Customer overpayment to credit
A customer deliberately overpaid us - they are happy for the rest to be kept to apply to future invoices - and I don't know what to do with the bank transaction in the "for review" tab, nor how to apply some of the payment to the outstanding invoice.
With other incoming transactions from the linked bank account I've been able to match them to invoices, but that isn't an option for me now, I don't really understand why not.
Ideally I would like to be able to allocate some of this payment to the outstanding invoice, and leave the balance as a credit on the customer's account ready to apply for future invoices.
How can I achieve any of this?
