Erroneous credit balance showing on customer account
We had a customer that forgot to pay be check for a service appointment. We went to the credit card on file to account for the invoice. On the next service appt, she paid double to account for the previous appt. Thus, she paid 3 times for 2 appts (1 CC and 2 checks). We appropriately issued a refund on her CC and attributed that refund to her account but the account still shows a credit of 1 appt. I know I could create a fictitious invoice to offset the credit but there has to be a more appropriate way to bring the balance to $0.
Thank you.
