The evidence

Every number is published — or marked absent.

Rates, fees, payout times and contract terms come from published documentation and public filings — never from a sales call. Each review carries the date it was last fact-checked.

Where a provider doesn't disclose a number, the review says so. We don't estimate, and we don't fill gaps with marketing copy.

Every value above is published by the provider. A processor that doesn't publish a number gets “Not disclosed” in that cell — never an estimate.

The grade

Six criteria, scored in the open.

Pricing transparency, feature set, ease of use, customer support, contract terms and industry reputation — every review scores all six, and the grade is what the scores say it is.

No pay-to-play, no sponsored placements. A provider can't buy a better grade; they can only earn one, and the reasoning is published either way.

Head to head

Put any two head to head.

Same criteria, same evidence, side by side — with a winner called per row and overall, and the reasoning for each call.

Where the honest answer is “it depends on your business”, the comparison says that instead of forcing a verdict. And it's not just the featured matchups — any two of the reviewed processors can be compared.

A grade you can trust has to be allowed to be bad. Every item in this feed links to the review that documents it.

NOWPayments

Gateway / Orchestration
B-

NOWPayments is a cryptocurrency payment gateway launched in 2019 by the team behind the ChangeNOW crypto exchange. It lets a business take payments in more than 350 crypto assets through an API, invoices, payment links, plugins, donation widgets, subscriptions and a browser-based point of sale. Each payment can be forwarded to the merchant's own wallet or held in an optional custody balance, which a third-party provider runs. As of October 2026 its pricing page lists a 1% service fee on payments received and settled in the same coin and 1.5% when the payment is converted or taken at a fixed rate, plus blockchain network fees. Payouts and mass payouts carry no service fee, only network fees. There is no monthly fee, setup fee or contract. The operator is FD Transfers LLC, registered in St. Vincent and the Grenadines with a postal address in Tallinn, Estonia. Its Terms of Service, updated 19 October 2026, say (in section 15.1) that the services are not provided to residents or citizens of the United States, the United Kingdom, the European Union, the UAE or Russia, and that the company can close an account at any time without giving a reason. The US, UK and EU exclusion was already in the April 2026 terms; the UAE and Russia were added later in 2026. We found no regulator licence for NOWPayments itself. Trustpilot rates it 4.5 from 1,122 reviews, but 13% are one-star, and some of those describe blocked accounts and withheld funds.

Easebuzz

Payfac / Aggregator
B-

Easebuzz is a payment aggregator based in Pune, India. It sells an online payment gateway (UPI, cards, netbanking, wallets, EMI and pay-later), payment links, subscriptions and eNACH, split payments, virtual-account collections, payouts, card terminals, UPI soundboxes and cross-border collections, alongside sector software for schools, housing societies, temples, real estate and lenders. The operating company, Easebuzz Private Limited, was incorporated in December 2014 and launched its service in 2016. The Reserve Bank of India's list of authorised payment system operators shows it holding payment aggregator authorisation for online payments (dated 10 February 2025), plus physical and inward-and-outward cross-border payments. Easebuzz is for Indian businesses only: merchants are settled in rupees, including on foreign payments. It publishes no per-transaction rates. Its pricing page says pricing is customised and shared by email after you sign the agreement. GST is charged on its fees. The pricing page promises settlement one working day after the transaction, but the published terms allow up to three working days. Easebuzz reports ₹723 crore of FY26 revenue and a ₹11.15 crore profit after tax, more than 3 lakh merchants and close to US$50 billion in annual payment volume, and says it has been profitable every year. Its Trustpilot profile is small and mostly negative, and merchant accounts on its platform have been caught up in two fraud investigations, an Enforcement Directorate funds freeze in 2022 and a Delhi Police probe in 2024, neither of which has produced a finding against Easebuzz that we could find.

