Time tracking best practices come down to a handful of operating standards: capture time as the work happens, match the detail to how you bill, track billable and non-billable hours, write descriptions you can invoice from, and review entries on a tight cadence. Get those right and the gap between hours worked and hours billed starts to close.
If your team works a 40-hour week but only 28 of those hours make it onto client invoices, you’re not alone. Small accounting practices, law firms, and consultancies all run into the same gap, and the reason rarely comes down to people slacking off. The hours are real. They just slip through the cracks of unclear processes and inconsistent tracking habits.
Clio’s 2023 Legal Trends Report found that lawyers spend only 37% of their workday on billable tasks, roughly 3 hours out of an 8-hour day. Closing that gap rarely means working harder. It means capturing the work already being done, then using the data to price and staff the practice better.
What follows is the full set of standards behind useful time tracking, from what to capture and how detailed entries should be, through to choosing software and getting the team to actually use it.
Why time tracking matters for a small practice
When you only have five fee earners, every misplaced hour shows up in the bank account. The case for taking time tracking seriously rests on four things: protecting earned revenue, defending invoices, making better business decisions, and measuring utilization.
Revenue you’ve already earned
Every untracked hour is money the practice earned but never invoiced. When an accountant forgets to log a 20-minute advisory call, or a lawyer skips a quick email exchange because it didn’t seem worth tracking, that work disappears from the next invoice. Research from the Accountants Law Lab suggests accountants and lawyers who don’t track in real time can lose up to 30% of billable hours to forgotten or underestimated work.
Client trust through transparency
Detailed time entries make invoices defensible. When a client questions a bill, and at some point one always does, you can show exactly what work was performed, on what day, and how long it took. That conversation is much shorter, and much friendlier, when the underlying records are precise.
Smarter decisions about the business
Knowing where the team’s time goes is the only honest way to answer questions like whether junior staff are taking longer than expected on routine work, whether a particular client is consuming more capacity than their fee justifies, or which service lines actually pay. Without the data, these are guesses.
A real view of utilization
The AICPA’s 2023 National MAP Survey found that accounting firms reported a median utilization rate of 59.6%. Utilization, the share of working hours spent on billable work, is the closest thing professional services has to a single health metric, and you can’t manage it without consistent tracking.
Utilization, realization, and collection: the three metrics that matter
Three metrics turn raw time data into a read on profitability. Utilization is the share of available hours spent on billable work. Realization is how much of that billable work actually gets invoiced. Collection is how much of what you invoice gets paid. Each one leaks revenue in a different place, and tracking time is what makes all three visible.
Clio’s Legal Trends Report popularised this framework for law firms, but it applies just as cleanly to accounting and consulting practices. A firm can have healthy utilization yet still bleed money if realization is low, because the hours are being worked and recorded but written down or never billed.
The encouraging news is that the gap is closeable. Clio reports that law firm realization rates climbed from 77% in 2016 to around 86% in recent years, and that improvement came from better time capture and billing workflows rather than longer hours. For consultancies, billable utilization in management consulting averages about 67.7%, with most firms targeting 70-85% depending on role seniority.
MinuteDock is a time tracking and billing platform built for professional services firms, and its Reports give you the billable-versus-total picture these three metrics depend on.
Track time as you work, not from memory
The single most important practice is to record time when the work starts, not when the day is already over. Reconstructing the day at 5 PM is a recipe for underbilling, because memory smooths the edges, and the edges are where billable minutes live.
The Association of Legal Administrators notes that waiting until the end of the day loses around 25% of billable time, and waiting until the end of the week can lose as much as 50%. The fix is to anchor the timer to a moment in the work, so starting it stops being something you have to remember:
- Start the timer when you open the client file in your accounting platform
- Start the timer when you dial a client number, before the call connects
- Start the timer when you draft the first line of a client email
- Stop the timer the moment you switch tasks, not “in a minute”
Most professional time tracking tools, including MinuteDock, let users correct entries when they forget, but corrections should be the exception, not the daily routine.
Match your tracking detail to your billing model
The right level of detail depends entirely on how you bill. Law firms need six-minute precision, accountants usually need clear task-level entries, and consultants need time that rolls up cleanly against project budgets. Pick the level your billing model requires, then apply it consistently across the team.
Law firms work in six-minute increments (0.1 of an hour), and Clio’s billable hours chart is the standard reference for converting minutes. A 7-minute call rounds to 12 minutes; an 8-minute task rounds to 12 as well. Run the timer accurately, then apply the rounding rule at the invoicing stage, not while you track.
