If you wish to accept credit cards payments, set up one or more payment gateways. To set up a proper payment gateway, consider payment methods you want to offer to your customers. If you plan to process credit cards, add an on-site payment gateway. If you wish to rely on payment intermediary service when processing credit cards, add an off-site payment gateway. You also can allow your customers to choose between paying by credit card (and run those charges through your on-site payment gateway) or paying by PayPal - off-site payment gateway. For details on how to set up a payment gateway, see Setting Up Payment Gateways.
To add one of these gateways, you need a merchant account with a corresponding payment processing service. In addition, if you plan to store credit cards details in your database, you need to configure encryption in your system. For details on encryption configuration, see Setting Up Encryption.
Business Manager supports integration with several payment gateways. Most of the gateways allow for charge, pre-auth, finalize, void, and refund abilities through Business Manager. For the list of supported gateways, see Appendix D.
