At FWO Chartered Accountants we work exclusively with SME law firms across Australia to help them become financially well organised. One of the simplest, yet most powerful profitability levers we see in every engagement, is often overlooked: the accurate capture of billable time. It is not about working more. It is about billing for the work already being done.
The $3.7 billion problem in small law
The scale of the missed-billing problem in Australian small law firms is much larger than most principals realise. A 2021 Smokeball survey of more than 134 Australian small law firms, reported by InfoTrack, found that small law firms bill just 2.02 hours per day on average and that 46% of firms estimate that they miss up to a quarter of their billable work. The aggregate loss across small law firms in Australia was estimated at as much as $3.7 billion.
The picture is consistent with wider industry commentary. A 2026 LexUnit review states that the average utilisation rate for Australian lawyers sits at around 30-40%, meaning only about 2.5 to 3 hours in an 8 hour day typically make it onto a bill. Most of the missing time is not idle time. It is billable work that never gets captured because time entry is deferred, forgotten or reconstructed later.
This is the exact problem the 45-minute exercise below is designed to solve. It is not a call to work longer hours. It is a call to capture the hours already being worked.
The maths on 45 minutes
The economics of billable time recovery scale quickly. Consider a firm of 10 fee earners, each working 230 days a year at an average rate of $300 per hour. Reclaiming 45 minutes of otherwise-lost billable time per day, per fee earner, adds:
- Approximately 173 additional billable hours per person, per year.
- $51,750 in extra revenue per person, per year.
- Over $500,000 in additional annual revenue for the firm.
The gain does not require hiring, marketing, price rises or a single extra file. It requires the same fee earners capturing more of the work they already do. That is why we treat daily time discipline as one of the highest-return levers in a law firm’s operating model.
How to find those 45 minutes
The five habits below are the foundations, what each looks like in practice, and what it takes to make it stick:
- Daily time entry: Capture time as you go, not at day’s end.
Contemporaneous time entry captures 20-40% more billable time than end-of-day reconstruction, according to LexUnits’ 2026 benchmark industry guide. The reason is simple: memory fades. A phone call at 10:03 that ran for 7 minutes, gets rounded down to 6 minutes of time by 5pm. Multiplied across 240 days of the year, that is where the 45 minutes hides.
The habit is boring, but the pay off is not. Capture time as tasks close, in the practice management system, in 6 minute increments. Every time you touch a matter, log it.
- Plan weekly workflows: spend the right time on the right matters.
Time capture is a symptom problem. The underlying discipline is knowing what work should be happening this week and holding to it. A short Monday planning session per fee earner, reviewing open matters, priority deadlines and revenue targets for the week, reduces the context-switching that eats billable capacity. It also surfaces matters that have gone quiet before they turn into WIP write-downs.
- Reduce admin: minimise non-billable distractions.
Administrative work is the largest reported source of lost time in small firms. In the Smokeball survey reported by InfoTrack, administrative work was identified as the top time drainer at 35%, followed by emails at 25% and phone calls at 24%. Not all of that is avoidable, but a meaningful share is. Documented templates for recurring correspondence, delegated intake and file setup, and clear routing of general enquiries to the practice manager all move admin off the fee earner’s desk.
- Set clear expectations: make time targets visible
Utilisation improves fastest when it is measured and shared. Fee earners cannot hit a target they cannot see. MiNumbers gives firms visibility over fee earner performance and productivity by connecting payroll, timesheets and billing data. Used well, that visibility makes targets easier to track across the week and month, alongside metrics such as average rate, lock-up and performance against budget. When performance is visible, the habit tightens without a partner conversation being required every week.
Australian boutique and mid-tier firms typically target 5 to 6.5 hours per fee earner per day. Top-tier firms sit higher. Where your firm should target depends on practice mix and matter complexity, but the target must exist and it must be visible.
- Educate your team: connect time to profit and career progression
Junior fee earners, particularly in their first few years of practice, often need help understanding how directly time entry discipline affects the firm’s profitability and their own development. A short internal session explaining how average rate, utilisation and realisation combine to fund salaries, bonuses and career advancement changes the conversation. Time entry stops being a compliance task and becomes a professional habit tied to career outcomes.
Why daily time entry beats end-of-day reconstruction
The change that produces the largest recovery in most firms is moving from end-of-day time reconstruction to contemporaneous time capture. Three effects compound:
Recall accuracy. Time recorded as the work happens is more complete and more accurate than time reconstructed at 6pm. LexUnits’ review put the recovery band at 20% to 40% of billable time.
Realisation rate. Time that is captured accurately and billed promptly is more likely to survive pre-bill review and client scrutiny than stale WIP. As WIP ages, it becomes harder to justify, easier to discount and slower to convert into cash.
Cash flow. Contemporaneous time capture accelerates the billing cycle, which helps reduce lock-up days and improve working capital. Time capture and cash gap are closely connected: one starts when work is recorded, the other shows up when that work has not yet turned into cash.
What gets in the way: common barriers and fixes
The reasons firms struggle to sustain daily time entry are usually a small set of familiar patterns. Each has a straightforward fix.
Barrier: Fee earners see time entry as bureaucratic. Fix: Show the direct connection to profit, bonuses and career progression. Publish the numbers.
