We gathered time entry data from hundreds of law firms and asked a simple question: 

“Once a lawyer finishes their work, how long before the time entry actually makes it into the billing system?”

We ended up with nearly 170,000 time entries - spanning family law to corporate M&A, firms of every size, and every major region in the US and Canada. Then we sliced the data by role, geography, practice area, and firm size.

Here's what the numbers say - and what they mean for how your firm thinks about time tracking.

The Average Lawyer Reviews Their Time Entries in 10.4 Hours

The typical timekeeper reviews and releases their entries within a business day - 

• 10.4 hours from draft to approval

• 62% average under 24 hours

• 91% average under one week

That's a lot faster than most of us would expect. 

But the average hides four very different groups of timekeepers - each with different habits, different needs, and different implications for your firm's revenue.

Four Types of Timekeepers (and How to Manage Each One)

The real-time reviewers (35%)

These timekeepers review entries during natural breaks throughout the day. 

Finish a research session, glance at the draft, approve it, move on. 

They don't need managing - they've already built time review into their workflow. Leave them alone.

The daily batchers (26%)

These timekeepers set aside time once a day - usually end-of-day or first thing the next morning - to review everything at once. 

This is a perfectly good habit. Entries are still fresh, details are accurate, nothing slips through. 

If your whole firm operated like this group, you'd have no timekeeping problem.

The weekly reviewers (29%)

This is where things start to cost you. These timekeepers treat time review as a weekly task, and a few days of delay means fading memory, lost details, and billable hours that slip through the cracks. 

Research shows recall accuracy drops significantly after just 24 hours - so a Thursday entry reviewed the following Tuesday isn't a review, it's a reconstruction.

The fix for this group is usually structural. 

They're often attorneys doing long-form work (depositions, document review, due diligence) without natural stopping points. 

Building artificial review checkpoints into their day - between document sets, after each deposition session, at lunch - can move them into the daily batcher category without much friction.

The holdouts (10%)

About 1 in 10 timekeepers routinely take more than a week to review their entries. This is where the real revenue leakage lives - and this group deserves the most attention from firm leadership.

Here's why: 

• The holdouts aren't just slow, they're usually the firm's highest-volume billers.

• A single high-volume attorney sitting on 30 hours of unreleased time moves the firm average more than five timekeepers at 2 hours each. 

• They represent a small share of headcount but a disproportionate share of revenue at risk.

The data says the highest-ROI move for any firm is to identify your 2–3 slowest high-volume billers and work with them directly. 

Firm-wide policies don't move the needle - individual coaching does. More on that below.

Paralegals Review Time 4x Faster Than Attorneys

78% of paralegals release within a day at a typical pace of 5.5 hours. Attorneys? 53% same-day, with a typical review time of 20 hours. Nearly a 4x gap.

Paralegal work is naturally chunked:

• Draft this document

• File that motion

• Coordinate this hearing

Each task maps neatly to a time entry, and reviewing it is a natural next step before moving on.

Attorney work is different

A single matter might involve hours of research, a full day of depositions, and document review that stretches across the week. Entries stack up because the work doesn't have natural stopping points the way paralegal tasks do.

If your firm is struggling with timely time entry, look at your attorney population first. Your paralegals and staff are probably fine.

How Practice Area Shapes Time Entry Speed

Estate law is the fastest practice area. Corporate, M&A, and complex litigation are the slowest. The rhythm of the work determines how naturally time review fits into the day.

Estate and probate work is task-shaped. You draft a will, and then you review the time entry. The task has a clear start and end, which makes reviewing time a natural next step before moving on.

Corporate and M&A work doesn't have those built-in breakpoints. You're buried in due diligence for days at a time, and timekeeping isn't top of mind when you're in the middle of a deal. The 2.7-day average is really a few slow reviewers dragging up a group that's otherwise fine.

Why “Billing Culture” Doesn't Really Exist

We looked at within-firm consistency and found that 45% of firms have widely mixed billing speeds - at the same firm, the fastest timekeeper releases entries hundreds of times faster than the slowest. Only 9% of firms are truly uniform.

Billing culture is mostly individual behavior, not a firm-level thing. Firm-wide timekeeping policies won't fix it. 

