How to write off a bad debt
There is a point where chasing an unpaid invoice costs more than the invoice — in hours, in attention, in the work it pushes aside. Writing off a bad debt is not surrender, and it is not failure. Done deliberately, it is the moment a loss stops growing and starts teaching: the file closes, the number leaves your head, and what remains is a rule that makes the next loss less likely. This guide is about choosing that moment on purpose instead of drifting into it — the test that says stop, the close-out that makes it a decision, and the lesson to collect. It is general business information, not legal or tax advice; where a question turns on either, it says so and points to the right professional.
1. The stop test
Stopping is a decision, and decisions need criteria. These three questions, in this order, are the criteria — answered in writing, because an afternoon of honesty now is cheaper than a year of low-grade chasing.
Has the full ladder actually run? Not most of it — all of it. The reminders, the firmer notices, the final notice naming a date and a consequence, the formal routes priced and considered: the sequence our guide to what to do when a client won't pay lays out in order. A ladder abandoned at the third rung is not evidence that the debt is dead; it is evidence that the chasing was. If rungs remain, this guide's answer is to go back and finish them. The write-off is the end of that road, not a turning off it.
Is the client still there? A business that has dissolved, vanished or stopped trading is a different problem from one that is open, busy and choosing not to pay you. The first is close to uncollectable by anyone, and the hours spent chasing it are almost certainly wasted. The second may still respond to the formal routes — or to time. So establish which debtor you actually have before pricing anything: the company's public status, a phone number that is answered, a website that still trades.
What is the next hour of chasing worth? Price it the way every route on the ladder is priced: the amount, times your honest chance of recovering it, against your rate for the hours more chasing will take. Put real numbers on it. A $1,900 invoice with an honest 20% chance of ever being paid — honest, not hopeful — carries an expected value of $380. Six more hours of letters, forms and follow-up at a $95 rate is $570 of working life spent on it. The chase now costs $190 more than it can reasonably return. Turned around, the same arithmetic gives you the threshold: at six hours, chasing only pays if your honest chance is 30% or better. Below that line, every further hour is a second, smaller bad debt — volunteered. When the three answers line up — ladder finished, debtor gone or unmoved, numbers underwater — the test has answered. Stop.
2. The close-out
Drifting looks like stopping but isn't: the emails slow down, the invoice stays open in the ledger and in your head, and the client stays theoretically welcome. A close-out is three deliberate acts, done once, that make the decision real.
Send the final letter. Short, factual, unemotional: the invoice identified, the chase summarised in a line, the account closed, and your position reserved in general terms. No threats, no pleading, no new deadline you do not mean. It is a shape to adapt, not legal drafting — if the amount justifies it, a lawyer's version is a better buy than yours. The shape, at 88 words:
Dear [Name], I am writing to close the account for invoice [number], dated [date], for [amount], which remains unpaid after the reminders sent on [dates] and my final notice of [date]. I have recorded the balance as written off in my books and closed the file. This is an accounting decision, not a release of the debt, and I reserve any rights I may have in it. If you wish to settle, the full amount remains payable, and on receipt I will confirm closure in writing. [Your name]
Make the books entry. Mark the invoice written off in your records, with the date and a one-line reason — “ladder completed, debtor ceased trading” and the date is enough — and file it with the correspondence. That record is what an accountant works from when the year's numbers are prepared, and it is where the tax question belongs: how a written-off debt is treated depends on your tax system and on how the income was recognised in the first place, so it goes to your accountant as a question — the same discipline our guide to preparing for tax season applies across this whole territory. Your own systems should make the entry painless — one more dated line in the process document, which is the habit our guide to documenting your processes exists to build.
Decide the door, now. If this client reappears in a year, smiling, with a new project — what happens? Never again, on any terms? Or only with the old balance settled and the new work paid in full upfront? Either answer can be defended. What cannot is improvising the answer under flattery, with the loss forgotten. Write the decision into the client file, where your client list audit will surface it if the name ever enquires again. A door decision made in calm is a policy. One made in the moment is a relapse.
