Past Due Invoice Reminder Examples for Every Stage
The longer an invoice sits unpaid, the clearer your follow-up should become. These examples give you a professional starting point without sounding hostile or vague.
When an invoice is just a few days late
Start with a courteous reminder. Late payment can be caused by a missed email, an approval delay, or a customer simply forgetting. Keep the message short and make payment easy.
When the invoice is one to two weeks late
At this point, ask for a concrete update. You do not need aggressive language, but you should clearly state that the invoice remains unpaid and ask when payment will be made.
When the invoice is 30 days or more late
A firmer message is appropriate. Restate the balance, reference prior follow-up, and request prompt payment or a reply explaining the delay.
Keep every message factual
- Invoice number
- Outstanding balance
- Original due date
- Payment instructions or link
- A specific request for payment or status
Professional wording you can adapt
