How to Spot and Recover Billable Leakage

Billable leakage is the quiet gap between the work you do and the work you get paid for. No single lost half-hour feels significant, but across a team and a year it adds up to real money - often a month or more of revenue that was earned and never invoiced. Here is how to find it and close it.

What billable leakage is

Leakage is billable hours that never reach an invoice. It is different from discounting: with a discount you choose to lower the price; with leakage the work simply disappears from the record before anyone decides anything. It shows up as a low realization rate - you billed less than you could have.

Where it hides

The usual suspects:

• Forgotten time - work reconstructed days later from memory, always rounded down.
• Small unlogged tasks - the five-minute call, the quick fix, the extra revision.
• Rounding down - "call it half an hour" when it was closer to fifty minutes.
• Scope creep - extra work absorbed instead of raised as a change.
• Late timesheets - hours submitted after the invoice has already gone out.

Estimate the size

Guessing understates it. Put rough numbers in the Billable Leakage Calculator: rate, team size, and the minutes each person loses per day. Even 15 minutes a day per person becomes a striking annual figure - and that number is usually what makes the problem worth fixing.

Close the gap

Leakage responds to habit and process, not surveillance:

• Capture time as work happens, not at week's end. This single change recovers most forgotten time.
• Log small tasks too - they are the easiest hours to lose and the easiest to bill.
• Reconcile before invoicing - compare approved hours with the draft invoice. An invoice and timesheet reconciliation worksheet makes the check routine.
• Set a submission deadline so hours land before billing, not after.

Measure it, then keep it closed

Track realization and utilization over time so leakage cannot creep back. If the split between billable and non-billable work is unfamiliar, start with billable vs non-billable hours.
