Can I credit an invoice that was already paid? and if so, what happen to the invoice and the payment? do they both come back into my A/R
this is what happened.
1. a customer sent us a prepaid payment
2. when they billed the invoice (they did it in the wrong month). however, the payment (because it was prepaid) was applied to this invoice.
3. Now, I want to enter the invoice in the correct month. but for that, i need to reverse/credit the wrong invoice and of course, i then need to apply the money that the customer already sent us.
please let me know how to handle this.
