AdPress can support multiple payment gateways at checkout. From your Admin panel, you can select which payment gateways are enabled. You can also select a default payment gateway, which will be selected on Checkout.
Enter the credentials and settings for each gateway separately. More gateways are available as free or paid add-ons.
At checkout, the user will be able to select his preferred payment method. The Default payment gateway will be selected when the page is loaded.
