Just updated the newest program and my past due accounts were reset to $0.00 unless the invoice was in the 30 days . Why? I have a few customers that have terms beyond , also a few clients that have outstanding balances that had their overages removed to $0. as they had gone beyond their given payment.
You have not provided enough information to answer your question. You will need to look at individual invoices. The answer could depend on how long it has been since you updated. For example, changes have been made to the program as to how over paid invoices are recorded. Post a screenshot of an invoice that demonstrates this problem.
