Billable hours are simple to define and maddening to capture. Every lawyer knows what they are; almost every lawyer loses some of them between doing the work and recording it. This guide covers the definition briefly, then spends its time where the money is: how lawyers actually track billable hours, and how to build a tracking practice that doesn’t leak.
What Are Billable Hours?
Billable hours are the working hours a lawyer can charge to a client: time spent advancing a specific matter, recorded against that matter in increments (usually tenths of an hour) and billed at the agreed rate. Research, drafting, court appearances, depositions, and substantive client communications are billable. Non-billable hours are everything else the job requires that no client pays for: administration, business development, training, and the firm’s own management. The ratio between the two (utilization) quietly determines a firm’s economics, which is why tracking both kinds matters.
How Do Lawyers Track Billable Hours?
Four generations of tracking, all still in use somewhere:
- Memory and paper. Legal pads and end-of-week reconstruction. Still surprisingly common, and the most expensive method a firm can use: reconstructed time is undercounted time.
- Spreadsheets. Better than paper, but disconnected from billing, so every entry is typed twice and nothing prevents gaps.
- Timers in billing software. The current standard: start a timer as a task begins, switch timers as work switches, and the entry lands on the matter with the time already measured. Mobile apps extend this to court, depositions, and the drive between them.
- Assisted capture. The emerging layer: systems that reconstruct a draft of the day from calendar entries, emails, documents touched, and calls made, for the lawyer to confirm and describe. The lawyer still owns accuracy; the system stops the forgetting.
Wherever a firm sits on that ladder, the pattern is the same: the closer the recording sits to the work, the more hours survive.
How to Track Billable Hours Without Losing Them
- Record at the task, not the day. One entry per task with its own description, entered when the task ends. Batch reconstruction is where hours die.
- Run a timer by default. Especially for the fragmentary work (calls, emails, quick reviews) that memory rounds down to zero.
- Capture away from the desk. Court time, travel time on client business, and hallway conferences are billable where the engagement allows; log them from a phone before the next thing starts.
- Track non-billable time too. It’s the only way to see utilization honestly and to find work that should move to staff.
- Close each day with a two-minute audit. Compare the day’s calendar and the sent email against the day’s entries. Anything unrepresented gets entered now, while it’s still true.
- Let the firm enforce the floor. Daily entry expectations, missing-time reports against required totals, and weekly closeout of prior entries turn individual discipline into firm-wide reliability.

From Tracked Hours to Collected Revenue
Tracking is the first half; the second half is making tracked hours turn into cash. That means prebill review that trims deliberately rather than reflexively, statements that go out on schedule, and reporting that shows each timekeeper’s recorded hours, realization, and collections side by side. Orion’s Time Management, iOrion mobile capture, ePrebill Manager, and Financial Management reporting close that loop for mid-size firms. See it at orionlaw.com or request a demo.
