Customers don't need to know which payment gateway we are using. It's not useful information to them. If a client paid their invoice by credit card, then it should say credit card in the payment mode section. It doesn't look good to see payment mode as Authorize.net, stripe, square, etc. Keeping PayPal as PayPal, Cash as cash. But the major payment gateways should all say mode is credit card. I hate it when our customers call us and say I don't have an authorize.net credit card why does it say that?
