We authorized one of our vendors to charge our company credit card for 1 invoice. Erroneously, they charged the card for 2 invoices. The next day they issued a credit card credit for the amount of 1 of the invoices. I created a credit card credit but I'm unable to apply it to the invoice that was not meant to be paid. I'm not sure how to show the full payment, the refund of part of the payment, how to apply the credit to the paid invoice that was refunded, and show when we actually did pay the invoice later. If someone could guide me through this, I would appreciate it!
