What to do when a client won't pay

This guide is for the point where prevention has already failed: an invoice is overdue, the reminders have gone out, and the client has stopped responding or has told you outright they are not paying. If you want to stop this happening in the first place, see how to get paid on time, which covers deposits, terms, and a reminder ladder. Here, the question is narrower: the money is already unpaid, so what do you actually do next.

Confirm the facts before you escalate

Before you send anything formal, check the parts of the situation that are easy to get wrong under stress. Confirm the invoice went to the right person and the right email address, not just the general inbox you always use. Confirm the due date and the amount match what the contract and any signed proposal actually say. Check whether the client has raised any complaint about the work itself; if they have, you are dealing with a dispute, not a simple refusal, and the next section covers that separately. If none of that turns anything up, and the silence or refusal is real, move to a formal written demand.

Tell a slow payer from a refusing payer

These need different handling. A slow payer is still engaging: they answer messages, cite a real reason (an internal approval delay, a cash-flow gap, an accounts-payable cycle), and give you some sense of a date. Keep working the reminder ladder from the getting-paid guide with this group; a firmer tone and a real deadline usually gets there. A refusing payer stops responding entirely, disputes the invoice for the first time only after it is sent, or tells you directly they will not pay. That is who the rest of this guide is for.

Send a formal demand letter

One written notice, sent by email and, for larger amounts, also by any postal address you have, that lays out the facts plainly and gives one real deadline. It should include:

• The invoice number, date, and amount owed. State the currency and the exact figure, not a rounded one.
• The due date and how many days overdue it is. Specific numbers read as someone who is tracking this closely, which they should be.
• The contract clause that entitles you to payment, quoted or referenced directly, so there is no room to claim the terms were never agreed.
• Any interest accruing. If your contract has a late-payment clause, state the rate and the amount already accrued. The late payment calculator works this out from the due date and the rate so you can quote a real figure instead of a threat.
• One firm final deadline. Seven to fourteen days is standard. Pick a real calendar date, not "soon."
• What happens if the deadline passes. State it plainly: continued interest, referral to collections, or a small claims filing. Only say what you are actually prepared to do.

Keep the tone factual and free of anger. A letter that reads like an accounting statement is harder to dismiss than one that reads like a complaint, and it is also the version you would be comfortable showing to a court or a collections agency later.

If they dispute the work

Handle a quality or scope complaint as its own question, separate from the fact that money is owed. Ask the client to state in writing exactly what falls short of what was agreed, and compare that against your contract, the signed scope, and any approvals collected along the way. A complaint that matches something you can point to in the paperwork deserves a real look; a partial payment or a bounded, agreed fix often resolves it faster and cheaper than a fight. A complaint that surfaces for the first time only after the invoice lands, and was never mentioned during delivery or at an earlier review, is a pattern worth noting when you decide how far to compromise.

If the project is ending because of the dispute rather than continuing, work out what is actually owed for the work already done before you argue over the rest. The kill fee and deposit calculator splits a stopped project into the value of work completed, any kill fee on the remaining balance, and what a deposit already covers, so the number you are asking for is defensible rather than a guess.

Decide whether it's worth pursuing

Chasing a debt costs time, and your time has a price. Before you escalate further, weigh:

• The amount owed against the filing fee and hours required. A few hundred dollars rarely justifies days of your time; a few thousand usually does.
• Whether the client can actually pay. A judgment against a client with no money or assets, sometimes called being judgment-proof, is a piece of paper, not cash. This matters more for a struggling small business or an individual than for an established company.
• How much proof you have. A signed contract, a clear invoice trail, and delivered work with evidence of acceptance make any of the paths below far more likely to succeed.

Escalation paths: small claims, collections, or a lawyer

Small claims court is built to run without a lawyer, with a filing fee that is usually small next to a mid-sized invoice and a process designed for exactly this kind of dispute. The claim limit, process, and typical timeline vary by country and by state or province, so check your local court's website before filing. It suits cases where you have clear paperwork and the amount justifies a few hours of your time and a modest fee.

A collections agency typically works on commission, keeping 25 to 50 percent of whatever it recovers, so it costs nothing if it recovers nothing. That makes it a reasonable option for larger invoices once direct contact has failed and you would rather hand off the chasing than spend more of your own time on it.

A lawyer's letter, even a single one, carries weight that an email from you does not always carry, and can be inexpensive relative to what is owed. Some lawyers will also advise, for a flat fee, on whether a specific claim is worth pursuing before you spend more time on it.

Writing off the debt

Sometimes the right call is to stop. If the amount is small, the client is unreachable or has no realistic way to pay, and further hours spent chasing cost more than they could recover, write it off and move on. Whether an unpaid invoice can be treated as a deductible bad debt depends on your accounting method and your country's tax rules; a freelancer on cash-basis accounting who never recorded the invoice as income typically has nothing to deduct, since the loss was never taxed as a gain. Check this with a tax professional rather than guessing, and see freelancer tax basics for the general picture of how freelance income is taxed.

Take the lesson forward rather than only the loss. Almost every non-paying client was visible as a risk earlier than the freelancer wanted to admit: no deposit, vague terms, or a contract with no late-payment or pause-work clause. The contract clause library has ready-to-use wording for payment terms, deposits, and late interest, and how to get paid on time covers the screening signals that flag a risky client before you ever start the work.
