How do I add a late payment fee to a freelance contract?

Add a late fee to your freelance contract: monthly percentage, start date and the right to pause work. Clear wording plus a polite email.

The risky clause

No late fee or interest shall apply to delayed payments.

Why it is dangerous

Without a late fee, delay costs the client nothing. A modest monthly fee and a right to pause work encourage on-time payment. Check any legal cap on interest in your jurisdiction. This is general information, not legal advice.

Safer clause to propose

Invoices unpaid after the due date accrue a late fee of 1.5% per month, or the maximum permitted by law if lower. The Contractor may pause work while any invoice is overdue.

Message to send

Hi [Client],

Could we add a late fee of 1.5% per month on overdue invoices and the right to pause work while one is overdue? It is a standard term. Thanks, [Your Name]

Frequently asked questions