Comgate

Platform / Acquirer
B

Comgate is a Czech payment institution, licensed and supervised by the Czech National Bank, that sells an online payment gateway for e-shops and card terminals for shops and restaurants. Its legal entity is Comgate a.s., registered in Hradec Králové, with a second office in Prague. It is also a Visa and Mastercard card acquirer, so for most merchants the payment contract is signed directly with Comgate rather than a bank. As of October 2026 it publishes full price lists in Czech crowns (and euro lists for Slovakia). On the Easy plan you pay a flat 1% on EU consumer cards and 2% on other cards. On the Profi plan you pay 0.67% + CZK 1 on EU consumer cards, with higher rates for business and non-EU cards. New merchants get introductory rates for three months, and first-time card merchants can use a Start plan that is free up to CZK 50,000 a month for six months. The gateway's CZK 100 monthly fee is waived above CZK 100,000 of monthly volume. Payouts go out every working day, usually the day after the purchase. The contract has no fixed term and can be ended on two months' notice with no fee. Comgate signs merchants based in the Czech Republic and Slovakia; businesses elsewhere are assessed case by case. It accepts Visa and Mastercard, not American Express. Independent review data is thin: Firmy.cz shows 3.3 out of 5 from 57 ratings, and we found no regulatory enforcement naming the company.

Cielo

Platform / Acquirer
B

Cielo is one of Brazil's two largest card acquirers, based in Barueri, São Paulo, and it serves Brazilian businesses only. It was incorporated in 1995 and traded as VisaNet until it was renamed Cielo (announced in November 2009; some sources date the formal change to July 2010). Banco do Brasil and Bradesco control it, directly and through companies they jointly own, and took it off the B3 stock exchange in August 2024. Cielo signs the merchant agreement itself and sells card machines (maquininhas), tap-to-phone, payment links and e-commerce APIs. As of October 2026 its plans page lists two published plans. The Aluguel rental plan, for registered companies (CNPJ), charges 1.19% on debit and 3.45% on one-payment credit. The terminal is free in any month your card sales reach R$15,000; otherwise it costs R$99.90 a month. The Comodato plan, open to individuals too, costs a one-off R$238.80 (or 12 payments of R$19.90) and charges 1.90% debit and 4.30% credit. Both plans pay out in up to one day, subject to eligibility. Instalment sales cost much more: up to 14.79% (Aluguel) or 19.00% (Comodato) for 12 instalments. The agreement has no fixed term and either side can end it on 30 days' written notice without penalty. Cielo holds Reclame Aqui's top RA1000 rating, but improper charges are the problem tagged on 52.9% of the complaints it classifies.

Buckaroo

Payfac / Aggregator
B-

Buckaroo is a Dutch payment service provider based in Utrecht, which says it was founded in 2005. It is majority-owned by the French private equity firm Keensight Capital, which agreed to buy its stake in December 2021. It is licensed by De Nederlandsche Bank as a payment institution and sells online payments, card terminals and Tap to Pay on Android to businesses in the Netherlands, Belgium and Luxembourg. The merchant contract is with Buckaroo itself. Depending on the payment method, Buckaroo acts as the acquirer, as a processor for another acquirer, or as a payment facilitator signing cards up as the acquirer's agent. Customer money is held by a separate foundation, Stichting Derdengelden Buckaroo. Prices are published and exclude VAT. As of October 2026, online iDEAL by Wero costs €0.30 per payment, or less in a monthly bundle from €4.99. EU consumer cards online start at 1.80% + €0.25. In store, on the Dutch tariff, a domestic debit card payment costs €0.12, or €0.063 to €0.095 in a monthly bundle. Terminals cost €169 to €490 to buy or €19.65 to €44.50 a month to lease. Online payouts are weekly by default and terminal takings are paid out every working day. Buckaroo says it serves more than 55,000 businesses. As of 26 October 2026 its Trustpilot score is 2.8, with recent complaints about locked accounts and slow support. The terms favour Buckaroo: it can charge the rest of the first year's subscription fees if you leave early, hold a rolling reserve at its discretion, and raise prices once a year.

Alma

BNPL Network
B

Alma is a French buy-now-pay-later provider. It lets a merchant's customers pay in 2, 3 or 4 instalments, 15 or 30 days later, or over up to 12 months, online and in store. Alma lends to the shopper and takes on the risk of non-payment, and the merchant is paid the full basket less a commission. Alma SAS was registered in April 2018 by Louis Chatriot and Guillaume Desloges and is based in Neuilly-sur-Seine, near Paris. The French regulator, the ACPR, has authorised it as both a payment institution and a financing company since May 2021. As of October 2026 its French price list charges merchants 3.6% for 2 instalments, 3.8% for 3 and 4.8% for 4, plus VAT. Pay-later plans cost 4.2% (15 days) or 4.6% (30 days). There is no monthly or setup fee, and part of the cost can be passed to shoppers within legal caps. Plans of 10 or 12 instalments are priced on quote. Alma's help centre says payouts generally arrive 7 to 14 days after the sale, while its merchant terms say within seven days of the transaction being confirmed. The merchant contract has no fixed term, but either side must give three months' notice to end it. For 2025, Alma reported €2.5 billion of business volume and its first positive net result. It says 23,000 merchants use it, and consumers rate it 4.8 on Trustpilot. Complaints centre on declined applications, refunds and hard-to-reach support.

