# Gateway accounts

A [merchant account](/docs/glossary#merchant-account) is a bank account that enables a business to receive payments. A [payment gateway](/docs/glossary#payment-gateway) is a service which enables a business to receive payments from customers to their merchant bank account. A [payment method](/docs/glossary#payment-method) is a means of making a payment, for example a card payment.
