Put a clear due date on every invoice, check unpaid invoices once a week, and send the same three reminders on a fixed schedule: on the due date, seven days later and fourteen days later. Clients pay faster when follow-ups are predictable, not when they are angry.
Before you send the invoice
Most late payments start with an unclear invoice. Three details prevent a lot of chasing:
- A real due date. Write "due 15 October", not "on receipt" or "net 30".
- Payment details that work: bank details or a payment link, with the invoice number as the reference.
- The right person. Ask who approves invoices and send it to them, not only to your day-to-day contact.
Agree on payment terms before you start the work, and put them in writing. A short line in your proposal is enough.

A weekly check that takes ten minutes
Pick one day, Monday works well, and look at every invoice that is sent but not paid, sorted by due date. Anything past its due date gets the next reminder in the sequence. That is the whole system. It only works if you can see all unpaid invoices in one place, so keep one list instead of searching your inbox.
The three reminders
Copy these, change the names and numbers, and send them on schedule. They are short on purpose.
1. On the due date: a friendly nudge
Hi Sam, a quick reminder that invoice INV-012 for 1,200 is due today. The payment details are on the invoice, and I've attached it again here. Thanks!
2. Seven days late: ask for a date
Hi Sam, invoice INV-012 for 1,200 was due on 15 October and I haven't seen the payment yet. Could you let me know when it's scheduled? Happy to resend anything you need.
3. Fourteen days late: a direct conversation
Hi Sam, invoice INV-012 is now 14 days overdue. Could we have a quick call this week to sort it out? Per our agreement, I'll pause new work on the project until it's settled.
Only mention pausing work if your agreement allows it, and do what you say. After the third message, a phone call usually works better than another email.
Habits that keep payments on time
- Invoice on the day the work is delivered, not at the end of the month.
- For new clients or bigger projects, ask for a deposit before you start.
- Split long projects into milestones and invoice each one.
- Thank clients who pay on time. It is noticed.
- Keep a note of how long each client takes to pay. It helps when you price the next project.
Questions
Should I charge late fees?
Only if they are in your agreement and allowed where you work. Many freelancers keep them in the contract and rarely use them; the reminders do most of the work.
What if a client stops replying?
Call, then send a final written notice with the amount, the due date and a deadline. If that fails, check the options for small claims or a collection service in your country.
Is it rude to send reminders?
No. Reminders are a normal part of business, and accounts teams often rely on them. A polite, regular follow-up is more professional than silence followed by frustration.
