Customer overpaid how do I handle this
I have a customer that pays £72 a month, one month they accidentally paid 10 x too much but said to leave it on the system so that the next 9 payments are covered, I just am not sure how to match the invoices to this amount as the are issued.
So at the moment I have the £720 payment sitting in my bank transactions, If I try to match one or two of the £72 it says something isnt right (because its not the full amount), so If I make a credit note for the overpayment I can't see how I then apply the invoices to that credit note, the only option next to the invoice is to receive payment but this doesnt seem to apply it to the credit note
