, to separate interchange from processor markup, identify what is negotiable, and quantify what is being overpaid. From there it will renegotiate with the incumbent, run a competitive process across a network it describes as more than seventy providers, and handle the implementation. It describes itself as a fractional chief payments officer rather than an independent sales organisation, and unusually for this corner of the industry it publishes actual prices: the evaluation and implementation service is free, enterprise consulting starts at $50 an hour, and a single statement analysis is $75. It claims to have analysed over $300.5 billion in processing volume since 2016, and it has made the Inc. 5000 three years running — No. 729 in 2023, No. 666 in 2024, and again in 2025.

Sunbit

BNPL Network

B

Sunbit is a Los Angeles financing company, founded in 2016, that puts pay-over-time options at the counter of everyday service businesses rather than at an online checkout. Its natural habitat is the unplanned bill: a $1,400 transmission repair, a root canal, a dog that swallowed something it should not have. The technology and the servicing are Sunbit's; the credit itself is not. Loans and the Sunbit Card are issued by Transportation Alliance Bank, trading as TAB Bank, which is the lender of record. Merchants are told customers can finance totals from $60 to $20,000, that roughly 90% of applicants are approved, and that the application takes about thirty seconds at the point of service. Sunbit's own pages variously describe a network of over 30,000 and over 40,000 locations, concentrated in dentistry, auto service, veterinary care, optical, powersports and general healthcare. The consumer record is unusually good for this category — 4.7 out of 5 across 3,977 Trustpilot reviews and an A+ BBB rating, accredited since 2020 — and Sunbit says it has now made the Forbes Fintech 50 three years running and the Inc. 5000 five. What it does not do is publish what it charges the merchant.

Splitit

BNPL Network

B-

Splitit is an Atlanta-headquartered installment provider that works differently from every other name in buy-now-pay-later. There is no loan, no application and no new account: the shopper pays with a credit card they already hold, Splitit places an authorization on the card for the full purchase amount, and the balance is charged down in monthly or bi-weekly instalments against that same card's existing credit line. Because no credit is being extended, nobody is declined for credit — Splitit advertises approval above 85% against 30–40% for conventional BNPL, and an average order value above $1,000 against roughly $250. The company began life as PayItSimple, rebranded in 2015, listed on the Australian Securities Exchange, then took a $50m investment commitment from Motive Partners, delisted from the ASX and went private in December 2023. It is led by chief executive Nandan Sheth and registered in the United States as Splitit USA Inc., NMLS #2314339. Merchant pricing is quoted rather than published, across four plan tiers whose consumer APR ranges from 0% to 35.99% depending on which side absorbs the cost.

Payabli

Payfac / Aggregator

B

Payabli is a Miami embedded-payments company — legally Centavo, Inc., trading as Payabli — founded in 2020 by William Corbera and Joseph Elias Phillips, who run it as co-chief executives. It does not sell merchant accounts to businesses. It sells payments infrastructure to software companies, so that a property-management system, an HOA portal, a school-district platform or a field-service tool can take payments inside its own product and earn on them, without going through the cost and compliance burden of becoming a payment facilitator itself. The stack is organised as Pay In for acceptance and merchant onboarding, Pay Out for payables, and Pay Ops for the operational layer around both, with a low-code builder called Creator and an AI feature set branded Amigo layered on top. The company is a registered payment facilitator of PNC Bank and Huntington Bank and a registered ISO/MSP of Merrick Bank — an unusually clear disclosure for this part of the market. It raised a $28m Series B in June 2025 led by Fika Ventures and QED Investors, bringing total funding to about $60m, and reported 7x year-on-year revenue growth, more than 50,000 merchants on the platform and billions of dollars in live processing volume.

Fullsteam

Payfac / Aggregator

B-

Fullsteam is a payments and vertical-software holding company founded in 2018 and headquartered in Auburn, Alabama, with a second base in Atlanta. Its model is unusual enough to explain before anything else: rather than selling merchant accounts directly, Fullsteam buys the industry-specific software small businesses already run on — association management, self-storage, field services, healthcare practice management, automotive, wine, hospitality — and embeds its own payment processing into those products. It registered as a Visa payment facilitator in 2019, and by its own account it now employs more than 2,100 people and serves over 60,000 customers, having acquired dozens of software businesses since 2018. For a merchant, that means Fullsteam is usually not a company you chose. It is the company that started processing your payments after the software vendor you did choose was acquired. The product side of that bargain is real: modern embedded payments, one support and reporting layer, and back-office scale a small software vendor could not fund. The commercial side is where the criticism sits. Fullsteam publishes no pricing at all, and a payments-audit firm has documented five rate increases since May 2023, most recently in April 2026.

Aeropay

Bank / A2A Payments

B-

Aeropay is a Chicago pay-by-bank company founded in 2017 by Daniel Muller, and it sells something genuinely different from the merchant accounts most of this site covers: it moves money directly between bank accounts over ACH and the instant rails rather than over the card networks. The business is built around four pieces — Aerosync for connecting a customer's bank account, Pay for taking the debit, Payout for pushing money back out, and Guard for risk — and it is sold to industries where cards are either expensive, awkward or refused outright. That history is the important context. Aeropay found its first real traction in cannabis dispensaries, where card acceptance is a persistent problem, and then moved hard into online gaming; by August 2024 gaming was around 80% of revenue. It raised a $20m Series B in May 2024, led by Group 11, and has assembled a credible list of banking and network partners since — Cross River, MVB Bank, Regent Bank, a Worldpay collaboration for gaming, a Skipify checkout partnership and a Jack Henry integration announced in June 2026. The company publishes no pricing at all, and its consumer-facing record is the problem: the Better Business Bureau rates it F, with a pattern-of-complaints alert and complaints about delayed transfers and unresponsive support.

