Definition
An allowance for doubtful accounts is an estimate of receivables that may not be collected. It is used to recognize expected credit losses.
Example
If you expect 2% of $3M AR to be uncollectible, the allowance is $60k.
How to use it
- Use historical loss rates and adjust for segment and macro changes.
- Keep allowance policy consistent so trends are comparable.
- Reconcile write-offs against the allowance to keep accuracy.
Common mistakes
- Using a single flat rate despite changes in customer mix or macro risk.
- Failing to update the allowance after large write-offs.
Why this matters
This term matters because cash timing and risk are usually the difference between a plan that works on paper and a plan that survives. Use consistent definitions so decisions are comparable over time.