Barrier: The practice management system is clunky. Fix: Use the built-in time capture tools in Smokeball, Actionstep or the practice management system your firm uses, including automatic tracking, timers, mobile capture and activity-based time suggestions where available, so time entry takes seconds, not minutes.
Barrier: Discretion in write-offs undermines the habit. Fix: Centralise billing decisions and remove write-off discretion from individual fee earners. We covered the mechanics in Discretion: The Silent Killer of Law Firm Profit.
Barrier: Fee earners are unclear on what is billable. Fix: Publish a short guide covering client calls, emails, research, drafting, review, supervision of juniors and file management. Anything client-related is billable unless the fixed fee scope says otherwise.
Barrier: No visibility of daily targets. Fix: Dashboards. Weekly reviews. Monthly benchmarking against firm and industry targets.
What good time capture looks like
For Australian firms, the LexUnits 2026 benchmark ranges are a useful reference point for what disciplined firms look like:
- Top-tier: 6.0-7.0 billable hours per day, 1,400-1,700 hours per year.
- Mid-tier: 5.5-6.5 billable hours per day, 1,300-1,550 hours per year.
- Boutique / specialist: 5.0-6.0 hours per day, 1,200-1,450 hours per year.
- Suburban / sole practitioner: 4.0-5.5 hours per day, 1,000-1,300 hours per year.
Utilisation rate matters as much as raw hours. LexUnits states that many lawyers sit at around 30% to 40% utilisation, meaning only 2.5 to 3 hours of an 8-hour day make it onto a bill. A firm aiming for disciplined performance should set utilisation targets that reflect its practice mix, seniority levels and matter complexity, then make those targets visible.
We identify average rate and revenue lock-up as the two numbers that drive law firm profitability and cash flow. Fee earner productivity, utilisation and billing performance feed into those numbers. Improving time capture can lift average rate; improving billing discipline can reduce lock-up. Improving both compounds the result.
How FWO helps law firms recover billable time
We work with SME law firms across Australia to improve the financial visibility, discipline and accountability behind better time capture. A typical engagement may include:
- Reviewing current performance across utilisation, average rate, lock-up, billing efficiency and fee earner productivity through the Grow Your Firm advisory framework.
- Using MiNumbers to connect time, billing and payroll data, giving firm leaders clearer visibility over fee earner performance, capacity and performance against budget.
- Working alongside practice management systems such as Smokeball and Actionstep to interpret practice data and identify where billing behaviour, collections and cashflow timing can improve.
- Supporting partners with structured reporting, regular conversations and accountability rhythms that turn time capture into a durable habit.
- Connecting time discipline to the broader financial picture, including profitability, cash flow forecasting, partner expectations and, where relevant, succession planning.
The work is not simply a technology purchase. It is a change in daily rhythm. Firms that commit to disciplined time capture can start reclaiming lost billable time without hiring more people, increasing prices or winning extra files.

Frequently Asked Questions
How many billable hours per day should a law firm target?
A law firm should target billable hours based on its firm type, practice mix, matter complexity and seniority profile. Australian benchmark ranges published by LexUnits in 2026 suggest 6 to 7 billable hours per day for top-tier firms, 5.5 to 6.5 for mid-tier firms, 5 to 6 for boutique and specialist firms, and 4 to 5.5 for suburban and sole practitioners. The right target should be explicit, realistic and visible to fee earners.
How much revenue can a law firm recover by improving time capture?
A law firm can recover significant revenue by improving time capture because small daily gains compound quickly. For a firm of 10 fee earners working 230 days a year at an average rate of $300 per hour, recovering 45 minutes of missed billable time per fee earner per day adds around 173 hours per person per year, or approximately $51,750 in revenue per person and more than $500,000 for the firm. Every practice has its own numbers, but the commercial pattern is consistent.
What is the average utilisation rate for Australian lawyers?
The average utilisation rate for Australian lawyers is reported by LexUnits as around 30% to 40%, meaning only about 2.5 to 3 hours of an 8-hour day typically make it onto a bill. Firms should compare that benchmark against their own targets, practice mix and team structure to identify where billable time may be leaking.
Does daily time entry actually capture more billable time?
Daily time entry does capture more billable time when fee earners record work as it happens instead of reconstructing the day later. LexUnits states that contemporaneous time recording captures 20% to 40% more billable time than end-of-day reconstruction.
What are the biggest barriers to daily time entry in law firms?
The biggest barriers to daily time entry in law firms are usually cultural, operational and visibility related. Fee earners may see time entry as administrative, the practice management system may feel clunky, billing discretion may undermine the habit, fee earners may be unclear on what is billable, and targets may not be visible. These barriers can be addressed with clearer billing guidance, better use of practice management tools, centralised billing discipline and regular visibility over performance.
How does time capture affect law firm profitability?
Time capture affects law firm profitability because time that is not recorded cannot be billed, reviewed, collected or measured properly. FWO identifies average rate and revenue lock-up as the two numbers that drive law firm profitability and cash flow. Fee earner productivity, utilisation and billing performance feed into those numbers, so improving time capture can lift average rate, reduce leakage and support healthier working capital.
