Copy-ready wording

Three overdue-invoice email templates.

Start friendly, become specific, and keep every message easy to act on. Replace every bracketed field and check the amount before sending.

Reviewed 20 August 2026 ยท Administrative templates, not legal notices

1. Friendly reminder

Use this when the invoice has just become overdue and there has been no previous reminder.

Subject: Reminder: invoice [number] is overdue Hi [name], I hope you are well. I am following up on invoice [number] for [amount], which was due on [date]. Please arrange payment, or let me know today if anything is preventing it from being processed. I have attached the invoice again for convenience. Kind regards, [your name]

2. Firm follow-up

Use this after the first reminder has received no useful response.

Subject: Payment date required for invoice [number] Hi [name], Invoice [number] for [amount] remains unpaid following my reminder on [date]. Please confirm today when payment will be made. If there is a query preventing payment, send the details so it can be resolved. Otherwise, please arrange payment by [date]. Regards, [your name]

3. Final administrative notice

This is a final internal escalation message, not a substitute for a solicitor-approved letter before action.

Subject: Final payment follow-up: invoice [number] Hi [name], Invoice [number] for [amount], due on [date], remains unpaid despite reminders sent on [dates]. Please make payment by [final date] or provide full details of any dispute by that date. If neither is received, I will review the formal recovery options available and retain this correspondence as part of the invoice record. Regards, [your name]
