How to Write a Late Payment Clause (With Sample Text)

Most freelance invoices say something like "payment due within 30 days." Then day 31 arrives, the invoice is unpaid, and the contract says nothing about what happens next. You're left with polite reminder emails and no leverage.

A late payment clause fixes that by deciding, in advance, what happens when a payment is late — while the relationship is still friendly and nobody feels accused. Most clients never trigger it. Its main job is to make paying on time the obvious choice.

1. A clear due date — "within 14 days of the invoice date," not "promptly."
2. A grace period — a few days before anything kicks in, to cover genuine admin delays.
3. A late fee or interest — a flat fee, a monthly percentage, or both.
4. A work pause — your right to stop work until overdue invoices are paid.
5. Collection costs — who pays if you have to use a collection service or go to small claims.

Common approaches:

• Monthly interest on the overdue amount, often 1-1.5% per month.
• A flat late fee, for example a fixed amount once the grace period ends.
• Statutory interest, where your country provides it. In the UK, the Late Payment of Commercial Debts (Interest) Act lets businesses claim interest at 8% above the Bank of England base rate on business-to-business debts, plus fixed compensation. EU countries have similar rules under the Late Payment Directive.

Whatever you pick, keep it reasonable. Some jurisdictions cap interest rates or treat excessive fees as unenforceable penalties — so a modest, clearly stated fee is both fairer and more likely to hold up.

Adapt the numbers to your situation:

Sample clause:
"Invoices are due within 14 days of the invoice date. If payment is not received within 7 days after the due date, the following applies: (a) interest accrues on the overdue amount at 1.5% per month, or the maximum rate permitted by law if lower; (b) the Freelancer may pause all work until overdue amounts are paid in full, and any agreed deadlines are extended by the length of the pause; (c) the Client is responsible for reasonable costs of collecting overdue amounts. Ownership of deliverables transfers to the Client only after full payment."

Each part pulls its weight. The work pause stops you from stacking up more unpaid hours. The deadline extension means a client can't pay late and then complain you missed a date. And linking ownership to payment gives you real leverage without any threats.

A clause only helps if you use it consistently. A simple sequence:

1. Due date: a friendly reminder with the invoice attached.
2. Grace period ends: a short note that the invoice is now overdue and late terms apply from today, quoting the clause.
3. 14 days overdue: pause work and say so, in writing.
4. 30+ days overdue: a final notice with the total including interest, and the date after which you'll use a collection service or small claims.

You don't always have to charge the fee — waiving it for a good client who was a few days late is a nice gesture. But you can only waive a fee you had the right to charge in the first place.

The strongest protection against late payment is getting paid before most of the work is done. A deposit at signing, plus milestone payments, means the amount at risk at any moment is small. See how much deposit freelancers should charge for typical ranges.

This article is general information, not legal advice. Interest limits and late-payment laws differ between countries and states, so check what applies before setting your rate.

Every one of our free contract templates — starting with the general freelance service agreement — includes payment terms you can adapt with the clause above. With Clinch, the client signs from their phone with no account and pays the deposit at signature, so a big part of the fee is already in your account before the first invoice could ever be late.
