We have received a double payment for an invoice from a customer. The first payment was made via PayPal and incurred a transaction fee. The invoice was marked as paid by applying this payment. Subsequently a second payment was made directly to bank account.
How can this second payment be credited to the customer's account with an option to either apply it to a future invoice or to issue a refund?
We are waiting for the customer to advise which option they prefer. When I go into Sales -> Receive Payments, there is no open invoice to which the second payment can be applied and the system throws the following error:
"An unbalanced transaction may not be recorded"
One option is to debit bank account and credit a temporary asset account but we would prefer an option that shows the credit against the customer's account rather than having it floating on the balance sheet.
