Pay Methods are payment methods that belong to a client, like credit cards or bank accounts. They can apply to orders and invoices.

Payment gateways allow you to accept payments of many types in WHMCS. You can use one of WHMCS's many supported gateway modules or create your own.

WHMCS includes several supported payment gateway modules for accepting payments through PayPal®, including the new PayPal Payments gateway.