Zip

BNPL Network

B

Zip is the US buy-now-pay-later network formerly known as Quadpay, owned by the ASX-listed Zip Co Limited. Zip Co was founded in Sydney in 2013 by Larry Diamond and Peter Gray and listed on the Australian Securities Exchange in 2015; the American business it now trades under is Quadpay, a New York company incorporated in August 2017 and bought by Zip in a deal announced in June 2020, approved by shareholders on 31 August 2020 and completed that September. For a merchant the offer is the familiar BNPL trade: let shoppers split a purchase into four instalments over six weeks, get paid up front, and hand the credit and non-payment risk to Zip. What separates Zip from the rest of the category is that it prints a price, and a settlement window to go with it. Its Standard plan is published on its own site at 5.9% plus 30 cents per transaction with no monthly or annual fee, where Afterpay, Klarna and most of the field quote nothing at all and negotiate every deal in private. It also publishes what most of the category will not: that it settles the merchant in full, minus its fees, within two to three business days, and where chargeback liability sits. That 5.9% is nonetheless the highest published headline rate in mainstream BNPL, and Zip's own FAQ confirms it is a floor rather than a ceiling. The parent is now solidly profitable — FY26, the year to 30 June 2026, brought A$16.7 billion of transaction volume, A$1.336 billion of revenue and A$116.4 million of statutory profit, with the US arm growing revenue more than 42% in local currency — but it has also exited Singapore, the United Kingdom and, in August 2026, New Zealand, and in May 2026 lost a unanimous High Court trade mark case in its home market — a loss it settled eight days later by acquiring the disputed mark from Firstmac, avoiding the rebrand the judgment otherwise required and taking on no further damages liability.

Sola

ISO

B

Sola is the brand Fidelity Payment Services and its Cardknox payment gateway have traded under since October 2024. The underlying business is old by payments standards — the Better Business Bureau records it as started on 1 December 1996, and Sola's own history says it began as a retail ISO agent for Heartland Payments before becoming a registered ISO with First Data in 2008, expanding into Canada in 2010, building the Cardknox gateway in 2013, being acquired by the private equity firm H.I.G. in 2017 and passing to PSG in a 2022 acquisition in which H.I.G. stayed on as a minority investor. It is headquartered at the Brooklyn Navy Yard, and the rebrand announcement described it as serving tens of thousands of merchants across a range of industries. What distinguishes it from the crowd of merchant-services resellers is that it owns its gateway rather than renting one: Cardknox is Sola's own product, which is why the company can go after software platforms wanting to embed payments as convincingly as it goes after individual merchants. What it has in common with the crowd is that it publishes no rates, no fees and no contract terms anywhere on its site. Its own footer discloses what it is — a registered Independent Sales Organization of Citizens Bank, N.A. and Elavon, Inc. — which is the most useful sentence on the website.

PAR Technology

POS & Business Software

B

PAR Technology Corporation is a New York Stock Exchange company founded in 1968 in New Hartford, New York, originally as a defense contractor, and now a restaurant-technology business that sold its Government segment to Booz Allen Hamilton in 2024 to concentrate on it. Its cloud point of sale began life outside the company as Brink Software, a San Diego business PAR partnered with from 2011 and acquired in September 2014; rebadged PAR POS, it runs in what the company says is more than 140,000 restaurant locations, including large franchise estates such as Burger King and Papa Johns, and around it PAR sells loyalty and engagement, digital ordering, back-office software, hardware and its own payments product, PAR Pay. The payments proposition is unusual for a point-of-sale vendor and is the most interesting thing here: PAR Pay is deliberately gateway-agnostic — its own marketing says to pick your processor, your hands are never tied — with next-day funding as standard, EMV, NFC and EBT support, tip handling, chargeback tooling, P2PE and PCI compliance and machine-learning fraud scoring across more than 110 transaction signals. The business behind it is growing: second-quarter 2026 revenue of $133.4 million, up 19% year on year, with annual recurring revenue of about $338.0 million, up more than 17%. What PAR does not do is publish a price for any of it.

Basys Processing

ISO

B

Basys Processing is a privately held merchant-services company in Lenexa, Kansas, incorporated in March 2002 and run by its founder, Brad Oddo. Its own footer describes what it is more precisely than its marketing does: a registered Independent Sales Organization of Citizens Bank, N.A., KeyBank, N.A., PNC Bank, N.A. and Merrick Bank. In practice that means Basys sells, prices and supports merchant accounts that settle on partner rails, deploying Fiserv-family and PAX hardware alongside its own IQ Pro gateway, and it reaches most of its merchants through banks, credit unions, software platforms and professional associations rather than through cold outbound. The pitch is service rather than price: US-based in-house support that answers 99% of calls within three rings and resolves 90% of issues on the first, next-day funding, surcharging and cash-discount programs, ACH, recurring billing, QuickBooks and ERP integrations, and a healthcare practice that reaches as far as Epic. The complaint record is remarkably quiet for a company of 24 years — an A+ Better Business Bureau rating, accredited since March 2014, with essentially no complaint volume on file. The gap is the one its own pricing page opens: it is headed 'Total Pricing Transparency' and contains no prices.

Talus Pay

ISO

B-

Talus Pay is a Dallas merchant-services organisation trading as FPT Operating Company, LLC. The business dates to 2006, when it was founded in Dallas as Future Payment Technologies; it took the Talus Pay name in February 2019 following a trademark dispute, and has since consolidated its acquisitions under the master brand Talus. Its Better Business Bureau file records a business start date of 2 December 2016 and accreditation since 10 April 2017 — dates that reflect the current LLC's registration rather than the origin of the business. It has been a portfolio company of the private-equity firm A&M Capital Partners since 2017 and has grown largely by acquisition: Prolific Business Solutions in 2018, three add-on deals during 2019, and Jobox.ai together with Clarus Merchant Services in January 2024. The corporate structure is unusually layered even by ISO standards — AMCP Payments Intermediate Company LLC does business as Talus Pay, Talus Payments, LTD Merchant Services, MSP Consulting, Granite Payment Alliance, Philadelphia Processing, City National Bank Merchant Services and Merchant Bank Partners, and the group is a registered ISO or MSP of Pinnacle Bank dba Synovus Bank, Citizens Bank N.A., Elavon and Esquire Bank. Talus sells a proprietary gateway called Talus Connect, the ReadyPoint point-of-sale line, mobile acceptance, and — through a partnership with Ingenico announced in December 2025 — a hardware-free SoftPOS tap-to-pay product for North America. It holds an A+ BBB rating. It publishes no rates, no fees and no contract terms anywhere.

