Suggest you build your payment method to work with cs-cart as all other payment methods. You can do whatever you want in it. It's just the admin and configuraiton details that are separate. You'd then be able to use the payment surcharge related to your payment method and have it handle it for you.



Look at other payment methods. Some are pretty simple examples.
