The best online payment services

Online payment services let businesses accept cards, wallets and bank payments on websites, apps and in person, then handle security, payouts and reporting. We compared official fee pages, feature pages and public reviews to find services that still serve businesses well in October 2026. Fees vary by transaction type, region and volume, so check the current fee schedule for your business before choosing.

#1

Stripe

Ideal for: Most online businesses

Stripe website
stripe.com homepage

Stripe is the default payment service for many online businesses, thanks to its developer friendly APIs, clear documentation and support for cards, wallets, bank debits and local payment methods in many countries. Its dashboard, invoicing, subscriptions and fraud tools cover most online selling needs, and its global reach suits businesses that sell internationally. That combination makes Stripe the safest first choice for a new online business.

Stripe charges per transaction, with standard US card fees commonly cited around 2.9 percent plus 30 cents, though exact fees vary by method and region, so check the current pricing page. Account holds and reserves can affect high risk businesses, and support for small accounts can be slow, but for most legitimate online businesses, Stripe offers the best balance of tools, reach and reliability.

The good and the bad
  • Excellent developer tools and docs
  • Global payments
  • Many payment methods
  • Fees per transaction
  • Account holds for risky businesses
  • Support can be slow for small accounts

#2

PayPal

Ideal for: Buyer trust and checkout

PayPal is the most recognised online payment brand, and offering it at checkout can increase conversions, since many buyers already have a PayPal account and trust its buyer protection. It supports cards, PayPal balance, Venmo in the US and Pay Later options, which gives buyers flexibility. Seller protection covers eligible transactions, though terms and exclusions apply.

Fees are per transaction and vary by type, with standard US fees commonly around 2.9 percent plus a fixed fee, plus extra for international or currency conversion, so check the current schedule. Account holds, reserves and dispute handling frustrate some sellers, especially for digital goods, but for buyer trust and easy checkout, PayPal remains essential for many sellers.

The good and the bad
  • High buyer trust
  • Easy checkout
  • Buyer and seller protection programmes
  • Fees per transaction
  • Account holds and disputes
  • Higher fees for some transactions
Square logo
#3

Square

Ideal for: In person plus online

Square website
squareup.com homepage

Square suits businesses that sell both in person and online, since its card readers, point of sale app and online store work together with one account and dashboard. A cafe, salon or market stall can take in person payments and sell online without separate systems, which simplifies accounting and inventory. Setup is easy, with no monthly fee for the basic point of sale app.

Transaction fees are similar to Stripe and PayPal for cards, with standard US in person and online rates varying by method, so check the current pricing. Online developer tools are less deep than Stripe's, so businesses that need complex subscriptions or marketplaces may prefer Stripe, but for omnichannel small businesses, Square is hard to beat.

The good and the bad
  • In person hardware plus online
  • Easy setup
  • Free point of sale app
  • Fees per transaction
  • Online features less deep than Stripe
  • Account holds possible
Shopify Payments logo
#4

Shopify Payments

Ideal for: Shopify stores

Shopify Payments is built into Shopify, so store owners can accept cards without a third party gateway and without paying Shopify's extra transaction fees that apply when using an external provider. Setup is quick, payouts go to your bank, and Shop Pay, Apple Pay and Google Pay are included, which can improve checkout conversion. That integration makes Shopify Payments the obvious choice for Shopify stores.

It only works on Shopify, so businesses on other platforms need Stripe, PayPal or another gateway, and a Shopify subscription is required. Payout timing and available payment methods vary by region, so check Shopify's current terms for your country, but for Shopify sellers, Shopify Payments is the simplest and often cheapest option.

The good and the bad
  • Built into Shopify
  • No extra transaction fees on Shopify
  • Easy setup
  • Only for Shopify stores
  • Shopify subscription needed
  • Payout and region rules vary
Adyen logo
#5

Adyen

Ideal for: Global enterprises

Adyen is a global payment platform used by large enterprises and platforms, offering cards, wallets and local payment methods in many countries through one integration. Its unified commerce approach links online, in app and in store payments, which suits retailers with many channels and regions. Reporting, risk management and optimisation tools are enterprise grade.

