Payment reminder email

A payment reminder email is a short, friendly note that an invoice is due soon or just went past due. Include the invoice number, the amount, the due date and how to pay, and keep the tone warm. It's a nudge, not a complaint.

Send the first one a few days before the due date if the client is new or the invoice is large, then a second right after the due date passes. If that gets no reply, it has become an overdue invoice and needs a firmer email.

Polite reminder on the due date

Gentle reminder just after the due date

Subject: Checking in on invoice [invoice #]

Hi [Name], Hope all is well. I'm checking in on invoice [invoice #] for [amount], which was due on [due date]. Could you let me know when I can expect payment? [payment link] Thank you, [Your name]

How to customize it

  • Swap every [bracket] for your details and keep the invoice number in the subject line so it's easy to search.
  • Use the client's first name and your usual sign-off. A reminder should sound like you.
  • For a long-term client, add one line about the work, like how the launch went. It keeps the note warm.
  • Pick the version that fits the timing: before the due date, on the day, or just after.
  • Keep it under 80 words. Short reminders get read and paid faster.

Common mistakes

  • Apologizing for asking to be paid. You can be friendly without saying sorry.
  • Leaving out the amount or due date, which makes the client go hunting for the invoice.
  • Adding a jab like "on time this time". It turns a nudge into a complaint.
  • Sending a reminder to the wrong person. Ask who handles payments if you're not sure.
  • Writing a new message from scratch each month. Save a template and reuse it.

What to send next

If the due date passes with no payment and no reply, follow up with an overdue invoice email that asks for a specific payment date. If the client pays, a quick thank-you keeps the relationship in good shape.