Revolut Business

Payfac / Aggregator

B

Revolut Business is the merchant-acceptance arm of Revolut, the London fintech founded in 2015 by Nik Storonsky and Vlad Yatsenko. It is unusual in this directory for a simple reason: it publishes a complete rate card. A merchant can read, before speaking to anyone, that in-person domestic consumer Visa and Mastercard transactions cost 0.8% + £0.02, that the same cards online cost 1% + £0.20, that commercial and international cards cost 2.6% + £0.02 in person and 2.8% + £0.20 online, that a Revolut Terminal is £169 + VAT and a Lite Terminal £129 + VAT, and that a chargeback dispute resolved in the merchant's favour returns £15. Acceptance is a sub-account of a Revolut Business account rather than a separate merchant account with a separate provider, so settlement lands in the same balance the business already banks from, in as little as 24 hours. The important limit is geographic: Revolut has offered acquiring across the UK and continental Europe since 2020–21 — its own January 2021 announcement put the count at 29 European countries, a figure it has not refreshed since — and launched a full merchant-acquiring suite in Australia during 2026. It publishes no United States card-acceptance rates. In March 2026 Revolut exited the Bank of England's mobilisation phase and received a full UK banking licence, roughly twenty months after being granted one with restrictions in July 2024.

Nexi

Platform / Acquirer

B

Nexi S.p.A. is one of Europe's largest payments companies, headquartered in Milan and traded on Euronext Milan, and describes itself as Europe's PayTech. It was assembled through consolidation — most consequentially the merger with the Danish group Nets, completed on 1 July 2021, and the merger with the Italian rival SIA, effective 1 January 2022, which together were widely reported as creating the largest European paytech by EBITDA — and now runs three businesses: Merchant Solutions (acquiring and acceptance), Issuing Solutions (card issuing and processing for banks) and Digital Banking Solutions (clearing, open banking, ATM and network services). Adyen carries a far larger market value and Worldline has at times been described as Europe's largest acquirer by revenue, so "largest" depends on the measure — but the scale is not in doubt. In the first half of 2026 the group reported net revenues of €1,736 million, EBITDA of €870 million and merchant transactions of 10,225 million worth €423 billion, with Merchant Solutions accounting for roughly 56% of revenue. What a merchant will not find is a price. Nexi sells overwhelmingly through partner banks and through country brands rather than direct, so acceptance terms are set by whichever bank or channel signs the merchant, and there is no group rate card to compare. The company is also in transition at the top: in March 2026 it appointed Bernardo Mingrone, previously group chief financial officer and CEO of Nexi Payments, to succeed Paolo Bertoluzzo after a decade as chief executive, and the shares fell on the announcement.

Lavu

POS & Business Software

B-

Lavu is an Albuquerque restaurant technology company founded in 2010 by Andy Lim, and it has a genuine claim to being the first restaurant point-of-sale system built for the iPad. It raised a $15 million investment from Aldrich Capital Partners in 2015 — reported at the time as the largest Series A in New Mexico's history — and has since assembled a full restaurant stack around the till: a kitchen display system, online and contactless ordering, a dual-pricing (cash discount) programme, payroll, back office and its own payment processing under the name Lavu Pay. Through 2026 the company repositioned hard around Marty AI, an overnight analysis layer that reads point-of-sale, labour and inventory data and delivers a "Morning Deposit" briefing of recoverable cash to managers before service, published a comparative report on AI capabilities across seven major restaurant POS platforms in March 2026, and now markets itself as an intelligent financial operating system rather than a till. Independent reviewers place its plans at roughly $59, $129 and $279 a month with a three-year commitment; Lavu itself no longer publishes a pricing page.

Afterpay

BNPL Network

B

Afterpay is the buy-now-pay-later network founded in Sydney in October 2014 by Nick Molnar and Anthony Eisen, and owned since January 2022 by Block, Inc. — the deal was announced in August 2021 at a headline US$29 billion and completed on far less, reported at roughly US$14 billion in Class A shares, because Block's own share price had fallen in the interim. For a merchant, the proposition is straightforward: offer shoppers four interest-free instalments over six weeks, or a monthly plan over six or twelve months, get paid up front rather than waiting for the customer to finish paying, and let Afterpay carry the fraud and non-payment risk. In exchange the merchant pays a commission Afterpay does not publish — third-party reviewers consistently report a range around 4% to 6% plus roughly $0.30 per transaction, several times the cost of taking the same sale on a card. Afterpay's own merchant marketing claims a 58% increase in average order value among accepting merchants and $8.6 billion of incremental US sales delivered over the preceding twelve months. Under Block, the product has increasingly become a Cash App feature rather than a standalone checkout button: Afterpay Post-Purchase and, from 2026, Afterpay Pre-Purchase let Cash App Card holders convert everyday card spend into instalments at any merchant, whether or not that merchant has ever signed an Afterpay agreement.

Wave (Wave Financial)

Payfac / Aggregator

B-

Wave is a Toronto software company, started in April 2010, that gives away accounting and invoicing to very small businesses and makes its money when those invoices get paid. H&R Block bought it for $405 million in a deal that closed on 1 July 2019, and it has been a subsidiary ever since. Payments run at 2.9% plus 60 cents for Visa, Mastercard and Discover, 3.4% plus 60 cents for American Express, and 1% with a $1 minimum for bank payments, with no monthly fee on the free Starter plan; a $19-a-month Pro plan waives the 60-cent card fee on the first ten transactions each month and adds features. Card money lands in one to two business days, bank payments in one to seven, and eligible accounts can pull an instant payout to a debit card for a further 1%. Since November 2020 Wave has served the United States and Canada only. Its US card processing is powered by Adyen and Stripe, which Wave discloses in its own terms.