Adyen is built for larger businesses, with pricing and minimums that reflect that focus, and setup is more complex than Stripe or Square for a small store. If you are a large or fast growing global business, Adyen is a top tier choice, but small businesses should start with Stripe, PayPal or Square.

The good and the bad
  • Global payments in one platform
  • Unified commerce
  • Strong enterprise features
  • Enterprise focus
  • Minimums and pricing for larger businesses
  • Complex setup
Authorize.net logo
#6

Authorize.net

Ideal for: Established gateways

Authorize.net is a long established payment gateway that connects a website to a merchant account, offering a virtual terminal, recurring billing and fraud tools. It suits businesses that already have a merchant account through a bank or processor and want a reliable gateway with broad compatibility. Its longevity means many e-commerce platforms and developers support it.

Many plans include a monthly gateway fee plus transaction fees, which can make Authorize.net more expensive than Stripe for small volumes, and its interface feels dated beside modern dashboards. For businesses with an existing merchant account, Authorize.net remains a dependable gateway, but new businesses usually prefer Stripe's simpler pricing.

The good and the bad
  • Long established gateway
  • Works with many merchant accounts
  • Virtual terminal
  • Monthly gateway fee in many plans
  • Interface feels dated
  • Setup more complex
Venmo (Business) logo
#7

Venmo (Business)

Ideal for: Social payments

Venmo, owned by PayPal, is popular with US consumers for peer to peer payments, and its business profiles let small sellers accept Venmo payments with a social, familiar checkout. That familiarity can increase conversions for US sellers targeting younger buyers, since many customers already have Venmo installed. Business payments are separate from personal payments, with fees and seller protections for eligible transactions.

Venmo is US only, so international sellers need another service, and business fees apply, so check the current business fee schedule. For US small sellers, especially in food, events and casual retail, Venmo is a useful additional payment option alongside PayPal and cards, not a replacement for a full gateway.

The good and the bad
  • Popular with US consumers
  • Social checkout
  • Easy for small sellers
  • US only
  • Business fees apply
  • Not for large or international businesses
Wise Business logo
#8

Wise Business

Ideal for: International payments

Wise Business is not a card checkout service, but it belongs here for businesses that pay and receive internationally, since it offers multi currency accounts, low cost transfers and transparent exchange rates. Freelancers, agencies and e-commerce sellers who work across borders use Wise to hold balances in several currencies, pay suppliers abroad and receive payments with lower conversion costs than banks.

Wise does not replace Stripe or PayPal for retail checkout, since customers cannot pay by card through Wise at a store checkout. Use Wise alongside a checkout gateway for international payouts and supplier payments, where its exchange rates and fees often beat traditional banks.

The good and the bad
  • Low cost international transfers
  • Multi currency accounts
  • Transparent exchange rates
  • Not a card checkout gateway
  • Business account features vary
  • Not for retail checkout

How we picked these

We compared official fee pages, feature pages and public reviews, and we only included services that still process online payments in October 2026. We favoured services with clear fee schedules, strong security, global or US reach and distinct strengths, from developer tools to in person hardware and international transfers, since no single service covers every payment need.

How to choose an online payment service

Start with how and where you sell. Online only businesses should shortlist Stripe, Shopify stores should use Shopify Payments, in person plus online businesses should look at Square, and businesses that value buyer trust should also offer PayPal. International businesses should add Wise Business for payouts and supplier payments, even if checkout runs through Stripe.

Compare total fees for your average order value, including percentage, fixed fee, international, currency conversion and chargeback costs, since a low percentage with a high fixed fee hurts small orders. Check payout timing, reserve policies, fraud tools and support quality, and test checkout on mobile, since most buyers now pay on phones. Finally, keep payment security in mind: use a PCI compliant provider, enable fraud filters and never store card details yourself.
