Customer overpaid and we processed a customer refund.  one Week later the customer caught the overpayment and took it from a check with multiple invoices.  Problem is EVO will not let me reverse the invoice.  First one we did, and accidentally saved without invoice number entered.  Now I just have this payable in my system that I cannot edit or reverse!!!  Went to test company and tried to issue a credit, write a check etc and everything showed correct, except the money is back in ap to be paid.  Also, since there is no invoice number, this invoice does not show up on reports.
