What to do when a client won't pay
When a client won't pay, work the problem in order: confirm they received a correct invoice, get a firm reason in writing, escalate to a phone call and a dated final notice, then send a certified demand letter. If that fails, small-claims court or a collections partner is the last resort. Most disputes resolve well before that.
First, find out why
"Won't pay" is usually one of four things, and each has a different fix:
- Can't find or approve it: the invoice is lost, missing a PO number, or stuck with a manager. Resend a clean copy and ask who approves it.
- Cash-flow timing: they intend to pay but are short. Offer a payment plan with dated instalments.
- A dispute: they are unhappy with the work or the amount. Get the specific objection in writing and resolve it.
- Avoidance: they are simply dodging. This is where firm, documented escalation matters.
Escalate in the right order
Do not jump straight to threats. Move through the ladder, keeping everything in writing: a firm reminder, a phone call, a dated final notice, and then a certified demand letter. Each step should reference the last, so the trail shows a reasonable business that gave every chance to pay.

Protect yourself while you chase
Two protective moves matter. First, pause new work for that client until the current invoice is current, and say so plainly. Second, keep your evidence together: the signed quote or contract, proof of delivery or sign-off, and the full reminder history. That evidence is what makes a demand letter credible and a small-claims case winnable.
The last resort: demand letter, then court
If the ladder fails, a certified demand letter is the strongest low-cost step. If that is ignored, small-claims court is designed for exactly these amounts and usually does not require a lawyer. Collections agencies are an option too, though they typically take a significant percentage of what they recover.
Frequently asked questions
What can I do if a client refuses to pay an invoice?
Diagnose the reason first, then escalate in order: a firm written reminder, a phone call, a dated final notice, and a certified demand letter. Pause new work until they are current, and keep your contract and proof of delivery together. If all that fails, small-claims court is built for these amounts.
When should I take a client to small-claims court over an unpaid invoice?
Consider small-claims court after a certified demand letter has been ignored and the amount is within your local small-claims limit. It is designed for these disputes, usually needs no lawyer, and your documented reminder history and contract make it winnable. Most clients settle once they see you are prepared to file.
Should I stop working for a client who has not paid?
Yes. Pausing new work until the outstanding invoice is settled is one of the most effective and legitimate levers you have, especially for ongoing or retainer relationships. Say it plainly and without hostility: work resumes when the account is current. It protects your cash flow and signals that terms are real.
Can I charge interest on an invoice a client refuses to pay?
If your contract or invoice terms stated a late fee or interest rate before the work, you can usually apply it, commonly 1 to 1.5 percent per month. State it up front, include it in your demand, and check local caps on interest. Do not invent a fee after the fact, as that weakens your position.
