A client won't pay my invoice

You completed the work you agreed to, sent the invoice, and then the client stopped responding, disputed the amount, or simply refused to pay. It feels like a betrayal of trust and a waste of your time and effort. There is a real, ordered set of options you can follow to try to resolve this, from direct communication to formal legal steps.

The honest reality

Not every unpaid invoice gives you a legal claim. What separates a real case from a bad experience is whether you have a clear agreement, written or otherwise, that shows exactly what work was promised, what was delivered, and that the client agreed to pay for it. If the client genuinely disputes the quality or scope, you may have a disagreement rather than a clear breach, and that changes your options.

Your real options, cheapest first

  1. 1. There is no regulator here. This is a private contract dispute, not something a regulator polices, though if you did licensed trade work, a lien may be available even before you sue.
  2. 2. A demand letter. A written demand with the invoice, the scope of work, and a firm deadline is the standard, professional first step, and courts expect to see that you tried.
  3. 3. Small claims court. Unpaid invoice disputes are one of the most common and best-suited small claims cases; bring the contract or written agreement, the invoice, and any messages confirming the work was accepted. No lawyer required; see our pro se guide.
  4. 4. A lawsuit. For licensed trade work, some states let you file a lien against the property before or instead of suing; for larger amounts beyond small claims limits, a contract or collections lawyer is the next step.

You don't need a lawyer to start

You are allowed to do this yourself

A regulator complaint, a demand letter, and small claims court are all built for people without lawyers.

Questions

Can I sue the client for not paying my invoice?

You can, but suing is usually a last resort. Before you consider that, you need to confirm you have proof of the agreement, the work you did, and the client's refusal to pay. Small claims court is an option for smaller amounts, but the rules and limits vary by state, and you should weigh the cost and time against what you are owed.

What if the client says the work was not good enough?

Then the dispute is about quality, not just non-payment. You need to review the original agreement for any specific standards or acceptance criteria. You may need to show that you met those terms, or consider whether a partial payment or rework is a practical solution before escalating.

How do I start the process to get paid without a lawyer?

Begin with a clear, written demand, send a final invoice and a letter or email stating the amount due, the work completed, and a deadline for payment. If that fails, you can send a formal demand letter or use a mediation service. The exact next steps depend on your state's laws and the amount involved, but you can often find free resources through your local small claims court or a business association.
