Final notice for an unpaid invoice

Before you send a final notice

• Make sure you've sent at least one earlier reminder, ideally two.
• Check the invoice is correct and was sent to the right person.
• Decide what you'll actually do if it isn't paid, and only say that. Don't threaten anything you won't follow through on.

Final notice template

Hi [Client name],

This is a final reminder about invoice [number] for [amount]. It is [X] days past due, and I still don't have a record of payment.

Please pay within 7 days, by [deadline date], or reply today with a firm date. I'll pause further work on the account until this is settled.

I've attached the invoice again for reference.

Regards,
[Your name]

A shorter version

Hi [Client name],

I'm writing one last time about invoice [number] for [amount], now [X] days past due.

Please pay by [deadline date] or reply with the exact date payment will be sent. If I don't hear back, I'll pause additional work until the balance is cleared.

Regards,

What to include

• The words "final reminder" or "final notice" in the subject line.
• The invoice number, amount, and how many days late it is.
• A specific deadline date, not "soon".
• The one next step you'll take, stated calmly.
