The hours you already worked: where a lawyer's day goes

Ask a lawyer how long they worked yesterday and you will usually get a confident answer. Ask how much of it was billed and the answer is slower, and smaller.

Industry benchmarks put numbers on that gap. They are worth understanding, because the gap is not all one thing, and only part of it can be fixed.

What the benchmarks say

Clio, the practice management company, publishes benchmarks from its Legal Trends research. For 2025 it reports:

  • Utilisation of 38%. On average, about 3.0 hours of an eight-hour working day are recorded as billable work.
  • Realisation of 88%. Of the time recorded, about 2.6 hours' worth is actually invoiced.
  • Collection of 93%. Of what is invoiced, about 2.4 hours' worth is collected.

So from an eight-hour day, roughly two and a half hours turn into money in the bank.

Two cautions. First, Clio's figures come from its own users, mostly firms in the United States, so they are a reference point for South African practice, not a measurement of it. Second, utilisation measures billable time against a standard eight-hour day. Plenty of lawyers work longer than that, which makes the gap bigger, not smaller.

Where the rest of the day goes

Not all of the missing hours are a problem. A working day in a law firm includes:

Work that should never be billed. Supervision, training, internal meetings, business development, managing the practice. A firm that tried to bill all of this would not keep its clients.

Admin that could be lighter. Chasing documents, formatting, filing, and the time spent recording time itself.

Work that was done and never written down. The six-minute call that answered a client's question. The email thread that took a quarter of an hour to settle. The meeting that ran on. The research that started as a quick check. This is the part of the gap that hurts, because the work was real, the client benefited, and the firm was paid nothing for it.

Why billable work goes unrecorded

Most fee earners know the pattern.

Recording is an interruption. When you are in the middle of a matter, stopping to open a system and type an entry feels like a cost. So it gets postponed.

Reconstruction is lossy. By the end of the day, or the end of the week, the large blocks are easy to remember. The small items are not. A diary and a sent-mail folder help, but they never tell the whole story.

Short entries feel petty. Many lawyers quietly decide that a two-minute call is not worth recording, even when a firm bills in six-minute units precisely so that small work can be charged fairly.

Uncertainty becomes write-down. When you cannot remember exactly how long something took, the honest instinct is to round down. Across a month, that adds up.

None of this is carelessness. It is what happens when the system for recording work demands attention at exactly the moments when attention is busy elsewhere.

What actually helps

The firms that capture time well tend to share a few habits:

  • Record close to the work. The sooner an entry is made, the more accurate it is, and the less effort it takes.
  • Make small entries cheap. If recording a two-minute call takes thirty seconds of effort, it will be skipped. If it takes none, it will not.
  • Review, do not reconstruct. Checking a list of drafts at the end of the day is far quicker and more accurate than building a timesheet from memory on Friday.
  • Separate capture from narrative. Getting the fact of the work down is one task. Writing a narrative a client will understand is another. Combining them is part of why recording feels heavy.

This is where software, including AI, earns its place. Thomson Reuters' Future of Professionals report for 2025, a survey of 2,275 professionals in law, tax, accounting and related fields, found that respondents expect AI to free up about five hours a week within the next year. For lawyers, a good share of that is likely to come from exactly this kind of administrative work.

Buying back time

There are two ways to read the gap between hours worked and hours billed.

One is as lost revenue, and it is. A fee earner who records an extra half hour a day of work they were already doing adds weeks of billable time over a year, without working a minute longer.

The other is as lost time. Every hour spent reconstructing a timesheet, or working late to make up for work that was never recorded, is an hour that could have gone to a client, to a difficult matter, or home.

That second reading is why we built Atora. It captures the work as it happens and drafts the entries, so a lawyer's job is to check and approve, not to remember and type. The point is not to make lawyers work more. It is to make sure the hours they already work are the hours they can bill, and to give them back the time they currently spend proving it.