Accounting and bookkeeping practices generally don’t need six-minute precision, but they do need clear, descriptive entries that match the service: “Bank reconciliation, Acme Ltd, March,” not “bookkeeping.” Consultants and agencies usually track project budgets rather than billing by the hour, but the underlying data still needs to be consistent so it rolls up. Mixed precision across the team makes reporting useless.
Track all your time, not just billable hours
Track everything, not only the work you can invoice. Billable-only tracking leaves out half the picture: without non-billable time you can’t calculate real utilization, see where capacity is leaking, or work out which admin tasks are eating into client work.
Clio’s analysis of non-billable time found that 48% of non-billable hours go to administrative tasks and 33% to business development. The exact mix differs for accountants and consultants, but the share is consistently large enough to matter. The only way to know your own figure is to capture both sides under a few clear categories:
- billable client work
- internal administration
- business development
- compliance and training
Most practices find the same shape once they look: a handful of non-billable categories soak up a surprising amount of the week, and a few of those are strong candidates for automation or delegation.
Write specific, defensible task descriptions
A good time entry description does two jobs at once: it justifies the charge on a client invoice and it tags the data for internal analysis. Both jobs need specifics, so vague entries like “email,” “meeting,” or “work on Smith account” fail on both counts.
Compare the weak version with one that holds up:
- “Email” becomes “Correspondence with client re Q4 tax planning options”
- “Meeting” becomes “Conference call with opposing counsel re settlement terms”
- “Bookkeeping” becomes “Bank reconciliation and expense categorisation, March 2025”
Good descriptions name the specific matter or project, include the deliverable or outcome, and front-load the important information, since clients often see truncated text on invoices. Setting a simple house style keeps entries consistent across the team, and many corporate clients explicitly require this kind of narrative billing.
Organise work with a client, project, and task hierarchy
Useful reporting needs structure, and most professional services data fits cleanly into three levels:
- Client - who the work is for
- Project or matter - what engagement
- Task - what specific activity
For an accounting practice, that might be Acme Ltd, then 2025 Tax Return, then Prepare Form 1120-S. For a law firm: ABC Manufacturing, then Employment Contract Dispute, then Draft motion. For a consultancy: Beta Corp, then Strategy Refresh, then Stakeholder interviews.
Once entries are structured this way, the same data answers very different questions. How much time has gone into Acme Ltd this year? Which matter types consume the most hours? Are advisory tasks growing as a share of the week? In MinuteDock, the Contact, Project, and Task hierarchy maps directly onto this, and the accounting integrations carry the structure through to invoicing.
Protect focus with one timer at a time
Run one timer at a time. Parallel timers feel efficient until the timesheet stops matching reality, and constant switching carries a hidden cost beyond the lost minutes themselves.
Research from the University of California, Irvine found that it takes an average of 23 minutes and 15 seconds to fully refocus after an interruption. For a fee earner juggling matters, that’s real lost productivity, and the cost compounds when the interruption itself never gets captured. A workflow that protects focus tends to follow the same shape:
- Commit to 30 to 60 minutes on a single client matter before switching
- Use the running timer as a visible reminder of the current task
- When an interruption is unavoidable, stop the current timer cleanly and start a new one for the interrupting work
- Resume the original timer when you return
The timesheet then reflects what actually happened, and most practices discover the team is context-switching far more than anyone realised.
Fix missed time the same day
When you forget to start the timer, add the missing entry the same day. The longer the gap between the work and the entry, the worse the estimate gets, so same-day reconstruction is the difference between a close approximation and a guess.
Check your calendar and sent emails to rebuild the time, account for context-switching honestly, and flag the entry as an estimate in the description if it isn’t precise. Frequent estimates are a signal that the underlying habit needs adjusting rather than the entry rules. The usual fix is a small workflow change: an end-of-day five-minute review, a phone reminder, or a mobile timer so client calls away from the desk get captured in real time.
Set time budgets and track against them
Once a few months of clean data is in place, set time budgets for recurring work and track against them. You’ll know roughly how long a year-end set takes, how many hours a typical contract review needs, or how much discovery a particular matter type involves, and that knowledge makes planning and pricing far less of a gamble.
Budgets do four useful things: they make project planning realistic, fixed-fee pricing defensible, performance issues visible early, and recurring scope problems harder to miss. According to PMI’s Pulse of the Profession report, organisations with mature project management practices see markedly higher rates of on-budget completion, and tracking against time budgets is one of the cleanest ways to get there.
