What to Do When an Invoice Is Overdue

First verify the due date, balance, recipient and payment record. Resend the invoice with a factual reminder, ask whether anything blocks payment, record the response and follow a consistent escalation schedule. Add fees or legal threats only when they are accurate and permitted.

Verify before contacting the customer

Check the contract, invoice date, due date, customer, purchase order, payments and credits. Confirm that the invoice reached the correct accounts-payable contact and that no dispute is already open.

An aging report prioritizes risk but cannot explain the cause. Treat a missing attachment, approval delay, quality dispute and refusal to pay as different problems.

Make every reminder easy to act on

Include one invoice number, balance, original due date, copy of the invoice and a payment method. Ask for payment or a specific status/date. Avoid vague messages that force the customer to search for the transaction.

Keep the tone proportional. Do not claim that a fee, collection step or legal filing has occurred unless it has and the statement is permitted.
