Bad Debt: When to Write Off an Unpaid Invoice

Not every unpaid invoice is worth continuing to pursue. At some point, the time and cost of collecting exceeds what's actually owed — and recognizing that point, rather than chasing indefinitely, is a normal, unremarkable part of running a business.

Recognizing when to stop

A few signals suggest it's time to write an invoice off rather than continue pursuing it:

• The cost of pursuing it exceeds the amount owed — a collections agency's cut, legal fees, or simply your own time can make further effort a net loss even if you'd technically "win."
• The client is genuinely insolvent — bankrupt, dissolved, or otherwise unable to pay regardless of what pressure is applied.
• You've exhausted the reasonable steps — follow-up, a collection letter, maybe a collections agency or small claims attempt — without success, and further escalation isn't realistic for the amount involved.

There's no universal dollar threshold; it's a judgment call weighing the specific amount against the realistic cost and odds of recovery. Our bad debt percentage calculator can help you see what proportion of your credit sales bad debt actually represents, which is often more useful for decision-making than looking at any single invoice in isolation.

What "writing it off" actually means

Writing off a bad debt means removing it from your accounts receivable as money you still expect to collect — you're not pretending the client doesn't owe it, you're acknowledging that continuing to count it as an asset on your books no longer reflects reality. This is a bookkeeping and, in many jurisdictions, a tax matter — many places allow bad debt to be deducted, which is worth checking with an accountant familiar with your local rules.

It doesn't mean you can't still collect

Writing an invoice off for accounting purposes doesn't waive the debt or prevent you from pursuing payment later if circumstances change — a client's financial situation improves, or new information makes collection viable again. It's a statement about how you're recording it now, not a permanent decision to never revisit it.

Prevention matters more than the write-off itself

A single bad debt is a normal cost of doing business. A pattern of them — a rising bad debt percentage over time — is a signal worth investigating: are you extending credit to clients who shouldn't have received it, or is the process for catching problems early (see reducing late payments) not working the way it should?

Writing off a debt isn't a failure — continuing to carry an invoice you realistically won't collect, and treating it as an asset it no longer is, is the actual mistake.
