What payment provider is allowing payments without accessing the customers current funds? With a CC, you can charge $1000 with only $100 in your bank account. That is not something you can do with ACH, check, cash, etc. Pay Now Pay Later providers like Affirm would also allow this, but I'm not sure what that looks like from a merchant POV

Oh ok so you can’t pay with money you don’t have. I wish that cost wasn’t socialized.