PaySimple

Payfac / Aggregator

B-

PaySimple is a Denver payments-and-billing platform for service businesses — the kind that invoice, take deposits and bill the same customers month after month rather than ring up a counter. Its own about page dates the business to 2006 and puts it at more than 22,000 businesses; the site footer carries a 2005 copyright and the Better Business Bureau file records a December 2006 start, so the exact birth year depends on which document you read. What matters more is the lineage: the company Eric Remer founded as PaySimple is the company that was incorporated as EverCommerce in 2016 and listed on Nasdaq in 2021. PaySimple was not bought by EverCommerce so much as it became it, and the brand now sits inside that group as one product among many — the BBB file is registered to "EverCommerce Solutions Inc., DBA PaySimple Inc." PaySimple is a registered ISO of Fifth Third Bank and of Wells Fargo Bank. Pricing is published in full and unusually plain: $79.95 a month with every feature included, 2.9% plus 30 cents on cards, 1% plus 30 cents on ACH, no contract and no cancellation fee.

Bluefin

Gateway / Orchestration

B

Bluefin is an Atlanta company that sells payment security rather than payment processing. Founded in 2007 and originally trading as Capital Payments, LLC doing business as Bluefin Payment Systems, it built its business on PCI-validated point-to-point encryption — technology that scrambles card data inside the terminal at the moment of the tap, so that what travels through the merchant's systems is already worthless to a thief. Around that it has assembled a gateway (PayConex), a decryption service sold to other processors and gateways (Decryptx), a tokenization platform for personal, health and card data (ShieldConex) and, more recently, a proxy layer called PointConex that adds validated encryption without forcing anyone to recertify their processor integrations. Bluefin says it now supports more than 40,000 customers across 60 countries through over 300 integration partners. Its headquarters is in Atlanta, with offices in Waterford, Ireland and Vienna, Austria; the Vienna presence came with its November 2022 acquisition of TECS Payment Systems. The Better Business Bureau rates it A+ and has accredited it since July 2017.

Sezzle

BNPL Network

B-

Sezzle is a Minneapolis buy-now-pay-later provider founded in 2016; Charlie Youakim, Paul Paradis and Killian Brackey are the co-founders named most consistently, though accounts of the full founding team differ. It began as a next-business-day ACH product and pivoted to instalments in 2017, listed on the Australian Securities Exchange on 30 July 2019, began trading on Nasdaq as SEZL on 17 August 2023 and left the ASX in January 2024. For the quarter ended 30 June 2026 it reported gross merchandise volume of $1.3 billion, up 37.9% year on year, total revenue of $149.7 million, up 51.7%, and net income of $40.8 million. For a merchant the bargain is the standard BNPL one but unusually cleanly stated: the shopper pays Sezzle a down payment, Sezzle pays you the full order value less your merchant rate, and Sezzle then carries both the fraud risk and the repayment risk for the six weeks that follow. What Sezzle does not do is tell you what that costs. There is no published merchant rate anywhere on its site — the fee is in the agreement you sign — and there are three separate ancillary charges most merchants only meet after signing.

QuickBooks Payments (Intuit)

Payfac / Aggregator

B

QuickBooks Payments is Intuit's card and bank-payment service, sold as an add-on to QuickBooks Online rather than as a standalone merchant account. Intuit was founded in 1983 and is headquartered in Mountain View, California; money movement is provided by Intuit Payments Inc., licensed as a money transmitter by the New York State Department of Financial Services, and the card acquiring itself runs through JPMorgan Chase Bank, N.A. and Paymentech, LLC under the commercial entity merchant agreement Intuit publishes. Rates are published in full and, as of the figures Intuit dated 30 April 2026, are 2.5% for in-person payments, 2.99% for invoices and other card and digital-wallet transactions, 1% for ACH bank payments, 3.5% for keyed cards, and 2.99% for buy-now-pay-later through Affirm. There is no monthly fee for Payments itself, no minimum and no long-term contract. The defining trade-off is reconciliation: nothing else puts card, ACH, PayPal, Venmo and Affirm volume straight into your books with no matching step, and nothing else in this price band has quite the same reputation for freezing deposits.

Melio

Bank / A2A Payments

B-

Melio is a US business bill-pay and accounts-payable platform founded in 2018 by Matan Bar, Ilan Atias and Ziv Paz, headquartered in New York with an R&D centre in Tel Aviv. It is not a card acquirer: instead of helping you take money from customers, it moves money out to your suppliers, letting you pay any vendor by ACH, cheque, wire or card even when that vendor accepts none of those, and syncing the result into QuickBooks, Xero or NetSuite. Xero announced its acquisition of Melio in June 2025 and completed it on 15 October 2025 for US$2.5 billion upfront in cash and equity, with up to a further US$0.5 billion payable over three years. Xero's announcement put Melio at 80,000 customers, more than US$30 billion of payments processed in FY25 and US$153 million of FY25 revenue. Melio publishes its entire fee schedule, which is rare in this market and the single strongest thing about it. Against that sits a Better Business Bureau rating of F and a large, consistent body of complaints about accounts suspended mid-payment with funds already in transit.

CardFlight (SwipeSimple)

Gateway / Orchestration

B-

CardFlight is a New York software company, founded in 2013 by Derek Webster, whose product SwipeSimple is the payment-acceptance app a great many American small businesses use without ever hearing the name CardFlight. That is by design: CardFlight has historically sold through banks, merchant acquirers and independent sales organisations, which rebrand or resell SwipeSimple to their own merchants, and the company says ten of the top thirty US merchant acquirers and ISOs have selected it as their preferred small-business acceptance product. It reports more than 125,000 small businesses on the platform as of August 2026. Alongside that channel business it now sells direct, as SwipeSimple Connect, with fully published pricing: 2.6% plus 10 cents in person, 3.5% plus 10 cents keyed, no monthly, annual, batch, statement or PCI fees, no contract, a $49 mobile reader and a $299 smart terminal. WestView Capital Partners took a growth stake in October 2024.

