How to write a payment reminder letter

Open with the reference

Put the invoice number, the amount and the due date in the first lines, under a "Re:" line. The person opening it should know what it is about before they read the first sentence.

Be formal, not cold

Formal means clear, not unfriendly. State the facts, ask for payment and offer to talk. If you would be comfortable reading it aloud to the customer, the tone is right.

Date it and keep a copy

A dated copy is your record of when you asked. If a reminder is ever followed by something more serious, the dates are what matter.

Send it a way you can show

Email the letter as a PDF, or post it and keep the receipt. What matters is that you can show it reached them.

Questions about payment reminders

When should I send a payment reminder letter?

After an email or two has gone unanswered, or when the customer expects something formal, such as a business or a property manager. It usually sits between a friendly reminder and a final notice.

What should a payment reminder letter include?

The date, who it is to, the invoice number, the amount, the due date, how to pay and how to reach you. The letter this tool writes is built from those.

Is a reminder letter the same as a demand letter?

No. A reminder asks politely for something already agreed. A demand letter is a firmer, often legal, step with deadlines and consequences. This tool writes reminders and never threatens action. For a large amount, ask a lawyer about your options.

Can I use the letter in Word or Google Docs?

Yes. Copy it, paste it into either, and add your letterhead and address. What you type here is not saved.
