Polite payment reminder messages: 15 templates from friendly to final notice
How to remind a client to pay — before the due date, on the day and when it is late — with 15 polite payment reminder templates for email and WhatsApp.
A polite payment reminder states the invoice number, the amount and the due date in the first sentence, makes paying easy with a link or bank details, and assumes good faith — most late payments are forgotten, not refused. Send a friendly reminder a few days before the due date, another on the day, then firmer reminders at one, two and four weeks late. Keep every message short and factual.
A simple reminder schedule
- 3–5 days before the due date: a friendly heads-up.
- On the due date: a short reminder with the payment link.
- 7 days late: a polite follow-up asking if anything is holding it up.
- 14 days late: firmer, with a specific date to pay by.
- 30 days late: a final notice explaining what happens next.
Put the payment terms in writing before the work starts — the due date, how to pay, and any late fee. A reminder is far easier to send when it only points back to what was already agreed.

Tips that get invoices paid faster
- Always include the invoice number, amount and due date. The accounts team needs all three to find it.
- Attach the invoice every time. Do not make them search for the first email.
- Make paying one click, with a link or full bank details in the message.
- Use the channel they reply on. For small businesses and individuals, that is often WhatsApp rather than email.
- Thank them when it arrives. It closes the loop and keeps the relationship warm.
Late fees and interest depend on your contract and the law where you work, so check before you charge either.
Sending reminders without dreading them
Chasing money is the email everyone puts off. In Gmail, AI Reply Writer can write it from a short instruction — "chase the invoice politely" — or reply in the existing thread, where it reads the attached invoice so the reminder quotes the right number and amount. It works in Outlook and on WhatsApp Web too. You check the draft and send it yourself. The free plan includes 20 replies a month.
For other emails that went unanswered, see follow-up emails after no response.
