Client received an overpayment of a few thousand pounds from a regular customer over a year ago.
This was overlooked until just a few months ago, at which point the client contacted the customer and has been trying to arrange repayment since - the customer has been back and forth regarding the original invoice as there is a little confusion about whether the amount invoiced was correct. There is no dispute though.
I have no doubt at all that there has been no dishonesty - the client never had any intention to retain the monies or hide the overpayment from the customer.
Are there any AML issues?
