The invoice is correct.
It's just missing a third of the work.
Revenue doesn't leak in one big hole — it leaks through untracked hours, late invoices, and quiet write-offs. One team found $200K they simply never billed, sitting in a spreadsheet nobody was forced to check.
The 60-second leak estimate
Honest numbers only — this is for you, not a pitch deck.
Estimated annual leakage: $163,200
Assumes ~50% billable utilization and 48 working weeks. The point isn't precision — it's whether the number is bigger than a tool would cost.
Plugging it isn't about trying harder
Spreadsheets fail because they rely on someone remembering to check. The fix is a workflow that can't be skipped.
Capture at the source
Time logged where the work happens, not reconstructed Friday at 5pm.
No stage-skipping
Work → review → invoice is a pipeline, not a suggestion. Nothing reaches "done" without a billing state.
Stale-invoice alarms
Work older than X days without an invoice surfaces itself instead of expiring quietly.
We set this up on the tool you already have (Harvest, BigTime, Accelo) or a lighter stack if you've outgrown them.