You'd get more out of identifying the specific people who are falling behind and working with them directly - especially the high-volume billers sitting on a week of unreleased time.

Geography And Firm Size

Geography plays a role too. Canada and the Midwest are the fastest regions (~66–69% same-day), while West Coast firms have the lowest same-day rate at 47%. 

The gap between the fastest and slowest states is over 10x - same tools, similar work, almost purely behavioral differences.

Large firms are the fastest overall, with a typical review time of 3.9 hours and 79% same-day. 

They tend to have dedicated billing ops staff keeping tabs on the numbers. Small firms move fast when they're motivated, but there's no one nudging you when you're the managing partner, billing clerk, and paralegal rolled into one.

Where do Billable Hours Disappear?

Lawyers rarely forget to log the big stuff. Nobody finishes a two-hour deposition and skips the time entry. Long drafting sessions and client meetings that eat up a whole morning - those make it into the billing system because they're hard to miss.

The time that disappears is the small stuff:

• A five-minute email to opposing counsel between drafting sessions

• That quick phone call you forgot about by lunch

• Ten minutes of research that didn't feel worth opening your billing software for

Any one of these feels trivial. But a lawyer who skips ten five-minute tasks a day is leaving nearly an hour of billable time unrecorded. Over a month, that's real money and it's invisible, because you can't miss what you never knew you lost.

When we compared entries that lawyers typed up manually against entries captured by automated timekeeping tools, the pattern was clear:

• Manual entries were almost all high-value, high-visibility work - the stuff no one forgets to log

• Automated entries caught everything in between - small tasks that individually feel like nothing but collectively represent a significant chunk of a lawyer's day

This is where a tool like Ajax fits. 

• It reads your screen in the background.

• Drafts entries from everything you do throughout the day, so those quick tasks and context switches become entries waiting for your approval instead of lost revenue.

• Screen content is processed and automatically deleted, and nobody else can see what's in your Ajax - not even firm management.

Final Thoughts

The biggest takeaway from 170,000 time entries is that timekeeping speed isn't a firm-level problem - it's an individual one. Most of your timekeepers are probably doing fine. The revenue leakage comes from a handful of holdouts, usually high-volume billers, who sit on entries for a week or more.

The highest-ROI move is almost always the same: find your slowest high-volume billers and work with them one-on-one.

How Legal Firms Do Their Time Tracking [2026 Data Report]

Title Options:

• How Fast Do Lawyers Review Their Time Entries? We Analyzed 170,000 Entries to Find Out

• Automated Timekeeping Captures 36x More Billable Work. Here's the Data

• The State of Time Entry Review: A Data Report From 170,000 Legal Time Entries

• How Law Firms Actually Review Time: Benchmarks From 170,000 Entries

We pulled time entry data from law firms using automated timekeeping and asked a simple question.

Once the software drafts a time entry, how long before someone reviews and releases it?

We ended up with nearly 170,000 time entries - spanning family law to corporate M&A, firms of every size, and every major region in the US and Canada. Then we cut the data by role, geography, practice area, firm size. And manual vs. automated entry methods.

Here's what the numbers say, and what they mean for how your firm thinks about time tracking.

The Average Lawyer Reviews Their Time Entries in 10.4 Hours

The typical timekeeper reviews and releases their entries within a business day:

• 10.4 hours from draft to approval

• 62% average under 24 hours

• 91% average under one week.

That's a lot faster than what most of us would expect from the industry. 

When the hard part (generating the entry) is handled for you, reviewing time becomes a daily habit, not a Friday afternoon project.

Here's how the distribution breaks down:

About 35% of timekeepers release in under 4 hours - reviewing entries during natural breaks or at the end of a work block. Finish a research session, glance at the draft, approve it, move on. 

Another 26% batch their review once a day, usually end-of-day or first thing the next morning.

The 29% who take 1-7 days treat time review as a weekly task. They get it done, but the delay means details fade and billable hours slip through the cracks.

Then there's the bottom 10% - timekeepers who routinely take more than a week. This is where the real revenue leakage lives.

Paralegals Review Time 4x Faster Than Attorneys

Paralegals release time at nearly 4x the speed of attorneys. The gap comes down to how the work is structured.

