Friendly Payment Reminder Letter Template

Most late invoices are simple oversights, so the first reminder should be short and friendly. It still does real work: it puts the balance in front of the right person and starts a written record that you asked.

RE: Invoice #[Number], [$Amount]

Dear [Client Name],

A quick reminder that invoice #[Number] for [$Amount] was due on [Due Date] and is still open on our books.

If payment is already on the way, thank you. If not, you can pay by [Payment Method / Link]. A copy of the invoice is attached.

If anything on the invoice looks wrong, let me know and I'll sort it out.

Thank you,

[Your Name]

When to use this letter

  • The invoice is 1 to 30 days past due and this is your first written follow-up.
  • The client usually pays on time, so an oversight is the likely explanation.
  • You want a paper trail started without changing the tone of the relationship.

Tips

  • Send it sooner than feels comfortable. The older an invoice gets, the harder it is to collect.
  • Attach the invoice so paying takes no extra effort on their side.
  • Give one clear way to pay. Every extra step slows the payment down.