Payline Data

ISO

B

Payline Data is a Chicago merchant account provider that publishes its whole interchange-plus rate card on its home page: interchange plus 0.35% and 10 cents under $50,000 of monthly volume, sliding to interchange plus 0.15% and 8 cents above $1 million. That alone puts it in a small minority of US processors. It advertises no application fee, no cancellation fee and no term length, does not charge for PCI compliance, and funds next day. It is a registered ISO of Wells Fargo Bank N.A. and Fifth Third Bank N.A., says it serves more than 20,000 merchants, and takes high-risk business including nutraceuticals, subscriptions, firearms, CBD and adult. The complication a reader should know before signing is ownership: Payline was bought by Pineapple Payments in October 2017, and Fiserv bought Pineapple in May 2021, so Payline has been a Fiserv brand for five years. Nothing on Payline's own site says so.

Nayax

Payfac / Aggregator

B-

Nayax is an Israeli payments and commerce platform built for unattended retail — vending machines, kiosks, car washes, laundromats, amusement machines, coffee service and, increasingly, EV charging. Founded in 2005 by Yair Nechmad and David Ben Avi and headquartered in Herzliya, it listed on the Tel Aviv Stock Exchange in May 2021 and on Nasdaq in September 2022. In the second quarter of 2026 it reported revenue of $122.6 million, up 28.2%, on total transaction value of $2.056 billion across 815 million transactions, 1.553 million managed and connected devices and 125,400 customers, at a blended take rate of 2.62%. Its US retail plan is published at $99 a month with no transaction fee on the first $5,000 of monthly volume. Against that: a February 2025 consent decree with the Israeli Competition Authority over its OTI acquisition, a July 2026 cloud security incident, 79 BBB complaints in three years and a 2.2-star Trustpilot.

Electronic Payments

ISO

B

Electronic Payments, Inc. — usually EPI — is a Calverton, New York merchant acquirer founded on 20 May 2000 by Michael Nardy while he was a student at Boston College. It is one of the few mid-sized US acquirers that runs its own stack rather than reselling somebody else's: Cygma, launched in 2023, is EPI's own authorization and clearing platform, and Exatouch, ProCharge, eGiftSolutions and the Vault gateway are in-house products. The company says it processes more than $26.5 billion a year across 60,000+ merchant partnerships and 486 million transactions, and calls itself the 23rd largest US acquirer. It bought UK-based Handpoint in August 2025, adding roughly 100 ISV integrations, 18,000 connected devices and more than $2 billion of annual volume plus reach into Canada, the UK and over 20 EEA markets. Its BBB file is unusually clean — A+, accredited since 2010, four complaints in three years. It publishes no pricing whatsoever.

dLocal

Platform / Acquirer

B-

dLocal is an emerging-markets payment platform founded in 2016 in Montevideo, Uruguay by Sergio Fogel and Andres Bzurovski, and listed on Nasdaq since June 2021 as DLO. It exists to solve one problem: a global business that wants to sell in Brazil, India, Nigeria or Indonesia has to accept Pix, boleto, GCash, M-Pesa, UPI and local cards, and settle in currencies with capital controls. dLocal covers 60+ countries and more than 1,000 payment methods through a single integration, and counts Amazon, Shopify, Dropbox, Mailchimp, Shein and Tripadvisor among its merchants. In 2025 it processed $41 billion of total payment volume, up 60%, on revenue of $1.09 billion and gross profit of $403 million. It is also the most legally scrutinised company in this category: two Muddy Waters short reports in late 2022, a reported Argentine government investigation in 2023, a New York IPO-disclosure class action that was dismissed and whose dismissal was upheld on appeal in April 2026, and a separate federal securities case in the Eastern District of New York that is still live.

Affirm

BNPL Network

B-

Affirm is a buy-now-pay-later provider founded in 2012 by Max Levchin, Nathan Gettings, Jeffrey Kaditz and Alex Rampell, headquartered at 221 Main Street in San Francisco and listed on Nasdaq as AFRM since January 2021. For the fiscal year ended 30 June 2026 it reported $50.2 billion of gross merchandise volume, up 37%, across approximately 571,000 active merchants and 27.8 million active consumers. Merchants integrate Affirm as a checkout option, Affirm underwrites and funds the consumer, and the merchant is paid in full up front minus a fee. Two things make it materially different from card acceptance: Affirm bears the consumer fraud risk on transactions it approves, and the merchant fee is several times a card rate — third-party surveys of mid-market merchants report 2% to 8%, while Affirm's own filings put blended merchant network revenue at 2.3% of GMV in FY2026. Its BBB profile is A+ and accredited; its consumer Trustpilot score is 1.7 across roughly 7,700 reviews.

Xsolla

Merchant of Record

B-

Xsolla is a merchant of record built specifically for video games, founded in Perm, Russia in 2005 as 2Pay by Aleksandr Agapitov, renamed Xsolla in 2011 and headquartered in Sherman Oaks, Los Angeles since the company moved to California in 2010. It becomes the legal seller of your game or in-game item, which transfers sales tax, VAT, fraud loss and chargeback liability off the developer and onto Xsolla, and it is the dominant option for direct-to-player web shops that route around the 30% mobile app store cut. Its marketing describes a revenue share as low as 5%, with over 1,000 payment methods across 200-plus markets, 130-plus currencies and 25-plus languages. It publishes no full rate card, and its recent corporate history — a 2021 mass dismissal driven by workforce analytics, six former-executive lawsuits since 2019, and a 2024 Bloomberg investigation into more than $100 million moving between company and founder accounts — deserves as much of a developer's attention as the pricing does.

Moov Financial is a US payments platform for software companies, built by Wade Arnold and Bob Smith out of the open-source moov.io money-movement libraries Arnold began publishing in 2017. It sells one API that accepts cards and bank payments, holds balances in wallets, sends payouts by RTP, FedNow or push-to-card, and issues virtual cards — the full money-movement stack that a vertical SaaS company would otherwise assemble from four vendors. It is the rare payments company that publishes a complete rate card: interchange plus 0.60% and 15 cents for online card acceptance, interchange plus 0.50% and 15 cents for Tap to Pay, 25 cents for next-day ACH, and a $500 monthly minimum with no setup fee. It has raised roughly $77.5 million across three named rounds, with Visa, Andreessen Horowitz, Bain Capital Ventures and Commerce Ventures on the register, and it operates in the United States only.

