Question: How can a client over pay and leave the remainder as a credit?
The easiest way to keep the credit for overpayment on a client account is to enter in the payment as follows.
For example the invoice the client is paying totals $15.00. They want to pay $20.00 and leave the $5.00 as a credit on the account.
On the checkout screen you would enter in the payment amount as 20.00, and enter the cash received as 20.00 and process the payment.
The system will apply the $15.00 to the invoice and the remainder of $5.00 will appear as a credit on the client account.
You will see the following message when you process the payment.
