Payment Reminder Templates for Overdue Invoices (Copy and Use)

By Kurt Francisco Pavia, founder of 11:11 Websites · Updated October 23, 2026

Most late invoices are forgotten, not refused. A friendly, consistent reminder schedule gets you paid without awkward calls.

A reminder schedule that works

Template 1: Before the due date

Hi {Name}, a quick heads-up that invoice #{number} for {job} ({amount}) is due on {date}. You can pay here: {link}. Thanks again for choosing us. — {Your name}

Template 2: Due today

Hi {Name}, just a reminder that invoice #{number} ({amount}) is due today. Here's the payment link: {link}. Let me know if you have any questions.

Template 3: 7 days overdue

Hi {Name}, invoice #{number} for {amount} is now 7 days past due. Could you take care of it this week? Payment link: {link}. If something's wrong with the invoice, reply and I'll sort it out.

Template 4: Final reminder

Hi {Name}, invoice #{number} ({amount}) is now 14 days overdue. Please pay by {date} using {link}. If we can't resolve it by then, {next step from your terms}.

Tips

Automating reminders

An AI agent can send these on schedule, stop as soon as payment arrives and flag anyone who needs a personal call from you. You approve the templates once.

Prevent late payments before they happen

Text message versions

Many customers respond faster to a text, as long as they've agreed to receive texts from you:

Hi {Name}, it's {Your name} from {Business}. Friendly reminder that invoice #{number} for {amount} is due {date}. Pay here: {link}. Thanks!

When to stop sending reminders

If a customer disputes the invoice, stop the automatic reminders and talk to them personally. If they don't respond after your final reminder, follow the next step in your written terms and consider getting advice on collections.

Questions

Is it rude to send payment reminders?

No. Clear, polite reminders are normal business practice and most customers appreciate them.

Should I charge late fees?

Only if your written terms say so and they comply with your state's rules. State them on every quote and invoice.