Ingenico is the French payment terminal manufacturer behind a large share of the card readers on the world's counters, founded in Suresnes in 1980 and today selling terminals, SoftPOS and its Ingenico 360 cloud platform through banks, acquirers and ISVs rather than direct to merchants. Its own site claims roughly 3,000 staff across 52 offices in 32 countries, deployments in more than 120 countries, tens of millions of terminals in the field, over 1,000 bank and acquirer clients and 2,500-plus payment applications. It publishes no merchant pricing, because merchants are not its customers. The story of 2026 is financial rather than technical: after Apollo bought it from Worldline in 2022, Ingenico opened talks with its lenders in April 2026 over an interest bill it could not carry, and in August 2026 announced a recapitalisation that converted part of its debt to equity, brought in EUR 150 million of new money from a PIMCO-led group and removed Apollo from the shareholder register entirely.

First Card Payments

First Card Payments is a high-risk merchant account provider operating from Brickell Avenue in Miami with a second office in Los Angeles, trading under the legal name Ellis Financial Holdings Corp with Alexander Ellis as president. It is a broker rather than a processor: it places accounts with what it describes as more than 30 banking and ISO partners, across 40-plus verticals that ordinary processors decline — adult, CBD, firearms, nutraceuticals, debt relief, travel, forex, gaming, dropshipping and pharmacy among them. It holds an A+ rating with the Better Business Bureau without being accredited, and the BBB records the business as starting on 2 December 2015. It publishes no rates, no fees, no reserve terms and no contract terms anywhere on its site, and it appears in Fit Small Business's 2026 shortlist of high-risk providers as the pick for a one-stop account setup.

BitPay

Payfac / Aggregator

B-

BitPay is a cryptocurrency payment processor founded in May 2011 by Tony Gallippi and Stephen Pair, now based in Alpharetta, Georgia, and by its own description the world's longest-operating crypto payments company. A merchant is quoted in fiat, the customer pays in bitcoin, a stablecoin or another supported asset, and BitPay settles to the merchant's bank account in dollars on the next business day, absorbing the price movement. Its merchant pricing is published in full — 2% + 25 cents under $500,000 a month, 1.5% + 25 cents to $999,999, and 1% + 25 cents above $1 million — which puts it ahead of most of the payments industry on transparency. Crypto payments are push transactions, so there are no chargebacks. The company holds a BBB A without accreditation, settled with the US Treasury's sanctions office in 2021 over 2,102 apparent violations, and carries a 1.2-star Trustpilot score driven overwhelmingly by consumers using its wallet rather than by merchants.

Trustly

Bank / A2A Payments

Trustly is a Swedish open-banking payments company, launched in Stockholm in 2008, that moves money directly from a shopper's bank account to a merchant's — bypassing the card networks entirely. It is, on its own account, the largest pay-by-bank provider in the world by volume — a ranking no independent source confirms: its full year 2025 results report processed volume up 17.6% to SEK 1,059.0 billion, the first year it has carried more than $100 billion in total payment value, and it passed 120 million users in April 2026. Revenue, however, fell 12% on a constant-currency basis to SEK 2,427.7 million and it made a SEK 565.0 million loss after tax, a year into a 24-month transformation programme. It is regulated in Sweden and the UK, and in February 2022 the Swedish Financial Supervisory Authority issued it a warning and a SEK 130 million fine for serious anti-money-laundering failings. It publishes no merchant pricing.

Spreedly is a payment orchestration platform and PCI-compliant card vault founded in 2007 and run from Durham, North Carolina. It does not process payments itself. It stores your customers' card credentials in its own vault, connects them to more than 140 payment gateways through one API, and routes, retries and optimises transactions across them. It reported annual gross merchandise volume expected to exceed $60 billion for 2025, up from $50 billion in 2024, across more than 400 customers in 100-plus countries. Entry pricing for the vault starts at $750 a month; everything above that is quoted. It is enterprise infrastructure, not a merchant account, and a small business should not be shopping for it.

For a retailer it is not a merchant account — it is an additional payment method that sits alongside card acceptance, sold on the promise of higher conversion and larger baskets, and priced far above card interchange. Klarna publishes no US rate card, its dispute process runs on its own rules rather than the card networks', and it is defending a securities class action filed after its IPO.

A vertical payments company you probably meet through your software, not through a salesperson. REPAY — legally M & A Ventures, LLC doing business as REPAY, and known in full as Realtime Electronic Payments — was founded in 2006 and is headquartered in Atlanta. It is publicly traded as RPAY and reported full-year 2025 revenue of $309.3 million, split between a Consumer Payments segment at $285.9 million and a Business Payments segment at $48.4 million, with 2026 guidance of $340 to $346 million. Its business is embedding payment acceptance and vendor disbursement inside the software that particular industries already run: consumer lenders, auto dealers and their finance arms, credit unions, receivables management firms, municipalities, healthcare, HOA and property management. The distinctive products are the ones a general processor does not build — Instant Funding, which pushes loan proceeds to a borrower's debit card in real time through Visa Direct, and an AP automation network REPAY says exceeded 602,000 suppliers at the end of 2025.

NCR Voyix

POS & Business Software

B-

The retail and restaurant half of the old NCR. NCR Corporation — founded in 1884 as the National Cash Register Company — renamed itself NCR Voyix in October 2023 when it spun off its ATM business as NCR Atleos, and what remains is a unified commerce platform: Aloha and Counterpoint point of sale, self-checkout, and Voyix Pay processing sold alongside them. The scale is real. NCR Voyix reported 80,000 platform sites and more than 8,500 payment sites at the end of 2025, $1.7 billion of annual recurring revenue, and full-year Software and Services revenue of $1,986 million. The problem is the paper you sign. The published US merchant agreement sets a 36-month initial term that auto-renews for 12-month periods unless you give 60 days' notice, makes cancellation during the term immediately payable for every remaining month, and reserves an annual price increase of CPI plus 5% — with a contractual floor of 5% — that applies during the initial term as well as after it. Buy the platform if the platform is what you need, and negotiate the term before you sign anything.

