Payment reminder email

A payment reminder email for a late invoice. Pick a tone, say how many days overdue it is, copy the email. The wording changes with the lateness, so a first nudge doesn't read like a final demand.

Tone

Assumes it slipped through. Good for the first nudge.

Subject: Quick reminder: invoice [invoice number]
Hi there,

I'm writing about invoice [invoice number] for [amount], which was due on [due date]. I haven't seen the payment come in yet, so I wanted to check it reached the right person.

If it's already been paid, thank you, and could you send me the payment date so I can match it? If anything on the invoice needs changing, tell me and I'll sort it out.

Thanks,
[Your name]

Questions

When should I send the first payment reminder?

A day or two after the due date. Early on, most late payments are an invoice sitting in the wrong inbox, so the first email should assume that and make it easy to pay.

How many reminders should I send?

Usually three: a friendly one just after the due date, a firm one about two weeks later asking for a payment date, and a final notice with a deadline once it is a month or more overdue. Pick up the phone somewhere in between if the amount matters.

Can I charge a late fee?

If your contract or terms say so, and in some countries the law allows interest on late business payments even without it. Only mention a fee in the reminder if you're entitled to it and prepared to charge it.

Is this written by AI?

No. They are fixed templates. The same choices always produce the same email, and nothing you type is sent anywhere.
