Friendly Reminder Invoice Email (Before or On the Due Date)

The cheapest reminder is the one sent before the invoice is late. A friendly heads up two or three days before the due date catches most "forgot to approve it" delays while there is still time to fix them.

When to send it

Two to three days before the due date, or on the due date itself. Skip it for clients who always pay on time.

Friendly reminder: invoice [INVOICE #] due [DUE DATE]
Hi [CLIENT NAME],

A friendly heads up that invoice [INVOICE #] for [AMOUNT] is due on [DUE DATE].

In case it's handy:
Pay to: [BANK DETAILS / PAYMENT LINK]
Reference: [INVOICE #]

Let me know if you need anything from me to get it approved.

Thanks,
[YOUR NAME]

Variant: On the due date

Invoice [INVOICE #] is due today
Hi [CLIENT NAME],

Just a note that invoice [INVOICE #] ([AMOUNT]) is due today. Payment link: [LINK].

Thanks, and have a good week!

Mistakes to avoid

  • Calling it a "friendly reminder" when it's already 30 days late. Match the label to the stage.
  • Sending it to clients with automatic payment, which looks disorganised.
  • Leaving out the payment link.
  • Adding a late fee warning in a pre-due-date message.

FAQ

How do you write a friendly invoice reminder?

Keep it to three or four lines: invoice number, amount, due date, payment link, and an offer to help with approval.

Is it OK to remind a client before the due date?

Yes. A short heads up a few days before is common and helps the invoice get into the payment run.

Invoice INV-0042: payment reminder
Send
Hi Northwind Studio,

Invoice INV-0042 for USD 2,400.00 was due on October 20, 2026. I don't have the payment on my side yet.

Probably an oversight, so here are the details again:

Amount: USD 2,400.00
Reference: INV-0042
Pay to: details on the invoice (attached again)

If it has already gone out, send me the transfer date and I'll match it on my end.

Thanks,
Alex Rivera

Still not paid after Day 30?

That is when another email stops working. The Late-Payment Rescue Pack has what I send when a client goes quiet:

  • A formal final notice letter in Word, ready to sign and send as a PDF.
  • Emails for charging a late fee and agreeing a payment plan, in English and Spanish.
  • Late payment clauses and a freelance contract so it does not happen again.
