Just to verify - to give a credit back to a customer on their credit card if it is an open credit - you have to do a negative cash payment and do the credit card manually in SPS, right? Has anyone ever heard an explanation of why you can't do negative payments in Cash Receipts for CC payments?

You are correct. I was told it was to protect integrity of the company. To minimize ""fraud"".

My understanding is you can provided it's the same card used to pay the invoice. You cannot credit back to a different card.

This is the case where the client already has a credit on account and wants it back now on their credit card rather than leaving it as a credit. You can't do a negative CC payment to get rid of it - have to do a cash negative payment and go do the CC manually.
