Companies that hold the acquiring relationship and run their own processing stack. Everyone further down this list ultimately settles on rails like these.
Ranked by grade, then by average category score. Equal grades share a position — where our evidence does not separate two providers, neither does this list.
Adyen is a global, enterprise-grade payments platform that unifies acquiring, processing, routing and risk management into a single stack for merchants with international and omnichannel needs.
Shift4 Payments is a full-service payment processor and POS provider specializing in integrated commerce solutions for restaurants, hospitality, retail, and enterprise merchants.
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.
A London-headquartered payment service provider and acquirer, founded in 2002 by its current chief executive Jonas Reynisson, that is unusual in this market for owning both halves of the stack. emerchantpay holds its own FCA authorisation as an electronic money institution (Reg. 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. Its US arm is in Boca Raton, but its licensing and scheme membership are European, so establish which entity is boarding you.
The US payments arm of Xplor Technologies, and the company you knew as Clearent until it dropped the name in July 2025. It is a straightforward mid-market acquirer with two things going for it that most of its peers do not have: interchange-plus is the default rather than the upsell, and next-day funding runs on an 11:00 p.m. Eastern cut-off, which is about as late as this industry gets. 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.
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.
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.
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.
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.
A London-headquartered, Israeli-founded fintech-as-a-service platform that sells collection, payouts and multi-currency accounts through one API. Its 2025 purchase of PayU's Latin America and Africa business for $610 million gave it direct local acquiring in six Latin American countries plus Nigeria and South Africa — genuinely hard-to-reach markets. It is built for platforms and marketplaces rather than small merchants, publishes almost no acquiring pricing, and its public merchant reviews are poor.
Moneris is Canada’s largest payment processor, providing point-of-sale systems, ecommerce payment gateways, and mobile payment solutions for businesses across Canada through a joint venture owned by Royal Bank of Canada and Bank of Montreal.
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.
Europe's largest listed payments company and, since March 2026, one that no longer sells to North American merchants at all — it sold its North American subsidiaries, including Bambora North America, to Shift4. What remains is a Paris-headquartered acquirer and processor serving roughly 1.2 million merchants and financial institutions across Europe with about 13,400 staff. 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. The underlying acquiring business is real and licensed; the governance record and the balance sheet are why this is not a B.
Carat from Fiserv is an enterprise-grade global commerce platform that orchestrates omnichannel payments, data intelligence, and customer experience solutions for the world's largest businesses, but hampered by opaque pricing, complex contracting, and a widespread customer service reputation that does not match its technological ambitions.
Bank of America Merchant Services is a large, bank-integrated payment processing solution ideal for existing BofA business checking customers who value brand stability, seamless funding, and broad payment acceptance though it lags behind fintech competitors on pricing transparency, modern integrations, and third-party review scores.
A capable global orchestration platform — published card rates in a handful of countries, local acquiring in 50 more, one integration for over 200 regions — carrying a 2024 FTC settlement for processing payments for a known scam, and now owned by Payroc.
One of the largest privately held US acquirers, rebranded from North American Bancard in 2024 — a rebrand that also reset its public review record. It publishes POS rates and says it does not require a long-term contract, but reviewers who have read its traditional merchant agreement report a three-year term with a liquidated-damages termination clause.
PNC Merchant Services is the card-acceptance arm of PNC Bank, and PNC describes it on its own site as an alliance between the bank and Fiserv — PNC owns the customer relationship and support, Fiserv provides the processing and the Clover hardware. It publishes flat rates, which most bank programmes do not: 2.60% plus $0.10 for a swiped, dipped or tapped card and 3.45% plus $0.15 for online, telephone or manually keyed transactions, with next-business-day funding on Visa, Mastercard, Discover and American Express when the money lands in a qualifying PNC business checking account. What it does not publish is the rest of the agreement — the monthly and annual account fees, the term length, and the liquidated-damages provision that applies if you leave early. That gap is not academic: in November 2021 PNC Merchant Services agreed to a settlement of up to $14.5 million to resolve two class actions brought by merchants over annual fees, early-termination fees and paper statement fees.
One of the largest acquirers in the world, bought by Global Payments in January 2026 and now being folded into that brand. Enormous reach, but small merchants still get a three-year contract, an auto-renewal clause and pricing that is never published.
The terminal company that became a payments company. Verifone has been making card-reading hardware since 1981 and is the device behind a very large share of the world's checkout counters, but the merchant-facing business it has assembled around that hardware — Verifone Payments acquiring, plus the 2Checkout platform it bought in 2020 — is a much weaker story. Its US BBB profile carries an F for failing to answer complaints, its own .com Trustpilot page sits at 1.5 out of 5, and no acquiring rate is published anywhere. The only prices Verifone publishes are 2Checkout's, and those are merchant-of-record rates for selling software, not merchant-account rates.
Wells Fargo Merchant Services is a division of one of the largest U.S. banks, offering credit and debit card processing, Clover POS systems, and e-commerce solutions to small and medium-sized businesses.
Global Payments Inc. is a Fortune 500 payments technology behemoth, processing trillions of dollars annually across 38 countries, offering massive scale and enterprise capabilities, but consistently criticized by small and mid-size merchants for opaque pricing, hidden fees, rigid contracts, poor customer support, and a significant history of legal actions.
Paysafe is a global payments technology platform that provides merchants and consumers with payment processing, digital wallet services, alternative payment methods, and secure transaction infrastructure.
Elavon is one of the world's largest payment processors, serving over 2 million merchant locations across 36 countries offering a comprehensive suite of enterprise payment solutions, but widely criticized by small and mid-size merchants.
