What to Do When a Customer Refuses to Pay: A Contractor's Guide

You finished the job. The customer won't pay. Here's a step-by-step guide to your options — from demand letters to mechanics liens to small claims court — and how to protect yourself at each stage.

Non-payment is every contractor's nightmare. You've put in the work, the materials, and the time — and now the customer has gone quiet or is disputing the invoice. Before you panic, know this: you have legal tools available to you. Here's how to use them.

Step 1: Send a Formal Written Demand

Before anything else, send a formal payment demand in writing — email is fine, certified mail is better. State the amount owed, reference the contract and completed scope, and give a clear deadline (typically 10–14 days). Keep the tone professional. This letter does two things: it gives a good-faith customer one more chance to resolve the issue, and it creates a paper trail you'll need if this goes further.

Step 2: Review Your Contract and Documentation

Pull out the signed contract and go through it carefully. What were the exact payment terms? Was there a defined process for disputes? Do you have signed change orders for any work beyond the original scope? Gather every piece of documentation: invoices, emails, photos of completed work, text messages, inspection sign-offs. This is your case file.

Step 3: File a Mechanics Lien

If payment doesn't arrive after the demand, your next move is typically a mechanics lien. This is a legal claim against the property for the value of the work you performed on it. A filed lien appears on the property's title and must be resolved before the property can be sold or refinanced. It's a powerful lever — especially on residential properties. Know your state's deadlines. In most states, you have a limited window (often 30 to 90 days from project completion) to file. Don't wait until you've been chasing payment for six months to start that clock.

Step 4: Consider Small Claims Court

For amounts under your state's small claims limit (typically $5,000 to $25,000 depending on the state), small claims court is often the fastest and cheapest legal option. You don't need a lawyer. You need your documentation and a clear presentation of what was owed and what wasn't paid. Winning a judgment doesn't guarantee payment, but it gives you collection tools — including wage garnishment and bank levies in many states.

Step 5: Consult a Construction Attorney

For larger amounts or complex disputes, a construction attorney is worth consulting. Many offer free or low-cost initial consultations. They can advise on lien enforcement, demand letters with legal weight, and whether a full lawsuit makes financial sense given the amount at issue. Don't assume legal action is too expensive without getting actual numbers.

After the Dispute: Leave a Review

Once the dispute is resolved — however it ends — leave a review on the customer's address on JobSite Recon. Be factual. Describe what happened with payment, what steps you had to take, and what outcome you reached. This review could save another contractor from the same experience.
