Stripe is the best payment gateway for most businesses. It offers a developer-friendly API and support for all common global payment methods. Below, we cover eight solid payment gateway options for accepting online and in‑person payments, from simple checkout tools to enterprise‑grade platforms.

Here’s a rapid side‑by‑side look at the gateways covered, including pricing model, standout feature, and ideal use case.

1. Stripe

Best for: businesses that need a flexible developer toolkit and support for dozens of global payment methods.
Stripe handles online and in‑person payments, subscriptions, and complex billing logic through a clean API. It runs on web, iOS, and Android and integrates with hundreds of platforms. Standout feature: the composable API lets you build custom checkout flows that feel native to your product, not a third‑party redirect.

2. Braintree

Best for: teams that want PayPal’s ecosystem plus a full‑stack gateway with solid fraud tools.
Braintree merges credit cards, digital wallets (Apple Pay, Google Pay), and local payment methods under one integration. It includes Kount‑powered fraud protection and the ability to process PayPal payments natively. Standout feature: the drop‑in UI gives a polished checkout experience with minimal front‑end code.

3. Authorize.Net

Best for: smaller merchants and established businesses that want a predictable, Visa‑backed gateway with recurring billing.
The platform handles secure credit card and e‑check processing, offers a virtual terminal, and includes a simple customer information manager. It works well for companies that don’t need heavy coding. Standout feature: the automated recurring billing engine manages subscriptions without requiring a separate tool.

4. Adyen

Best for: enterprise and international brands that need a single platform for e‑commerce, mobile, and point‑of‑sale with direct acquiring.
Adyen acts as both gateway and acquirer, reducing cross‑border friction and often improving approval rates. It provides real‑time revenue insights and supports over 250 local payment methods. Standout feature: true end‑to‑end processing. Funds flow through Adyen’s own acquiring licenses, simplifying reconciliation.

5. Square

Best for: retailers, cafés, and service businesses that want one system for online and in‑person sales with no monthly fees.
Square includes free POS software, card readers, and an instant online store builder. Built‑in fraud monitoring, chargeback protection, and straightforward e‑commerce plug‑ins come standard. Standout feature: the hardware and software bundle, which means you sell at a counter or pop‑up with the same backend that runs your web store.

6. Razorpay

Best for: India‑based startups and businesses that need a developer‑friendly gateway covering UPI, cards, and digital wallets.
Razorpay accepts over 100 payment modes and also handles payouts, payment links, and automated reconciliations. Its API documentation is strong, and the pre‑built dashboard keeps operations simple. Standout feature: payment pages let you accept money without any code, while the API still gives full control to dev teams.

7. Checkout.com

Best for: data‑driven enterprise teams that want to optimise acceptance rates across multiple currencies and local payment methods.
Checkout.com combines cloud‑based processing with real‑time analytics and proprietary fraud detection. Its global acquiring network and unified pay‑in/pay‑out API reduce operational complexity. Standout feature: granular transaction dashboards let you adjust routing rules and spot performance dips immediately.

8. Mollie

Best for: European SMEs that need a simple integration to accept SEPA payments, iDEAL, Bancontact, and major cards.
Mollie’s no‑nonsense dashboard, transparent pricing, and localised checkout flows make it a popular choice across the Eurozone. One contract covers multiple European countries without separate paperwork. Standout feature: seamless iDEAL and Bancontact support works out of the box, making it the fastest path to accepting popular Benelux payment methods.

Frequently asked questions

What does a payment gateway actually do?

A payment gateway encrypts transaction data, passes it between the customer’s bank and the merchant’s bank, and returns an approval or decline message. It sits between a checkout form and the payment processor, securing card details in real time.

Which payment gateway is the cheapest?

Flat‑rate gateways like Stripe and Square often charge around 2.9% + 30¢ per transaction. Interchange‑plus pricing from Authorize.Net or Adyen can cost less for higher volumes, and Square’s no‑monthly‑fee model suits low‑transaction businesses.

Can I use one gateway for international sales?

Yes. Stripe, Adyen, and Checkout.com all support multiple currencies and local payment methods. Check whether the gateway offers direct currency conversion and local acquiring to reduce cross‑border fees.

How do payment gateways handle security?

Every gateway in this list meets PCI‑DSS requirements and tokenizes card data so sensitive information never hits your servers. Built‑in tools like 3D Secure and custom risk rules add extra layers of fraud protection.

The verdict

Stripe remains the strongest all‑rounder. Its API depth, global reach, and massive integration ecosystem fit solo founders and scaling teams equally well. Adyen is the runner‑up for enterprise merchants that need direct acquiring and a unified commerce platform. When in‑person sales matter as much as online revenue, Square is the go‑to pick thanks to its free POS software and hardware bundle.
