What Is Passive Time Tracking for Lawyers?
Passive time tracking is software that records billable work in the background as it happens and turns it into draft time entries, with no timers and no timesheet reconstruction. A lawyer works a normal day, and the entries are waiting at the end of it.
Here's the short version of how it works. The software runs on your computer and draws from two places: the screen itself, and the tools already open on it like email, calendar, and phone. It reads what you're doing, groups the scattered pieces of one matter into a single entry, and predicts the client and matter each one belongs to. Then it writes a draft and hands it to you to review and release. Whether a tool reads the screen or only pulls activity through app APIs is a real dividing line, and we cover it here. For the mechanics end to end, see the deeper guide to how this works.
Passive vs active vs automatic time tracking
Three terms get used for the same corner of the market, and they don't mean the same thing.
Active time tracking is the traditional method. You start a timer when a task begins and stop it when you finish, or you type the entry in by hand later. It's accurate when you actually do it, and the whole problem is that people don't, especially for short calls and one-off emails.
Automatic time tracking is the umbrella term, and it's the loosest of the three. Vendors hang it on everything from a timer that reminds you to start it to full background capture. When a tool calls itself automatic, the question worth asking is how much the lawyer still has to do.
Passive time tracking is the strict end of that range. The lawyer does nothing during the day: no timer to start, no note to leave for later. Work is captured as it happens, and the first time a person touches it is at review, when the drafts already exist. That's the line that separates passive from the rest.
What passive tracking changes in practice
The first change is recovered time. Under-capture runs 5 to 15% at most hourly firms, and it sits in exactly the work a timer never catches: the eight-minute phone call, the email fired off from a phone between meetings. Passive capture records that work because it isn't waiting on anyone to remember it.
The second change is timing. Entries exist by the end of the day they describe, not days after the fact. A lawyer reviews a day that's still fresh, so the review is quicker and the narratives closer to what happened.
The third change is quieter and lands on the billing team. When time is already in the system, the people who run pre-bills spend less of the month chasing missing entries. The work of the billing cycle moves from collection toward review.
What to check before you adopt one
Passive capture means the software reads a lawyer's whole screen, so a few questions matter more here than with a timer app.
Who can see the captured activity? Press this one hardest. At Ajax, draft entries and the activity behind them are private to each timekeeper until that person releases them. Firm management sees rolled-up reporting, capacity and unreleased hours across the firm, never another lawyer's screen or unreleased drafts. Ask every vendor to tell you precisely who can see what.
What gets deleted, and when? Captured activity should not sit around indefinitely. Look for encryption in transit and at rest, raw capture that is deleted automatically on a rolling basis, and contractual bans on any AI subprocessor training on your firm's data.
Where do the finished entries go? You want a direct write into your billing system rather than a CSV you re-import by hand. With Ajax, released entries flow through direct integrations into Clio, MyCase, PracticePanther, SurePoint, Filevine, Centerbase, and Soluno, and Ajax is compatible with most other billing systems as well. Whatever you run, make the vendor show you the round trip.
FAQ
Is passive time tracking the same as automatic time tracking?
Passive time tracking is the strictest form of automatic time tracking, the version with no timers at all. Automatic is the umbrella term, and some tools under it still ask the lawyer to start a timer or confirm entries during the day. Passive tools remove every one of those steps until review.
Is passive time tracking accurate enough to bill from?
Yes, because the entries stay drafts until a lawyer reviews and approves them, so nothing reaches an invoice unchecked. And since the work is captured as it happens, the underlying times tend to be more accurate than a figure written up from memory later.
Is passive time tracking private?
It can be, and at Ajax it is. Draft entries and the captured activity behind them are private to each timekeeper until that person chooses to release them, and firm management sees rolled-up reporting only, never another lawyer's screen or unreleased drafts. Access and retention rules vary by vendor, so confirm them before you roll anything out.
