1. Sending an invoice

New invoice email

Use when you first send the invoice. Sets the due date expectation clearly.

Subject: Invoice [#1042] from [Your Business] — due [Due Date]

Hi [Client Name],

Thanks again for working with us on [project/service]. Please find invoice [#1042] for [$amount] attached.

Payment is due by [Due Date]. You can pay by [payment methods — bank transfer, card link, etc.].

If anything on the invoice looks off, just reply and I'll sort it out right away.

2. Friendly reminder (a few days before or just after due date)

Polite payment reminder

Use around the due date. Assumes good faith — most late payments are just forgotten.

Subject: Quick reminder — invoice [#1042] due [Due Date]

Hi [Client Name],

Just a quick note that invoice [#1042] for [$amount] is due on [Due Date]. I've attached a copy in case the original slipped through.

If it's already been paid, thank you — no action needed.

3. Overdue follow-up (1–2 weeks late)

Firm but professional follow-up

Use when the invoice is clearly overdue. Asks for a specific commitment.

Subject: Overdue: invoice [#1042] — [X] days past due

Hi [Client Name],

Invoice [#1042] for [$amount] was due on [Due Date] and is now [X] days overdue. I haven't received payment or heard from you about it.

Could you let me know today when I can expect payment? If there's an issue with the invoice or cash flow timing, I'm happy to talk it through — I just need a firm date.

A copy of the invoice is attached.

4. Final notice (30+ days late)

Final notice before further action

Use as the last email before late fees, pausing work, or collections. Calm, factual, specific.

Subject: Final notice — invoice [#1042], [X] days overdue

Hi [Client Name],

Despite previous reminders, invoice [#1042] for [$amount] (due [Due Date]) remains unpaid — now [X] days overdue.

Please arrange payment within 7 days, by [Final Date]. If payment isn't received by then, I'll have to [add late payment interest at X% / pause current work / refer the balance to collections], which I'd much rather avoid.

If payment has been sent in the last few days, please send the reference so I can trace it.

FAQ

How soon should I follow up on an unpaid invoice?

Send a friendly reminder on or just after the due date, a firm follow-up at 7–14 days overdue, and a final notice at 30 days. Consistent, predictable escalation gets invoices paid faster than one angry email at day 60.

Should I mention late fees?

Yes — if your contract or invoice terms allow it. Even mentioning that interest is accruing (see the late fee calculator) often prompts payment, and you can waive the fee once paid.

What if the client disputes the invoice?

Split the disputed part from the undisputed part and ask for immediate payment of the undisputed balance while you resolve the rest. This keeps cash moving and shows good faith.