Leap Payments

ISO

B-

A sales organisation with an unusually good promise and an unusually poor paper trail. Leap Payments sells interchange-plus pricing to every customer and attaches a Lifetime Rate Lock: its own processing, authorization and monthly account fees will not rise for the life of the account, with interchange itself passing through at cost in both directions. That is a better structure than most small merchants are offered, and the company has real standing behind it — it was named the number one MSP/ISO in Elavon's Western Region for merchant activations at Elavon's 2019 conference. The trouble is that you cannot verify anything else. No rate, no markup, no monthly fee and no contract term is published. Sources disagree on whether the agreement is month-to-month with no early termination fee or a three-year term with a $295 exit fee. Its own site says it is a sales office for WorldPay, an FIS Global company — a description stale on two counts by 2026 — while independent reviewers describe it as a registered ISO and MSP of Elavon. And the Better Business Bureau, which the company's marketing history leans on, currently shows no rating at all.

CSG Forte

A biller-focused processor that does ACH properly. Forte Payment Systems was founded in Texas in 1998 and acquired by CSG Systems International on 1 October 2018, becoming CSG Forte; CSG itself was taken private by NEC's Netcracker subsidiary on 14 May 2026, so the parent above this business changed hands very recently. The company says it handles 260 million transactions and more than $195 billion a year for roughly 175,000 merchants, and it sells almost entirely into recurring-billing verticals — utilities, government, insurance, healthcare, property management, telecoms. Two things set it apart. It is a registered acquirer as well as a gateway, operating as an Elavon Payments MSP and a Registered MSP/ISO of Elavon, Inc., Georgia, and it publishes unusually honest documentation of how ACH actually settles, including the awkward fact that standard funding can take up to six business days. Against that, no rates are published, the standard agreement runs three years, and the BBB file shows unanswered complaints and merchants struggling to stop billing after cancellation.

Bankful sells gateway plans off a public page — $0 a month with a $50 monthly minimum and $0.15 a transaction at the bottom, $495 a month and $0.08 a transaction at the top — and lists the add-on costs alongside them, down to $38 per Ethoca alert and $1.60 per eCheck authentication. It is an officially supported third-party gateway for WooCommerce and works with BigCommerce, Wix, Ecwid and Shopify, and it accepts categories those platforms' own processors decline: CBD, nutraceuticals, firearms, tobacco, adult, dating, bail bonds and tech support. The reservations are substantial and you should weigh them properly. The card processing rate — the number that actually determines your cost — is not published, only the gateway fee on top of it. The independent record is polarised: an A+ Better Business Bureau file, accredited since 2020, against a 2.1 Trustpilot score where 91% of eleven reviews are one star. And Bankful shares a suite address and a co-founder with eMerchantBroker, so treat the two as one commercial relationship rather than two quotes.

No. 900778), has been a principal member of Visa Europe and Mastercard since 2012, launched its own gateway in 2013 and its own acquiring division in 2014, and runs card-present alongside online and mobile. It underwrites verticals most acquirers decline — gaming, forex, travel, subscriptions — which makes it a genuine option for merchants who have been turned down elsewhere, without being a broker reselling somebody else's appetite for risk. The catch is the usual one: no published pricing, quotes come from sales after underwriting, and high-risk accounts should expect a rolling reserve.

An API for moving money between US bank accounts, founded in Des Moines in 2008 and one of the earliest companies to make ACH programmable.

That is a genuinely useful thing to be able to buy, and Dwolla has been doing it longer than almost anyone. Two things should temper the enthusiasm. It no longer publishes any pricing — the pricing page now says only that terms are tailored to volume, rails and integration — and in May 2026 Dwolla was acquired by NMI, which is folding its capabilities into NMI's embedded payments platform. NMI says it will keep supporting existing Dwolla customers; neither company has said whether the Dwolla brand and product survive the integration.

Amazon's merchant payments business dates to the Amazon Flexible Payments Service beta in August 2007; the product merchants use today launched as Login and Pay with Amazon on 8 October 2013 and took the Amazon Pay name later. A shopper clicks it, signs in with the Amazon account they already have, and pays with a card and address Amazon already holds. Pricing is published and ordinary — 2.9% plus a $0.30 authorization fee on US domestic transactions, 3.9% plus $0.30 when the card was issued abroad, no monthly fee and no setup fee — and Express Payout will fund a US bank account within 24 hours including weekends, for free. What Amazon Pay is not is a merchant account. It is online-only, it has no card-present product, its acceptable use policy bans a long list of categories outright including CBD regardless of state law, and it only ever captures the slice of your checkout that Amazon shoppers choose.

The last two years have been brutal: a June 2025 investigative report accused it of knowingly processing for prohibited and high-risk clients, Belgian prosecutors opened a money-laundering probe into its local unit, the shares fell more than 40%, and S&P cut the credit rating to junk in August 2025.

What it does not have is much of a public record: 42 Trustpilot reviews, every single one of them five stars, no BBB profile we could find, and no named acquiring banks.

The payments business is real but not growing — $22.3 million of processing revenue in the first half of 2026, down from $24.0 million a year earlier — and it publishes no rates at all.

The trade-offs are the ordinary ISO ones — a three-year term and a per-location early termination fee reported at $395, a PCI non-compliance charge around $25 a month, and an annual fee that steps up after year one. Nothing here is published by the company, which is the recurring frustration.

It runs its own gateway, its own POS line and its own boarding and reporting APIs, which makes it a credible one-integration partner for software platforms and ISOs. What it does not do is publish a price. Payroc sells almost entirely through commission-paid agents and referral partners, so the rate, the term and the cancellation fee you get are set by whoever signs you, and the most consistent merchant complaint is being told there was no early termination fee and then being billed several hundred dollars for one.

