Gateway Fees allows you to charge customers additional fees depending on the payment method used to complete a purchase. The extension allows you to set a flat and or percentage fee for any enabled payment gateway. For example, if you wish to pass the credit card processing fee onto your customers, you could add a 2.9% + 30¢ fee to all purchases made through Stripe, PayPal Pro, Braintree, Authorize.net, or any of the other payment gateways that support direct credit card processing.

The extension works with all payment gateways.
