I have a client who has paid three times for one invoice (£288 x 3 for invoice# 1950). Rather than hold the money on their account, the client wants it paid back, which I have done once so far.
I have tried assigning the overpayment to the client’s account and then refunding it to them, but I have to allocate it to an invoice, which then shows it as ‘refunded’ - which is not true.
