Late Payment Reminder Template

Use this late payment reminder template when an invoice is past due and you want to follow up without sounding aggressive. The best reminder is short, specific, and easy for the customer to act on. Include the invoice number, balance, due date, accepted payment method, and a simple request for an update.

A reminder should not create confusion or introduce new terms that were never shown on the original invoice. If you plan to mention a late fee, interest, or service hold, make sure the wording matches the agreement you already gave the customer and the rules that apply to your situation.

Before You Send The Reminder

Use the free Late Fee Calculator only if your original payment terms allow a fee or interest charge and the invoice still has a positive Balance Due. Otherwise, keep the first reminder focused on the overdue balance and payment instructions.

What To Include In A Late Payment Reminder

Customer name and invoice number.
Original due date and current balance due.
Payment method or payment instructions.
A polite request for confirmation or an update.
Any late fee wording only if it was already part of the agreed terms.

When To Send A Reminder

Many small businesses start with a friendly reminder a few days after the due date. If the balance remains unpaid, the next message can be more direct while still staying professional. Keep a copy of each reminder with the invoice record so you can see when follow-up was sent.

For future invoices, clear payment terms help reduce reminder work. Add a due date, accepted payment methods, deposit details if applicable, and any late-payment wording before the invoice is sent.

Before sending a reminder, check whether Amount Paid / Deposit Credited has changed. If an overpayment, return credit, or adjustment creates a Credit / Overpayment Balance, the message should be about the credit or refund status, not late payment.

FAQ

Should the first reminder mention a late fee?

Only mention a late fee if it matches the terms you already gave the customer and is allowed where you operate. Many first reminders simply restate the overdue balance.

How long should a late payment reminder be?

Keep it short. The customer should immediately see the invoice number, balance, due date, and payment instructions.

Can I use this template for legal collection notices?

No. This is a practical communication template, not legal advice or a formal collection notice.
