How to get paid when a client won’t pay your invoice

Late payments are a fact of freelance life. A clear escalation, from reminder to formal demand letter, gets most clients to pay without going to court.

1. Check your contract and invoice

Confirm the due date, payment terms, any late fee, and that the invoice went to the right person with the right details.

2. Send a friendly reminder

Many late payments are oversights. Resend the invoice and ask when you can expect payment.

3. Send a formal demand for payment

If reminders are ignored, send a demand letter stating the amount owed, the invoice number, the original due date, any contractual late fee, and a firm deadline. Mention what you will do next if it is not paid.

4. Pause further work

Consider stopping new work until the balance is paid, if your contract allows it.

5. Escalate if needed

Small claims court is designed for people without lawyers, and limits vary by state. Your state consumer protection office can point you to resources (find yours at USA.gov). For large amounts, a collections agency or attorney may help.

What your letter should include

• Your name and business details
• The invoice number, amount, and original due date
• A summary of the work completed
• Any late fee allowed by your contract
• A clear payment deadline and how to pay
• What you will do if it is not paid

Keep a copy of everything you send, and note the date you sent it.

Frequently asked questions

Can I charge a late fee?

Generally if your contract or invoice terms set one in advance. Adding a new fee later is harder to enforce.

How long should I wait before sending a demand letter?

Many freelancers send a reminder right after the due date and a formal demand after 15 to 30 days of silence.

Do I need a lawyer for small claims court?

Usually not. Small claims courts are built for people representing themselves; check your state’s limits and rules.
