Best Merchant Services in 2026

Helcim sells merchant services on interchange-plus pricing with no monthly account fee, and it publishes its markups by volume tier rather than quoting each merchant individually. That transparency is unusual among interchange-plus providers and is the reason it ranks first here. Helcim's own site blocked automated access during research, so figures come from NerdWallet's review dated 5 March 2026.

For up to $50,000 in monthly card volume, the markup is 0.40% + 8¢ in person and 0.50% + 25¢ for online and keyed payments; between $50,000 and $100,000 it falls to 0.35% + 7¢ and 0.45% + 20¢, and it continues to fall at higher tiers, applied automatically. ACH costs 0.5% + 25¢, capped at $6. Hardware is sold outright: $199 for a card reader and $349 for a smart terminal with a printer. NerdWallet's reported drawbacks are deposits of up to two business days, no full countertop POS for restaurants, and user reports of abrupt account closures under terms that allow cancellation without notice.

Square, the seller business of Block, Inc., operates as a payment facilitator for small merchants. Merchants are boarded under Square's own account, so they can start accepting cards almost immediately without a separate merchant-account application. In the third quarter of 2026 Square handled US$76.4 billion of gross payment volume.

Square publishes all its US rates. On the free plan in-person transactions cost 2.6% + 15¢, online and invoice payments 3.3% + 30¢, API payments 2.9% + 30¢ and keyed transactions 3.5% + 15¢. The Plus and Premium software plans lower in-person pricing to 2.5% + 15¢ and 2.4% + 15¢ and invoice pricing to 2.9% + 30¢. ACH invoices cost 1% with a $1 minimum. As with all aggregated models, the trade-off for instant onboarding is that the provider can hold funds or close accounts after risk review, and the flat rate becomes expensive relative to interchange-plus as volume grows.

Clover is Fiserv's point-of-sale platform, sold together with Fiserv merchant processing. Fiserv's Merchant Solutions segment, which includes Clover, reported revenue of US$2.52 billion in the third quarter of 2026, down 3%, with the chief executive describing Clover's underlying growth as consistent. Clover's attraction is its line of dedicated terminals, from the Clover Go mobile reader to countertop Station systems, with software plans tailored to retail, dining and services.

NerdWallet's review, updated 20 May 2026 and based on Fiserv as the processor, lists in-person rates of 2.3% + 10¢ on most dining and Standard/Advanced plans, 2.5% + 10¢ on Home and Field Services Standard and 2.6% + 10¢ on Basic plans, with 3.5% + 10¢ for online and keyed payments. Software costs from $0 to $129.85 per month. Software is month-to-month, but processing may require a long-term contract and hardware promotions require three years.

Chase Payment Solutions is the merchant-services arm of JPMorgan Chase for small and mid-sized businesses. It supplies the Chase POS app, a card reader, the Chase POS Terminal and standalone terminals, Tap to Pay on phones, an online payment gateway with e-commerce integrations, invoicing and a virtual terminal. It also integrates with TouchBistro, NCR Voyix and Authorize.net.

Its published flat rates are 2.6% + 10¢ for tapped, dipped or swiped cards, 3.5% + 15¢ for keyed payments and payment links, and 2.9% + 25¢ for online orders. Funds can arrive as soon as the same day at no extra cost when settled into a Chase Business Complete Banking account, and that account's monthly service fee can be waived for businesses processing more than $2,000 a month in card payments. The combination of bank account and merchant account in one relationship is the main reason to choose Chase over a fintech provider.

Stax charges a monthly subscription in place of a percentage markup, so the merchant pays the card networks' interchange cost plus a small fixed fee per transaction. NerdWallet's review, updated 7 August 2026, is the source for these figures because Stax's site blocked automated access.

Subscriptions are $99 a month below $150,000 of annual processing, $139 between $150,000 and $250,000, and $199 or more above that. The per-transaction fee is 8¢ in person and 15¢ for keyed and online payments; ACH costs 1% up to $10. A $10 monthly PCI compliance fee applies. NerdWallet considers Stax uneconomic for businesses processing under about $10,000 a month, notes weekday-only support hours and a longer application for dedicated merchant accounts, and reports user complaints about costs rising over time. Stax also owns Payment Depot, which serves merchants who prefer interchange-plus without a subscription.

Payment Depot is a US merchant-services provider owned by Stax. Its earlier membership plans have been replaced, according to NerdWallet's 12 January 2026 review, by interchange-plus pricing with a markup of 0.2% to 1.95% and no subscription. Payment Depot's own pricing page blocked automated access during research.

Merchants pay a $10 monthly PCI compliance fee; there are no long-term contracts or termination fees. Hardware is bought outright, from $125 for a SwipeSimple B350 reader to $2,195 for a Clover Station Duo. Support is available by phone, chat and email on weekdays from 8 a.m. to 6 p.m. Eastern. NerdWallet notes that accounting integrations require third-party apps and some e-commerce integrations may cost extra. Because the markup is set per merchant within a wide range, Payment Depot is best evaluated by requesting a written quote and comparing it with Helcim's published tiers.

