Use aging for visibility
Place the remaining unpaid balance in the bucket that matches how long it has been overdue. This starter worksheet uses Current / Not Due, 1-30 days, 31-60 days and 61+ days for a simple manual review.
Age the remaining balance, not the original amount after partial payment
If a client has paid part of an invoice, confirm the remaining balance first. The worksheet is meant to show the amount still exposed, while the payment history stays in your source records.
Aging is not the action
An older bucket helps you prioritize review, but it does not decide what message, fee or collection step is appropriate.