Review and submit time on a tight cadence
Review and submit time daily if you can, weekly at the outer limit. Entries that pile up don’t just delay invoicing, they get less accurate every day, and a monthly catch-up turns billing into a reconstruction exercise.
A tight cadence speeds up invoicing, catches errors while the work is still fresh, and gives partners or managers current data for oversight. A simple policy works well: entries submitted by close of business Friday, approved Monday, invoiced Tuesday. A short weekly review is also the moment to catch missing entries, unclear descriptions, and work drifting outside agreed scope, while the details are still recent enough to fix.
Turn your timesheet into business intelligence
Six months of consistent timesheets is a profitability tool, not just a billing record. The same data that produces invoices answers the questions that decide pricing, hiring, and which clients are worth keeping.
- Which clients are profitable? When time tags cleanly to a Contact, the data reveals which clients consume more capacity than their fee justifies. Sometimes the most pleasant client to work with is the least profitable.
- Which services pay best per hour? Tax prep and bookkeeping can look similar from the outside, but the data usually shows one is significantly more profitable per hour worked.
- How accurate are our estimates? If a fixed-fee engagement consistently runs 14 hours when you quoted 10, that’s a pricing problem you can fix on the next proposal.
- Where does the week actually go? Reviewing weekly time data shows the gap between intent and reality, and where the next process improvement should land.
This is also where revenue leakage becomes visible: an Accelo white paper estimates that more than a third of billable revenue can be lost to untracked meetings, emails, and delayed timesheets. MinuteDock’s Reports visualise time by Contact, service type, and team member, and time-based Goals let you set targets, such as billable hours per week or a billable-to-non-billable ratio, and track against them through the day.
Get your team on board with time tracking
Adoption is won by framing time tracking around what the team gets out of it, not by policing. When fee earners see the data as evidence that their work is profitable, and as the basis for raises, bonuses, and a fairer workload, resistance drops fast. Surveillance framing kills adoption; ownership framing builds it.
A few moves make the difference:
- Explain what’s in it for them. Accurate tracking captures more of their billable hours, reduces invoicing admin, and shows where they need more resources before they’re overwhelmed.
- Make it effortless. If logging a five-minute call takes 90 seconds of admin, people skip it. The tool should require less effort than writing a sticky note.
- Tie it to existing habits. Treat “I always forget to start the timer” as workflow design, not willpower: anchor the timer to opening a file, dialling a number, or starting an email draft, and let end-of-day reviews catch the rest.
- Make it a clear expectation. Have the straightforward conversation that tracking is part of the job, while staying open to two-way feedback on what’s working and what isn’t.
A day in a working time tracking workflow
Here’s what consistent tracking looks like in practice, in a small accounting practice:
- 8:55 AM. Open MinuteDock alongside Xero. Start a timer for “Acme Ltd, monthly reconciliation” before pulling up the bank feed.
- 9:40 AM. Phone rings. Stop the Acme timer, start a new one for “Beta Industries, payroll query,” and log the conversation in the description as you go.
- 9:55 AM. Call ends. Stop the Beta timer. Resume the Acme timer to finish the reconciliation.
- 10:30 AM. Reconciliation done. Start a timer for “Gamma Trust, Q4 review prep” and open the file.
- 12:30 PM. Lunch. No timer.
- 1:15 PM. Pick up where Gamma left off, restart the timer.
- 4:45 PM. Last entry of the day. Stop the timer.
- 4:50 PM. Five-minute review. Anything missing, like an advisory call that didn’t get its own entry? Add it now, marked as an estimate if needed.
- 4:55 PM. Submit the day’s entries, ready to flow into invoicing on Friday.
That’s eight hours of work captured in roughly the effort it takes to write a sticky note, with every minute on the right Contact, against the right service, and a description that holds up on an invoice.
Time tracking tips by profession
The standards above apply across professional services, but each segment has its own quirks worth calling out.
Accountants and bookkeepers
Busy season is the make-or-break test. Standard task templates for recurring work, such as tax return prep, review, and filing, speed up data entry without sacrificing detail. Clear separation between compliance and advisory work is the other high-leverage move, since many practices bill far less for advisory hours than they realise simply because those hours get folded into compliance projects. Tight integration with Xero, QuickBooks, MYOB, or Wave cuts the double-entry that kills adoption faster than anything else. For more, see why time tracking matters specifically for accountants.
