Communicate Effectively with Professional Payment Reminders

A payment reminder is often the final prompt that encourages customers to settle outstanding invoices. But how do you draft one correctly? And how do you ensure it is professional and legally compliant? In this article, we show you how to write a payment reminder—with a sample text, a template, and how KLEVERBILL supports you throughout the process.

Why a Professional Payment Reminder Matters

A payment reminder is not only a notice of overdue payment, but also part of your customer communication. It should be clear and legally accurate without unnecessarily alienating the customer. Professional payment reminders demonstrate that you take your claims seriously—and can help secure your liquidity.

Benefits of a well-written payment reminder:

• Signals professionalism

• Supports the customer relationship

• Provides legally reliable documentation for any follow-up steps

How to Write a Payment Reminder

A payment reminder should include the following elements:

• Customer name and address

• Reference to the outstanding invoice (invoice number, date, amount)

• Reference to the original due date

• A clearly defined payment deadline

• Friendly but firm tone

Sample text for a first payment reminder:

Subject: Payment reminder for your invoice no. 12345 dated 15/05/2025

Dear Ms./Mr. Sample,We would like to remind you that the above-mentioned invoice in the amount of EUR 1,200.00 was due on 15/06/2025.
