Quick comparison table

These tools differ in checkout setup, payment methods, and support for international processing. Before choosing one, confirm its current pricing, regional availability, and integration requirements.

1. PayPal Checkout

Best for: Businesses seeking familiar payment options and flexible checkout choices.

PayPal Checkout offers hosted checkout as well as a more customizable setup. It supports PayPal, cards, and other payment methods, so customers can pay in familiar ways while businesses choose how much control they need over checkout.

For integrations, PayPal combines REST APIs with a JavaScript SDK. Development teams can use them to connect checkout to an existing site or build a more tailored payment flow. Check which payment methods and features are available for your location and setup.

2. Authorize.net

Best for: Businesses that need to accept payments online, in-store, and on mobile.

Authorize.net supports card payments, digital wallets, and eChecks across online, in-store, and mobile channels. It also offers recurring billing and fraud protection, which makes it a practical choice for businesses with needs beyond basic online card payments.

Its mix of payment channels and recurring billing stands out. Before choosing it, make sure its payment options and integrations fit your point-of-sale setup, website, and billing needs.

3. Checkout.com

Best for: Businesses processing online payments across multiple markets.

Checkout.com processes online card payments and local payment methods through a payments API. Local options can help businesses offer payment methods customers recognize in different markets. The API also provides a way to connect payment processing with a website or other systems.

One notable feature is support for more than 150 processing currencies. That range may suit businesses taking payments across borders, but currency support does not mean every payment method or service is available in every country. Confirm market coverage and integration requirements with the provider.

4. Cybersource Payments

Best for: Businesses seeking payment processing across channels through connections to processors and acquiring banks.

Cybersource Payments processes payments across channels through a gateway connected to processors and acquiring banks. Visa describes the service as offering global payment flexibility and real-time processing, which may matter to businesses handling payments in more than one market.

The gateway’s connections to processing and acquiring partners are its main feature. Available capabilities can depend on your location, setup, and provider relationships. Confirm which payment channels and processing features apply before comparing it with other options.

How we picked these tools

This roundup focuses on different payment needs rather than treating every gateway as interchangeable. We compared the channels each tool supports, its payment methods, recurring billing features, and integration options based on the available product information.

We also considered international processing where the details made a comparison possible. For example, Checkout.com specifies support for more than 150 processing currencies. The other descriptions mention broader channel or global capabilities but do not provide the same level of detail.

We did not rank providers by price because comparable pricing information was not available. Before choosing a tool, check current fees and terms, regional availability, and the technical requirements for connecting it to your website or payment systems.

Frequently asked questions

What does payment gateway software do?

Payment gateway software passes payment information between a customer, a business, and the systems that process a transaction. It’s part of the checkout process, whether a sale happens online, in a store, or on mobile.

What is the difference between hosted checkout and an API?

With hosted checkout, the provider supplies the checkout experience, so a business may have less to build itself. A customizable checkout or API integration offers more control over the payment flow but can require more development work.

What should I check before choosing a gateway?

For recurring payments or eChecks, confirm that the provider supports the payment type and billing setup you need. For international sales, check supported countries, local payment methods, and processing currencies. Ask each provider about transaction fees, settlement timing, and available fraud tools before committing.

The verdict

PayPal Checkout is the strongest overall pick for its hosted and customizable checkout, range of payment methods, and developer integration options. Authorize.net is a strong alternative for businesses that need recurring billing across online, in-store, and mobile channels. Checkout.com is a runner-up for international processing. The right choice still depends on your location, setup, and the provider’s current terms.
