Open calculator : Unrecorded Billable Hours CalculatorUse a consistent reporting period
Start with the same customer cohort, currency, date cutoff, and definition of billable value. Deduct documented cancellations, credits, and other legitimate exclusions before treating a difference as a recovery opportunity.
Decide what to check next
Check whether the difference comes from recording, invoicing, collection, or timing. Model a realistic recovery share and compare it with the incremental cost of recovering that value. Keep revenue, recovered cash, and profit separate.