Stripe provides merchant services primarily through software: businesses integrate its APIs or hosted pages and are boarded under Stripe's account. It also sells Stripe Terminal readers for in-person payments. Standard US pricing has no setup or monthly fees.

Domestic online cards cost 2.9% + 30¢, with 1.5% added for international cards and 1% for currency conversion; in-person Terminal payments cost 2.7% + 5¢. ACH Direct Debit costs 0.8% capped at $5; disputes cost $15, with a further $15 to contest that is refunded if the merchant wins. Optional services include Radar fraud screening from 5¢ per screened transaction and Billing at 0.7% of billing volume. Stripe suits businesses with development resources or a platform that embeds it; companies wanting a turnkey retail POS or a bank relationship usually look elsewhere. Large merchants can negotiate custom pricing, which Stripe does not publish.

Toast provides POS software, hardware and payment processing for restaurants, together with online ordering, payroll and capital. It reported about 189,000 locations and US$61.8 billion of gross payment volume in the third quarter of 2026.

According to NerdWallet's review updated 6 August 2026, card-present payments cost 2.49% + 15¢ and card-not-present 3.50% + 15¢ when hardware is bought upfront; pay-as-you-go plans that remove upfront hardware cost 3.09% to 3.69% + 15¢. Software plans run from a $0 Starter Kit to the $69-a-month Point of Sale plan and quote-based custom plans. Installation costs $800 to $1,000 per day, and contracts usually run two to three years. Toast's merchant services are therefore inseparable from its software, and businesses outside food service are rarely a fit.

Authorize.net is a US payment gateway that describes itself as powered by Visa's payments ecosystem. It can be bought as an all-in-one package that includes a merchant account, or as a gateway that connects to a merchant account from another provider, which makes it a common choice for businesses that want to keep their existing bank processor while adding online payments.

Every plan costs $25 a month with no setup fee and no early-termination fee. The all-in-one plan charges 2.9% + 30¢ per transaction, subject to eligibility. The gateway-only plan charges 10¢ per transaction plus a 10¢ daily batch fee, and adding eCheck costs 0.75% per eCheck transaction, with a $25 eCheck chargeback fee. Features include a virtual terminal, recurring billing, Account Updater, Advanced Fraud Detection, invoicing, mobile and Tap to Pay acceptance, and 24/7 support. The $25 monthly fee makes it more expensive than no-fee facilitators for very small merchants.

Adyen is a financial technology platform that acts as gateway, processor and acquirer on one system for online, in-store and platform payments. It reported net revenue of €738.1 million in the third quarter of 2026, up 23%, on processed volume of €451.1 billion, up 30%, and guided to 21% to 23% constant-currency net revenue growth for 2026.

Adyen publishes its pricing structure: a fixed processing fee per transaction plus a fee determined by the payment method, with no setup or monthly fees. In North America the processing fee shown is US$0.13, and the major card schemes are priced at interchange++ plus 0.60%. Interchange++ separates interchange and scheme fees from Adyen's markup, which large merchants prefer for cost auditing. Adyen generally serves larger merchants that can integrate its API; it is not designed as a self-service option for very small businesses, and its per-transaction fixed fee is additive to the payment-method fee.

Worldpay is a merchant acquirer that has been part of Global Payments Inc., which bought it from FIS and private-equity firm GTCR while selling its own Issuer Solutions business to FIS. Global Payments, headquartered in Atlanta, describes the combined business as a pure-play commerce solutions provider serving more than six million merchant locations, processing about US$3.7 trillion of payment volume and roughly 94 billion transactions a year in more than 175 countries. Worldpay.com pages now redirect to Global Payments' site.

The combined company organises sales into Enterprise, SMB, and Integrated and Platforms channels and plans more than US$1 billion a year of investment in product development. Pricing is individually quoted and was not published on the pages consulted. Merchants evaluating Worldpay during the integration period should confirm which platform, contract entity and support model will apply after migration.

Elavon is a US merchant-services provider whose careers pages are hosted by U.S. Bank. Its current product range includes Talech mobile payments, in-person and contactless terminals, e-commerce plans, payment gateways and optimisation, PCI and security tools, reporting, and Quick Capital financing provided through Liberis. CenPOS technology is referenced for the automotive sector.

Elavon states that, as of May 2025, 91% of its merchants were funded within two business days. Its site describes e-commerce "plans" but does not publish processing rates, so pricing is quote-based. Elavon suits merchants who prefer a bank-affiliated acquirer with phone support and terminals, but the absence of published rates makes comparison with Helcim, Square or Stripe dependent on a written quote.
