Late payment is mostly a follow-up problem. Most clients are not refusing to pay; they forgot, or the invoice is stuck with someone else. A short, polite and predictable reminder sequence fixes most of it, and you can automate it.
This guide gives a schedule and templates, then shows which invoicing tools send reminders for you. Tool details come from vendors' published pages, checked October 20, 2026. We did not test each reminder system.
A reminder schedule that works
| When | Message | Tone |
|---|---|---|
| 3 days before due | Heads-up that the invoice is due | Friendly |
| Due date | Invoice is due today, with payment link | Neutral |
| 3 days late | Quick check that it arrived | Polite |
| 7 days late | Ask if there is a problem, restate terms | Firm |
| 14 days late | Mention late fees, ask for a date | Firm and clear |
Adjust for your own terms. If you do not charge late fees, do not mention them.
Templates
Before the due date. "Hi [Name], a quick note that invoice [number] for [amount] is due on [date]. You can pay here: [link]. Thanks!"
7 days late. "Hi [Name], invoice [number] was due on [date] and I have not seen payment yet. Could you let me know when to expect it, or if anything is holding it up?"
14 days late. "Hi [Name], invoice [number] is now 14 days overdue. As per our agreement, [late fee terms]. Please confirm a payment date by [date]."
Which tools send reminders for you
Built-in reminders by tool
Several tools automate reminders, but plans differ.
- FreshBooks

For details on each tool, see our invoicing software comparison.
Optional: add your own automation
If your invoicing tool lacks reminders, an automation tool like Zapier or Make can send an email when an invoice passes its due date. Each reminder uses at least one task or credit, so a daily schedule can use units quickly. Count them first with how Zapier and Make count usage.
Habits that help more than reminders
- Put the due date and payment link at the top of the invoice.
- Invoice on the day the work is done.
- Ask for a deposit on larger projects.
- Know who approves invoices at the client and send it to them directly.
- Write your late-fee terms into the contract before you need them. Check local rules on what you can charge.

Frequently asked questions
Will reminders annoy clients?
Polite, predictable reminders are normal business practice. A schedule keeps them from feeling personal.
Should I charge late fees?
Only if your contract says so, and check the rules where you work.
