Allowance for doubtful accounts

Definition

An allowance for doubtful accounts is a provision netted against accounts receivable for the amount a business realistically expects not to recover, reducing debtors to their collectable value.

In plain terms

Not every invoice gets paid. This allowance builds that reality into the accounts before a specific debt actually turns bad.

Why it matters for your company

A sensible allowance stops receivables (and profit) being overstated, which lenders test in due diligence. When a debt is confirmed lost it becomes a bad debt write-off. See aged debtors.

In practice

Picture a small UK limited company selling on trade credit to a spread of business customers. At each accounting period the finance function reviews the sales ledger and judges, invoice by invoice or by category, which balances look genuinely at risk of non-payment — a customer that has gone quiet, disputed the invoice, or shown signs of financial distress. Rather than waiting for a debt to be confirmed lost, the company books an allowance now, so the balance sheet shows debtors at a value the directors can stand behind.

This is a judgement call, not a mechanical exercise. Two similar-looking companies can reach different allowances for the same aged balance depending on what they know about a particular customer's circumstances, payment history and sector conditions. Good practice is to review the allowance regularly rather than leaving it static, and to document the reasoning so an auditor, a lender or a future director can see why a given estimate was made.

How lenders read it

When a lender reviews a limited company's accounts, the allowance for doubtful accounts is one of the signals used to judge how realistic the reported receivables actually are. A company that never carries any allowance despite an ageing sales ledger can prompt more questions, not fewer — it suggests either genuinely excellent collections or an optimistic set of accounts. Conversely, a sensible, consistently applied allowance policy tends to read as a sign of financial discipline.

A common pitfall is treating the allowance as a one-off adjustment made only when preparing statutory accounts, rather than as an ongoing part of managing the sales ledger. Businesses that revisit the estimate only annually can find it swings sharply from one period to the next, which is itself something a lender or director may want explained. Tying the review into routine aged debtors reporting helps keep the figure current and defensible.