Lawyers
Six-minute increments are the standard, and the tool needs to handle the rounding cleanly. Narrative descriptions matter more here than anywhere else; corporate clients often require them, and writing them tends to lift timekeeping quality across the team. Matter-centric tracking is the other essential, so every entry ties to a specific matter number and keeps case costing, billing, and trust accounting clean. Accurate records also aren’t optional from an ethics standpoint in most jurisdictions, since they underpin the demonstration of reasonable fees. For lawyers, these are the software categories worth investing in.
Consultants and advisory firms
Consulting usually means fixed-fee or capped arrangements, which makes project budget tracking the central discipline. Scope creep is far easier to address when you can see actual hours against the original estimate before the engagement runs over. Categorising by service line (strategy, implementation, training) tells you which work is most profitable, and travel-time policy needs to be explicit: full rate, reduced rate, or not at all, applied consistently.
How to choose time tracking software
Most tools can record time. The better test is whether a small practice will keep using one every day, which comes down to speed of capture, integration, reporting, and pricing that scales.
- Speed of capture. Starting and stopping a timer should take a couple of seconds. If logging a short call is a chore, the team will skip it.
- Integration with the rest of the stack. A time tracker that syncs Contacts and entries straight into the accounting platform turns timesheets into invoices in a couple of clicks. For the trade-offs, picking the right time tracking software goes deeper, and accurate billing: how time tracking can transform your invoicing covers the billing payoff.
- Reporting that answers real questions. “Hours by client this month,” “billable versus non-billable by team member,” and “budget consumed by project” should each be one click away.
- Pricing that scales with the team. Per-seat pricing should match how the practice grows, with no surprise tiers when the fifth person joins.
The wider direction of travel supports the investment: in the Thomson Reuters Future of Professionals Report, surveyed professionals expected automation and AI tools to free up several hours per week as adoption matures, much of it in the admin that good time tracking already trims.
Common time tracking mistakes to avoid
Even with the right standards in place, a few patterns regularly drag practices backwards:
- Batch-entering time at week’s end. The entries become educated guesses and consistently undercount.
- Vague descriptions to save time. They cost more later in partner reviews, client disputes, and useless reporting data.
- Skipping small increments. A five-minute client call is still billable, and a month of skipped calls is real money.
- Inconsistent project codes across the team. When people categorise the same work differently, reporting breaks. Define the categories once, apply them everywhere.
- Treating non-billable time as invisible. You cannot improve capacity you never record.
Frequently asked questions
How detailed should time entry descriptions be for client billing?
Detailed enough to justify the charge if questioned. A useful test: if a client saw only this description on the invoice, would they understand what was done and why? Include the deliverable or outcome where it adds clarity, and avoid filler that clutters the entry.
Should the team track administrative and meeting time?
Yes. Tracking only billable hours gives you half the picture. Capturing non-billable time is the only way to calculate real utilization, see where the week goes, and spot low-value activities worth automating or eliminating.
What’s the difference between utilization, realization, and collection?
Utilization is the share of available hours spent on billable work. Realization is how much of that billable work actually gets invoiced after write-downs and discounts. Collection is how much of what you invoice gets paid. A practice can score well on one and poorly on another, which is why all three are worth watching.
What’s the best way to track time across multiple client matters in a day?
Start a new timer each time you switch clients. Three matters in an afternoon means three separate entries, and that granularity is what makes per-client profitability analysis possible. Apply any rounding at the invoicing stage, not while you track.
How often should the team submit time entries?
Daily is ideal, weekly is the outer bound. Most practices run a weekly submission deadline, such as Friday by 5 PM, and approve on Monday so invoicing rolls out the same week the work was done.
What if someone consistently forgets to track time?
Treat it as a habit problem, not a willingness one. Anchor the timer start to an existing action, set phone reminders, and build a quick end-of-day review into the routine. When a gap happens anyway, reconstruct the time from calendar and sent email and mark it as an estimate.
Getting started
You don’t have to overhaul everything at once. Pick one standard this week, such as live tracking instead of memory, clearer descriptions, or a weekly review cadence, and let it embed before adding the next. Small improvements compound quickly.
MinuteDock was built specifically for small professional services firms: simple timers, a clear Contact, Project, and Task structure, and direct sync into Xero, QuickBooks, MYOB, and Wave so the time data flows straight into invoicing.
