How do I decide when to write off an invoice vs. escalate to collections?
When to write off an invoice vs. escalate to collections — how to make the call
Short answer
The core tradeoff is recovery probability multiplied by balance size versus the cost of pursuing it. For balances under $300, write-off is almost always more economical than agency fees or small claims. For balances over $2,000, escalation is usually worth it if the invoice is under 180 days old. Between those points, your relationship with the client and the likelihood of future business should weigh in.
Start with a quick expected-value calculation: (estimated recovery probability) × (balance) − (cost of collection effort). A $400 invoice at 40% collection probability has an expected value of $160. If small claims filing costs $75 and takes 4 hours of your time at a $100/hr opportunity cost, you're spending $475 to recover an expected $160. That's a loss. The math doesn't mean give up — it means set your threshold and act systematically, not emotionally.
Recovery probability is mostly a function of invoice age. Industry benchmarks suggest invoices collected within 30 days have 90%+ recovery rates; at 90 days that drops to roughly 70%; at 180 days it's often below 50%; beyond a year, recovery rates can fall below 25%. These are population averages — your specific client's situation matters too, but age is the most reliable predictor.
Balance size determines which escalation path is available. Under $300: write off or send one firm demand letter and move on — agency fees and court costs make pursuit uneconomical. $300–$2,000: small claims court is the most cost-effective escalation; most states include this range, no lawyer required. $2,000–$10,000: collection agency on contingency (25–50%) or small claims depending on state limits. Over $10,000: collection agency or civil litigation, with legal counsel recommended above $5,000.
Client relationship has a legitimate place in the decision. A client who owes $800 on a first invoice but has $50,000 in annual potential volume is a different calculation than a one-time client with no future business. Many business owners write off small amounts from good clients as a relationship investment — once. The same client who is late twice gets tighter terms (net-15, deposit required) or a credit hold.
Write-off isn't failure — it's a business decision. Once you've passed your escalation threshold, write the invoice off, document your collection attempts for the tax deduction (bad debt expense under accrual accounting), and focus your energy on clients who pay. Sunk-cost reasoning — 'I already spent so much time on this' — is one of the behavioral biases that keeps business owners chasing uncollectable debt long past the economic break-even point.
