Payment reminder email templates
Most late payments are not refusals. They are forgotten invoices. A clear, polite sequence of reminders gets most of them paid.
The sequence
- Three days before the due date: a friendly heads-up.
- On the due date or the day after: a polite reminder.
- Seven to ten days overdue: a firmer reminder with a specific date.
- Twenty to thirty days overdue: a final notice that states the next step.
What every reminder includes
- Invoice number, amount and original due date.
- The invoice attached again, or a link to it.
- How to pay: bank details or payment link.
- One clear request and a date.
Template 1: friendly heads-up
Subject: Invoice 0142 due on Friday
Hi Sam, a quick note that invoice 0142 for 1,200 is due this Friday, December 11. I have attached it again for convenience. Thanks, and let me know if you need anything from me.
Template 2: polite reminder
Subject: Reminder: invoice 0142 is now due
Hi Sam, invoice 0142 for 1,200 was due yesterday. Could you confirm when payment will be sent? Payment details are on the attached invoice. Thank you.
Template 3: firmer reminder
Subject: Invoice 0142 is 10 days overdue
Hi Sam, invoice 0142 for 1,200 is now 10 days overdue. Please arrange payment by Monday, December 28, or let me know today if there is an issue with the invoice so we can sort it out.
Template 4: final notice
Subject: Final notice: invoice 0142
Hi Sam, despite my earlier reminders, invoice 0142 for 1,200 remains unpaid, now 25 days past due. Under our agreement, late payments [incur the late fee in clause X / pause further work]. Please pay by January 8 to avoid that step.
Only mention a late fee or a pause if your contract or terms actually include it. Rules on late fees and collection differ by country; check yours before escalating.
Tone that works
- Assume a mistake, not bad faith, until the third reminder.
- Keep it short. One request, one date.
- Use the same email thread so the history is visible.
- Pick up the phone after the second reminder for large invoices.
Prevent it next time
- Payment terms in the contract: due date, deposit, milestones and late payment. See the freelance contract template.
- Deposits for new clients and large projects.
- Invoice on delivery, not at the end of the month.
- Track due dates so reminders go out on time; see the freelance invoice tracker and the freelancer year-end checklist.
Keep a log
For each overdue invoice, note the date of every reminder and the client's reply. If you ever need to escalate, a clear log of polite reminders makes your position much stronger, and it helps you decide which clients need a deposit next time.
Set the reminder dates when you send the invoice, not when it becomes overdue. A tracker that flags due and overdue invoices makes the sequence automatic.
