3.5% + $0.15 per e-commerce transaction, on the same non-swipe rate as keyed payments

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

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

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

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.

Gumroad

Merchant of Record

C+

Gumroad is a storefront and checkout for people selling digital products — e-books, courses, software, memberships, design assets — founded in San Francisco in 2011 by Sahil Lavingia and, since 1 January 2025, the merchant of record on every sale, which means it charges, collects and remits sales tax, VAT and GST worldwide and handles disputes with buyers. It says creators have earned more than $1 billion through it, and in April 2025 it published its entire codebase under an MIT licence. Lavingia stepped down as chief executive in November 2025 after 14 years, handing over to long-time engineer Ershad Kunnakkadan. The price of the simplicity is high: 10% plus $0.50 on every direct sale, plus card processing at 2.9% plus $0.30, and a flat 30% on sales that come through Gumroad's Discover marketplace; only sellers passing $20,000 in a calendar month drop to 5% plus $0.50. There is no monthly fee, refunds return Gumroad's share, and chargebacks cost the creator the sale and the processing fee but no penalty. Payouts are weekly on a fixed weekday by country, after a seven-day hold, and — since a change creators noticed in March 2026 — only once the balance reaches $100. Public reviews are poor: the Trustpilot profile scores 1.4 from about 415 reviews, most of them about held or missing payouts and support that is hard to reach.

Barclaycard Payments

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

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

Expert grade BRead review →

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

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.
