We are using Reckon Enterprise 2017. I have recently received payment for a number of invoices from a customer, however they overpaid by $203.50 and I opted to keep the credit for use later. I have now received another payment from the company which I am trying to receipt and to take up the overpayment. However, when I enter the details, the credit is not showing when I try to apply it - any ideas? Thank you.
