Before following up on an unpaid invoice, double-check that the work was completed, your invoice details are correct and the money has not arrived. Check any agreed payment terms; clients sometimes use different banking cut-off times.
For a first reminder, be friendly. State the invoice number, amount and original due date, then ask whether the customer needs anything to process payment. Keep the message short and offer an easy reply path.
If the invoice remains unpaid, send a second message later with a clearer request for a payment date. Keep records of communications, avoid sending repeated messages the same day, and seek local legal or accounting advice before considering formal collections. ZUMIP enforces at most one email reminder per invoice in 24 hours.