Its formal complaint record is the cleanest of any provider we have reviewed at this size — one BBB complaint in three years against an A+ rating held since 2005. The two things to weigh against that are a markup that independent auditors have found higher than competing quotes, and a 2025 data breach at a third-party vendor that exposed Social Security numbers and banking details for 22,278 people and is now the subject of a proposed class action.

Three things to know: it publishes no pricing at all, it holds reserves that merchants say run into six figures, and it is now a North brand, so a quote from Humboldt and a quote from North American Bancard are not two independent quotes.

Heartland Payment Systems

Platform / Acquirer

B-

A large US small-business processor founded in 1997, bought by Global Payments for $4.3 billion in 2016 and now openly in the middle of being retired as a brand — Global Payments' own page is headed "Heartland Payment Systems is now Global Payments." It still sells under the Heartland name at heartland.us, still runs the Merchant Bill of Rights it invented, and still publishes no pricing. Signing today means signing with a brand that is being folded away around you.

SpotOn

POS & Business Software

B-

A restaurant-first point-of-sale and payments platform founded in 2017, with published plan rates, next-morning funding and unusually well-regarded support. The catch is the contract: a two-year minimum on its headline plan, a mid-2026 rate increase applied to existing merchants, and cancellation terms it does not publish.

Segpay

Merchant of Record

B

A South Florida high-risk biller founded in 2005, registered with Visa as an internet payment service provider and with Mastercard as a payment facilitator, serving adult, dating, subscription and content merchants across the US, EU, UK and Australia. It publishes its settlement terms in detail and its rates not at all.

PayJunction

ISO

B+

A Santa Barbara ISO that has been processing since 2000, sells month-to-month with no cancellation fee, and has zero complaints on file with the BBB. The reservation is pricing: its published numbers are all 'as low as', and third-party accounts of its monthly fee flatly contradict each other.

Mollie

Payfac / Aggregator

B+

One of Europe's largest independent payment service providers, serving more than 250,000 businesses from Amsterdam and authorised by the Dutch central bank as an electronic money institution. It publishes its full price list, which almost nobody at its scale does, and it is in the middle of absorbing GoCardless in a €1.05 billion deal. It processes for Europe and the UK only, and account freezes are the recurring complaint.

pmtbox (formerly National Processing)

ISO

B-

A 2007-vintage Utah merchant services provider that spent years as one of the better-regarded small-business ISOs, rebranded to pmtbox, raised $15 million in 2026, and repositioned around enterprise e-commerce. The track record is real; the offering a small merchant would be buying today is much less clear than it was.

GoDaddy Payments

Payfac / Aggregator

B

GoDaddy's in-house processor, built on the Poynt technology it bought in 2020. Flat published rates, no monthly fee and next-business-day payouts make it a genuinely competitive small-business option — provided you are willing to run your commerce inside GoDaddy's ecosystem.

GoCardless

Bank / A2A Payments

B

A bank-payments specialist built for recurring billing. GoCardless collects by ACH and other direct debit schemes rather than by card, with published, capped per-transaction pricing — but it processes no card payments at all, and merchant complaints about account freezes and slow support are persistent.

It will underwrite what almost nobody else will — but it publishes no rates, and its contract terms deserve a careful read.

Rainforest

Payfac / Aggregator

B

An Atlanta payfac-as-a-service provider that publishes its entire buy-rate card in public — 0.30% and $0.30 falling to 0.20% and $0.20 at volume, with no revenue share — for software platforms embedding payments. Not a merchant account, and only four years old.

Host Merchant Services

ISO

B+

A Delaware ISO that publishes real interchange-plus margins — 0.25% and $0.10 retail, 0.20% and $0.09 restaurant, 0.35% and $0.10 e-commerce — on month-to-month terms with no termination fee, an A+ BBB record since 2011 and 4.6 on Trustpilot.

Finix

Payfac / Aggregator

B

A San Francisco processor that charges a monthly subscription — from $250 — and takes zero markup on interchange, billing a flat $0.08 or $0.15 per transaction instead. Excellent economics above roughly $1m a year, wrong below it, and with a public track record still too thin to lean on.

Its own marketing overstates its Trustpilot score, and its BBB rating is D- for unanswered complaints.

eMerchantBroker

ISO

B

A long-established California high-risk specialist with an A+ BBB rating, accreditation since 2012 and an unusually light complaint record. The trade-offs are tiered, quote-only pricing at the expensive end of the market and multi-year contracts with early termination fees up to $595.

B

Nuvei is a Montreal-based global payment technology company founded in 2003 that offers 700+ payment methods across 200+ markets and deep vertical expertise in iGaming, fintech, and high-risk sectors — but carries meaningful risks around contract terms, pricing transparency, and customer support quality.

Chase Payment Solutions and Merchant Services

Platform / Acquirer

B

Chase Payment Solutions is the merchant services arm of the #1 US bank, offering small and mid-sized businesses a deeply integrated combination of payment processing, same-day deposits, and banking tools. They're backed by the trust and scale of JPMorgan Chase but with flat-rate fees that may not suit high-volume merchants.

Toast POS

POS & Business Software

B

Toast POS is the leading all-in-one cloud-based restaurant management platform, purpose-built for the food service industry with deep features for ordering, payments, payroll, and analytics, but comes with restrictive multi-year contracts, mandatory payment processor lock-in, and a history of transparency controversies.

WooPayments (Automattic)

WooPayments is the official, Stripe-powered payment solution built exclusively for WooCommerce stores, offering no monthly fees and deep dashboard integration, but plagued by account suspension issues and inconsistent customer support that undermine trust for serious merchants.

Payment Cloud

Agent Office / Reseller

B+

A well-run high-risk merchant services shop with unusually good service ratings and no junk fees — but since its 2024 acquisition it is a Kurv company, and Kurv now routes almost everything through its own platform, which is not the bank-agnostic brokerage the brand's reputation was built on.