3. What writing it off is not
It is not forgiving the debt. A write-off is an entry in your books; it is not, by itself, a legal release of the debtor, and the two are routinely confused. Formal forgiveness — a release, a settlement, a discharge — is a legal act, and whether any of it has happened to your debt is a question for a lawyer, not for your ledger. Keep the distinction and you keep your options. Blur it in writing to the client, and you may have given away more than you ever meant to.
It is not a tax trick. You will hear that writing off a debt “saves tax”. Sometimes a written-off debt has a favourable treatment; often it has none at all, and which one you get depends on where you are and how the income was counted. Anyone promising you a benefit here without knowing your system is guessing, and a guess is not a reason to close a file. The write-off's real value is the stopped hours and the closed account. Ask the accountant the tax question separately, and treat any benefit that turns up as a bonus.
It is not public. No naming-and-shaming posts, no warnings about the client by name in public threads, no review left as revenge. It is the mirror image of the ethic in our guide to handling a bad review: private records, public silence. Beyond the exposure that public accusations can create, there is a simpler reason: the audience for your grievance is your next client, and they are watching how you behave when things go wrong.
And it is not a wall against being paid. Money occasionally arrives after a write-off — a new finance manager, a conscience, an old account finally settled. If it does: bank it, book it as the recovery it is, note it against the file. Then let the door decision stand anyway. A late payment settles a debt; it does not rewrite the history that priced the risk, and it buys no welcome back.
4. The lesson: the real repayment
The invoice is gone. What it can still pay you is information — but only if you collect it now, while the file is open on your desk. Every bad debt has a first chapter: the enquiry, the signing, the first small warning that got priced at zero. Re-read yours against the flags in our guide to spotting a problem client before you sign and find the one that was visible at the start. It is almost always there, and it is almost always specific: the deposit waived because they seemed keen. The milestone cut one slice too big. The approval that was verbal. The client who was already a third of the book.
Then choose one structural fix — the one that would have prevented this loss, picked from the evidence of this file rather than from a generic list. A larger deposit, or a harder ceiling on work running ahead of the money, sized with the deposit calculator. A milestone split that keeps less of your work unpaid at any moment. The clause that was missing, now standard. A cap on concentration, if the real failure was that any one client could hurt you this much — the client concentration checker shows the number you should have been watching. One fix, not five: five is a mood, one is a rule.
Write the rule where your rules live: the process file, dated, in the same sitting — the standing habit our guide to running a project retrospective builds after every project, applied here to the one that paid in experience only. Because a bad debt that changes nothing will be repeated, usually at a higher price: the client profile that produced it is still walking through your door at the old settings. The write-off closes the invoice. The rule is what closes the pattern.
5. The emotional bookkeeping
One honest thing remains, and it belongs in a business guide precisely because it changes business behaviour. An unpaid invoice is not only a financial loss; it is a small humiliation that replays — at the desk, at night, whenever the client's name crosses a feed. Carried open, it taxes everything around it. You quote the next client a little defensively. You chase the next invoice a little too hard, or not at all. And you keep a ledger of grudges that no accountant would recognise but every freelancer maintains.
This is the part of the write-off that nobody prices: done deliberately, it closes the account in your head as well as in the books. The decision is made, the letter is sent, the rule is extracted — there is nothing left to rehearse. The freelancers who last are not the ones who never lose money. They are the ones who lose it once, learn the specific lesson, and stop paying interest on it in attention. Write it off in every sense: the ledger, the file and the grudge. Then go and do the work that pays — which was the point of stopping, all along.
A last word on scope. Everything in this guide is general business information, not legal or tax advice. The two moments it deliberately stops — what a write-off does in law, and what it does in your tax position — are professional questions whose answers depend on where you are. Buy those hours of advice when the amount justifies them. The rest — the test, the close-out, the lesson — is yours to run today.

This guide is the last stop on a road the other getting-paid guides walk in order: the reminder ladder in how to ask for late payment professionally, the pattern fix in how to handle a client who pays late every time, and the formal routes in what to do when a client won't pay. Read them forward if you are mid-road; read this one when the road ends. And the prevention sits upstream of all of them — the deposit, the milestones and the terms agreed before the work starts — because the next bad debt is being decided right now, at somebody's signing table, possibly yours.
