Write-off
DEFINITION
A write-off is an accounting action that removes an uncollectible asset, most often an unpaid customer invoice, from a company's books and recognizes it as a bad debt expense. It typically happens at the end of the collections process, after dunning, retries, and other recovery efforts have failed.

RELATED TERMS
A write-off is an accounting action that removes an asset, or part of its value, from a company's books because it is judged uncollectible or worthless. For a subscription business, this most often means an unpaid customer invoice or subscription balance that finance concludes will never be collected, so it gets removed from accounts receivable and recognized as a bad debt expense.
Write-offs typically come at the end of the collections process, after dunning emails, payment retries, and sometimes a collections agency referral have failed to recover the balance. A subscription platform such as Recurly sits upstream of this process, where dunning emails and automated payment retries work to recover a failing payment before its balance ever becomes a write-off candidate. Because a write-off directly affects both the balance sheet and reported expense, how and when a company recognizes one is a meaningful piece of financial hygiene, not just a bookkeeping formality.
Why write-offs matter for subscription businesses
Accounts receivable that never converts to cash is not really an asset, even though it may still sit on the books until it is written off. Leaving stale, uncollectible balances on the balance sheet overstates the value of the business and distorts metrics like days sales outstanding. Timely, consistent write-off policies keep financial statements accurate and help finance teams tell the difference between revenue that is simply late and revenue that will never arrive.
For recurring revenue businesses specifically, write-offs are closely tied to involuntary churn, the loss of subscribers due to failed payments rather than an active cancellation decision. A rising write-off rate, calculated as written-off receivables divided by total receivables or total billed revenue over a period, is often an early signal that payment failure handling, card updating, or dunning cadence needs attention before the problem shows up in retention metrics.
How write-offs work
Collections and dunning efforts are exhausted or judged not worth continuing.
Finance determines the specific balance is uncollectible.
Under the direct write-off method, the company debits bad debt expense and credits accounts receivable for that specific amount at the time it is deemed uncollectible.
Under the allowance method, which is generally preferred under GAAP, the company has already estimated expected uncollectible accounts and built an allowance for doubtful accounts (a contra-asset account). The specific write-off is then charged against that existing allowance rather than creating a new expense entry at that moment.
The receivable balance is removed from the books, and if using the allowance method, the allowance balance is reduced accordingly.
Write-off vs allowance for doubtful accounts
A write-off and an allowance for doubtful accounts are related but distinct. The allowance is a forward-looking estimate, a reserve a company sets aside in advance based on historical collection patterns, aging of receivables, and credit risk, to anticipate that some portion of receivables will not be collected. A write-off is the specific, after-the-fact action of removing a particular balance once it is confirmed uncollectible. Well-run finance teams size the allowance so that actual write-offs, when they happen, are absorbed by the reserve rather than creating an expense surprise.
A write-off is also distinct from a refund or a credit. A refund returns money that was already successfully collected. A credit adjusts a future invoice, often to resolve a dispute or make a goodwill gesture. A write-off addresses money that was billed but never collected at all.
Benefits and examples
Maintaining a disciplined write-off process gives finance and revenue teams several concrete benefits:
Accurate reporting: assets on the balance sheet reflect what is realistically collectible, which supports better forecasting and investor or lender confidence.
Clean churn analysis: separating write-offs driven by failed payments from voluntary cancellations makes retention and churn metrics more meaningful.
Better collections tuning: tracking the write-off rate over time highlights whether dunning, retries, or credit policies need adjustment before losses grow.
Audit readiness: a consistent policy for when and how balances are written off, backed by documentation, simplifies external audits and revenue recognition reviews.
As an illustrative example, suppose a subscription company bills $500,000 in receivables over a quarter. Historical experience suggests 2% of receivables in this aging bucket are ultimately uncollectible, so finance records a $10,000 allowance for doubtful accounts ($500,000 x 2%). Later that quarter, a $1,200 invoice from a customer whose card repeatedly failed and who never responded to dunning is confirmed uncollectible. That $1,200 is written off against the existing allowance: the allowance balance drops from $10,000 to $8,800, and accounts receivable drops by the same $1,200, with no new hit to expense at the moment of write-off because the loss was already anticipated.
Common mistakes with write-offs
Writing off a balance too early, before reasonable collection and retry efforts, such as dunning sequences or card updater services, have been exhausted.
Blending voluntary cancellations together with failed-payment churn when analyzing write-off trends, which hides the real driver of losses.
Failing to reconcile the allowance for doubtful accounts against actual write-off history, which leads to a reserve that is too small or unnecessarily large.
Frequently asked questions
What is the difference between a write-off and a chargeback? A write-off is a company's own decision to remove an uncollectible balance from its books after collection attempts fail. A chargeback is initiated by the customer's card issuer, reversing a payment that was already collected, typically due to a dispute or suspected fraud.
Does a write-off affect previously recognized revenue? Generally no. A write-off is a balance-sheet and expense event that addresses cash that was never collected; it does not usually reverse revenue that was properly recognized. Some businesses do reassess whether revenue should have been recognized at all if collectibility was doubtful from the outset, which is a separate revenue recognition question.
How is a write-off rate calculated? It is typically written-off receivables divided by total receivables, or by total billed revenue, over a given period, expressed as a percentage.
Can a written-off balance ever be recovered? Yes. If a customer later pays a balance that was already written off, the company records a recovery, which reverses the earlier write-off entry, usually by re-establishing the receivable and then recording the cash collection.
