Billable Leakage

Billable leakage is earned, chargeable work that never reaches an invoice. It hides in forgotten minutes, un-logged tasks, rounded-down time, and discounts applied without a decision - and it quietly lowers revenue and your effective rate.

Where it hides

  • Small tasks captured late or not at all.
  • Billable hours recorded as non-billable by mistake.
  • Write-downs at invoice time that cut realization.

Why it matters

A few untracked minutes per person per day compound into material lost revenue over a year. You cannot recover what you never measured.