PayTR

Payfac / Aggregator
B-

PayTR is a Turkish payment and e-money institution, licensed by the Central Bank of the Republic of Turkey (TCMB). It was founded in 2009 and has its head office in İzmir, with an office in Istanbul. Its main product is a virtual POS (sanal POS) for online shops. A merchant signs one contract with PayTR and can then take cards from all Turkish banks, including instalment sales on the major bank card programmes. PayTR also offers payment links, a marketplace split-payment product, subscriptions, physical and phone-based POS, bank-transfer tracking and carrier billing. Pricing is mostly quote-only. As of October 2026, the only rate PayTR publishes for its standard service is a headline rate starting at 2.19% for single-payment card sales paid out after seven days. Your actual rate and payout term are set in a personal offer, and a longer payout term buys a lower rate. There is no setup, monthly or annual fee. In June 2021 the Competition Authority cleared the acquisition of sole control of PayTR by a company controlled by private equity firm Actera; press reports put the stake at 60%. PayTR says it serves more than 200,000 merchants. Complaint-site ratings are weak: 49 out of 100 on Şikayetvar, the main Turkish complaints platform, as of October 2026. PayTR is for businesses selling in Turkey only.

GoPay

Payfac / Aggregator
B-

GoPay is an online payment gateway for e-shops in the Czech Republic and Slovakia, based in České Budějovice. Worldline bought a 53% stake in 2020 and, according to the Czech company register, became sole owner in October 2022. Since 1 April 2025 GoPay has operated as GoPay Czech, the Czech branch of Worldline NV of Belgium, and is licensed by the National Bank of Belgium as a payment institution. As of October 2026 its pricing page offers two plans for new merchants. Both charge a flat 0.95% per card, bank-transfer or QR payment with no fixed fee, after a free introductory period. The Growth plan also has a CZK 80 monthly fee in any month with CZK 50,000 or less in volume. Settlement to your bank costs CZK 10, a chargeback CZK 990 and a refund CZK 5. Your plan price is written into your registration form, and GoPay's terms say an individual agreement overrides its general fee schedule. That schedule, in a version effective 1 November 2026, lists much higher default card fees of about 2.15% to 2.30% + CZK 3 and applies to anything your form does not set. GoPay offers more than 50 payment methods, including Czech bank buttons, QR payments, Apple Pay, Google Pay, PayPal and pay-later options. It says 19,823 merchants use it and that it handled CZK 98.7 billion in 2024. There is no fixed contract term and no cancellation fee. However, the terms let GoPay set reserves at its own discretion and end the contract within three months of signing without giving a reason. Its Trustpilot rating is poor, though from only 26 reviews.

Givelify

Payfac / Aggregator
B

Givelify is a mobile and online giving app for US churches and nonprofits, run by Givelify LLC from Indianapolis. Donors give by card through a free app or a web giving page. The organization pays nothing to sign up, no monthly fee and no contract. As of October 2026 Givelify takes 2.9% + $0.30 from each Visa, Mastercard and Discover gift and 3.5% + $0.30 from each American Express gift. The rest is deposited the next business day for gifts made before 9 p.m. Eastern. Givelify's terms describe it as a payment facilitator: each organization is a sub-merchant on Givelify's account with Worldpay, and only organizations expected to take more than $1 million a year in card gifts sign Worldpay's sub-merchant agreement directly. The price is simple but card-only. Givelify publishes no bank-transfer (ACH) giving option, so every gift pays the card rate, and a fee-cover option exists in the terms but is off by default. Ratings are strong: 4.9 stars from about 101,800 ratings on the App Store and about 44,100 on Google Play, and an A+ from the BBB with no complaints in three years. In 2016 Pennsylvania's banking regulator fined Givelify $176,000 for unlicensed money transmission. A state appeals court reversed that order in 2019.
