Is there a way or some easy way to setup adding an additional 3% processing fee charge to people paying by credit card? We already notify people ahead of paying that we charge an additional 3% and on our website we have it setup to add on the 3%. But when we process cards via the phone app, I'm wondering if there is a quick way to add the additional 3%. I guess I could set it up as a tax but maybe others have an idea that is easier.
