A late invoice rarely needs a fight. It usually needs a calm reminder at the right time, and then a firmer one if nothing happens. A fixed schedule means you decide once, and then follow it every time.
1The five steps
| Step | When | Tone | What to say |
|---|---|---|---|
| 1 | 3 days before it is due | Friendly | A heads-up that it is coming, with the amount and how to pay |
| 2 | On the due date | Plain | It is due today, with the link or details to pay |
| 3 | 7 days late | Firm | It is now a week late, please pay today, reply if something is wrong |
| 4 | 14 days late | Firm | Second notice, with the new total if you have a written late fee |
| 5 | 30 days late | Final notice | Pay now, or reply to agree a plan |
Send them on working days, in the morning, so they are read.
2Example wording
**Step 2:** "Hi Sarah, invoice INV-0039 for $2,598.00 is due today. You can pay by Zelle to [email protected]. If you already paid, thank you, and tell me so I can check."
**Step 3:** "Hi Sarah, $2,598.00 is still unpaid. It was due on Oct 30 2026. Please pay it today. If something is wrong, reply and I will help."
Keep each message short, with the invoice number, the amount, the due date and one way to pay.
3Stop when it is paid
Stop the schedule when the money arrives, when your client says they paid and you are checking, or when you have agreed a new date in writing. Never send a reminder for something that is paid. Check your own account before you confirm a payment.
4What if they still do not pay?
After the final notice, think about the next step: a call, a written payment plan, or advice from someone who knows the rules where you work. Collection rules and late fees differ by place, so ask before you add fees or send anything formal.

Questions people ask
Should I charge a late fee?
Only if you said so before the job and on every invoice. See how to set late fees.
How many reminders is too many?
Five, spread over a month, is a reasonable chase. More than that, speak to the client directly.
Can reminders go out on their own?
In the InvoiceWren app they can: it emails your client from your name on these days, and stops when it is paid. You can turn it off for any invoice.
