Payment reminder email templates that get invoices paid (5 examples)

A payment reminder email is the cheapest collection tool you have. Written well, it resolves most late invoices before anyone has to pick up the phone. Written badly, it either gets ignored or sours the relationship. Below are five templates you can copy, organised by where the invoice is in its life.

The rules every reminder should follow

• Put the invoice number, amount and due date in the first two lines.
• Attach the invoice or link to it. Never make the client search.
• Ask one clear question or give one clear action.
• Stay neutral. Assume an administrative gap, not bad faith.
• Send it to the person who can approve payment, not just the original contact.

1. Friendly reminder (3 days before due)

Subject: Invoice #1042 due Friday. Body: Hi Sam, a quick note that invoice #1042 for $2,400 is due on Friday 10 October. The invoice is attached for convenience. If anything needs to change before it can be approved, let me know and I will sort it today.

2. Due-date reminder

Subject: Invoice #1042 is due today. Body: Hi Sam, invoice #1042 for $2,400 is due today. You can pay by bank transfer or card using the link in the attached invoice. Thanks for taking care of this.

3. First overdue reminder (3 to 7 days late)

Subject: Invoice #1042 is now overdue. Body: Hi Sam, our records show invoice #1042 for $2,400 was due on 10 October and is still open. Could you confirm whether it has been approved and when payment is scheduled? If it has already been paid, please send the remittance and I will update our records.

4. Second overdue reminder (14 days late)

Subject: Second reminder: invoice #1042, 14 days overdue. Body: Hi Sam, I have not yet received payment or a reply about invoice #1042 for $2,400. Who on your side approves supplier payments? I am happy to send the paperwork directly to them.

5. Final notice (30+ days late)

Subject: Final notice: invoice #1042. Body: Hi Sam, invoice #1042 for $2,400 is now 30 days overdue. Please arrange payment by 17 November. If payment is not received or a payment plan agreed by then, we will need to move this balance to our formal recovery process. I would much rather resolve it with you directly.

Timing and cadence

A practical cadence is: three days before due, on the due date, then roughly 3, 14 and 30 days after. Each message should escalate a step. Sending the same email six times teaches the recipient to ignore you.

Keep a record

Log what you sent and when. If the balance ever becomes a dispute, that record is your evidence. AI Money Recovery drafts reminders from your own invoice data, requires your approval before anything is sent, and keeps every action in an audit trail.

Frequently asked questions

How do you politely remind someone to pay an invoice?

State the invoice number, amount and due date, attach the invoice, and ask a specific question such as whether it has been approved. Assume an administrative delay rather than bad intent.

How many payment reminders should I send?

Usually three to five, each escalating: a pre-due reminder, a due-date reminder, one or two overdue reminders, and a final notice.

When should I send the first payment reminder?

A few days before the due date is ideal. It catches approval problems while there is still time to fix them.