Paralegal work is naturally chunked:

• Draft this document

• File that motion

• Coordinate this hearing

Each task is a self-contained block that maps neatly to a time entry. You finish the task, you review the entry. There’s a natural rhythm.

Attorney work is different

A single matter might involve hours of research, a full day of depositions, and document review that stretches across the week. Entries stack up because the work doesn't have natural stopping points the way paralegal tasks do.

If your firm is struggling with timely time release, the data says: look at your attorney population first. Your paralegals and staff are probably fine.

How Practice Area Shapes Time Entry Speed

Estate/probate and family law are the fastest practice areas. IP is the slowest. Again, the pattern is about how the work is structured - not who cares more about billing.

Estate and probate lawyers work in discrete chunks. You draft a will, and then you review the time entry. The task has a clear start and end, which makes reviewing time a natural next step before moving on.

Family law has the strongest combination of speed and consistency. 71% of family lawyers average under 24 hours. The work is full of short interactions throughout the day (a quick call with a client, a 30-minute court appearance, a motion filing), and each one creates a natural breakpoint to check your entries.

Corporate, M&A, and transactional work tends to be slower. When you're deep in due diligence for a multi-day deal, there aren't many natural stopping points to think about timekeeping. The 2.7-day average is really a few slow reviewers pulling up a group that's otherwise reasonable.

IP timekeepers are the slowest by a wide margin. Long patent prosecution cycles and deep technical research sessions don't create natural review windows.

Firm Size, Geography, and the Myth of "Billing Culture"

Large firms release the fastest. A typical timekeeper at a firm with 80+ employees reviews entries in under 4 hours. 

But the more surprising finding is that "firm culture" barely exists for this metric.

Firm size

Large firms tend to have dedicated operations staff keeping tabs on billing and the infrastructure to enforce good habits. Small firms move fast when they're motivated, but there's no one nudging you when you're the managing partner, billing clerk, and paralegal rolled into one.

Geography

Canada and the Midwest are fastest. West Coast firms have the lowest same-day rate at 47% - possibly a time zone effect, where longer workdays push end-of-day review into the next morning. The gap between the fastest and slowest states in our data is over 10x. Same tools, similar work. The difference is almost purely behavioral.

The "billing culture" myth

We looked at within-firm consistency and found that 45% of firms are "mixed." Some timekeepers release same-day while others at the exact same firm take a week or more. 

Only 9% of firms are truly uniform.

At a typical firm, the fastest timekeeper releases hundreds of times faster than the slowest. 

So when we talk about "billing culture," we're mostly talking about individual behavior, not firm-level norms. The practical implication is that firm-wide policies are less effective than working directly with the specific timekeepers who are falling behind.

Why Automated Timekeeping Captures 36x More Billable Work

Timekeepers review AI-generated entries at about the same pace they manually enter time.

About half of timekeepers are faster with automated entries, half are faster with manual. An almost perfect split.

The volume gap is where the story lives.

Timekeepers produce 36x more entries through automated capture than they do manually. 

Those manual entries are the ones the lawyer cared enough to type up - the big deposition, the two-hour drafting session, etc. 

The other 36x are the work that would have gone unrecorded:

• The five-minute email to opposing counsel between drafting sessions

• The quick phone call you forgot about by lunch

• The research detour that didn't feel worth logging

This is where a tool like Ajax fits. 

It reads your screen in the background and drafts entries from everything you do throughout the day.

So those quick tasks and context switches become entries waiting for your approval instead of lost revenue. Screen content is processed and automatically deleted, and nobody else can see what's in your Ajax. Not even firm management.

Based on 170,000 entries, the real story is not whether automation makes timekeeping faster. 

It's that it captures work that never would have otherwise been recorded. 

Final Thoughts

The typical timekeeper in our dataset reviews and releases their entries in about 10.4 hours, and 62% get it done within a day. 

Automation doesn't make any individual entry faster to process. 

But on average it captures 36x more billable work that would otherwise go unrecorded. 

And underneath every firm-wide average, there's enormous individual variation that no blanket policy is going to fix.

These firms already use automated time capture, so their numbers likely represent a faster baseline than fully manual firms. If your timekeepers are still reconstructing their days from scratch, the gap between your firm and these benchmarks is probably wider than the numbers suggest.
