Up to 40% of Billable Time Disappears Before It Reaches an Invoice.
Attorneys reconstruct time at the end of the day — or the week — from calendar entries, emails, and memory. Every gap between the work and the entry is revenue that never gets billed. The longer that gap, the more that vanishes.
LeanLaw eliminates the gap entirely. One-tap timers start the moment the work starts — on desktop, on mobile, even in the courtroom. Every entry lands directly in the billing queue, assigned to the right matter, ready to invoice.
- Start and stop timers from any device in one tap
- Multiple simultaneous timers for multi-matter days
- Enter time manually or by voice — whichever is fastest
- Time entries route to billing queue automatically
- WIP reports show every unbilled minute by attorney and matter
Multiple simultaneous timers — switch matters without losing a second
Every Way Attorneys Work. Every Minute Captured.
No two attorneys bill the same way. LeanLaw supports every time-entry method — live timers, retrospective entry, voice notes, and bulk edits — so every attorney captures time the way that works best for them.
Start Billing the Moment Work Starts
A single tap starts a timer on any device. Time is tracked in seconds and syncs automatically to the cloud — so the number on your billing queue is always exact, not rounded. Pause, switch matters, or run multiple timers simultaneously.
Track Time From Anywhere
Full-featured time tracking on every smartphone and tablet. Log time in the courtroom, on client calls, between meetings, or from the car — no excuse for a missed entry.
Manual and Retrospective Entry
Prefer entering time at the end of the day? Type it in manually with duration, narrative, matter, and billing code. Bulk-edit multiple entries at once for attorneys who batch their time.
Custom Rates Per Attorney and Matter
Set default billing rates by attorney and override them per matter. Flat-fee work? Track time against the budget without it appearing on the invoice. Every rate scenario is supported.
See Every Unbilled Minute in Real Time
Work-in-progress reports show everything that has been worked but not yet invoiced — by attorney, by matter, by practice area. Nothing hides in a spreadsheet.
Rich Entries That Clients Respect
Add activity codes, task codes, and billing narratives to every entry. UTBMS and LEDES codes for e-billing clients are supported out of the box — no manual coding after the fact.
Surface Missed Hours From Your Calendar
LeanLaw connects to your calendar — including Microsoft Office 365 — so you can review calendar events and convert meetings, calls, and hearings into billable time entries. Nothing that happened gets left behind.
Legal Time Tracking Software Built for Law Firms
LeanLaw is legal time tracking software purpose-built for law firms — one-tap timers, matter-level time capture, and mobile entry that syncs directly to QuickBooks Online. Unlike general-purpose time trackers, every entry in LeanLaw carries the billing context law firms need: timekeeper, client, matter, billing code, and rate — ready for the billing queue the moment the timer stops.
As law firm time tracking software, LeanLaw replaces the spreadsheets, sticky notes, and end-of-week memory reconstruction that cause up to 40% of billable time to leak before it ever reaches an invoice. Firms that switch to LeanLaw recover an average of $61,000 in leaked revenue per attorney each year — because time is captured the moment it happens, not guessed at later.
- Purpose-built for law firm billing, not generic project time
- Matter- and client-level time tracking out of the box
- One-tap timers on desktop and mobile
- Live sync to QuickBooks Online — no export, no re-entry
What is the best legal time tracking software for a law firm?
The best legal time tracking software for a law firm captures time at the matter level, works on mobile, and syncs directly to your accounting system without manual export. LeanLaw is legal time tracking software built specifically for law firms on QuickBooks Online — one-tap timers, automatic billing-queue routing, and real-time sync recover an average of $61,000 in leaked revenue per attorney each year.
What software should a small law firm use to track billable hours?
Small law firms should use law firm time tracking software designed for legal billing rather than generic project-time tools, since legal billing requires matter assignment, timekeeper rates, and trust-accounting-aware invoicing. LeanLaw gives small firms one-tap mobile timers, manual and retrospective entry, and direct QuickBooks Online sync — so a solo or small-team firm can capture every billable hour without adding administrative overhead.
Is legal time tracking software different from regular time tracking apps?
Yes. Legal time tracking software adds law-firm-specific fields — matter, client, billing code, UTBMS/LEDES codes, and billing rate by attorney — that general time trackers don't support. LeanLaw's law firm time tracking software routes every entry straight into the billing queue and QuickBooks Online, so time capture and invoicing share one connected system instead of requiring a manual handoff between tools.

Time Entries That Flow Straight Into Your Books.
Most legal billing tools require a manual export to get time data into QuickBooks. LeanLaw is built natively on QuickBooks Online. Every invoiced time entry and expense posts to your general ledger automatically — no exports, no reconciliation, no lag.
LeanLaw is not a practice management system. It is a legal revenue operations platform — purpose-built to handle the financial side of law: time capture, billing, trust accounting, and collections. That focus is why 1,000+ firms pair it with QuickBooks Online instead of an all-in-one tool that tries to do everything adequately but nothing exceptionally.
- Every invoice syncs to QuickBooks Online AR in real time
- Matter codes map to QuickBooks classes and customers automatically
- Expense entries post to the correct chart of accounts
- Trust payments and retainer applications reconcile instantly
- Your bookkeeper sees everything in QuickBooks — no second system

LeanLaw Time & Expense Tracking — Common Questions
How does LeanLaw time tracking work?
LeanLaw provides one-tap timers on desktop and mobile. Attorneys can start a timer from any device, add a narrative, assign the time to a matter, and submit — all in under 30 seconds. Time entries sync to the billing queue instantly and post to QuickBooks Online automatically when invoiced.
How much billable time do law firms lose without proper time tracking?
Studies show law firms lose up to 40% of billable time through leakage — time worked but never recorded. LeanLaw firms recover an average of $61,000 in leaked revenue per attorney each year by capturing every billable minute at the moment it happens.
Can attorneys track time on mobile devices?
Yes. LeanLaw's mobile-ready interface lets attorneys start timers, log expenses, and submit time entries from any smartphone or tablet — so billable time gets captured in court, on calls, and between meetings, not reconstructed from memory at the end of the week.
How does LeanLaw handle expense tracking for law firms?
LeanLaw lets attorneys and staff log client expenses directly to matters — court costs, filing fees, travel, expert witnesses, and any other disbursement. Expenses flow into the billing queue and appear on client invoices automatically. Every expense syncs to QuickBooks Online in real time.
Does LeanLaw integrate time tracking with billing?
Yes. Time and expense entries in LeanLaw feed directly into the billing queue. Billing administrators can review WIP, approve entries, and generate invoices in batch — all without re-entering data. The entire workflow from first timer tap to collected payment lives in one connected system.
Can LeanLaw track time for flat-fee and contingency matters?
Yes. LeanLaw supports all billing models. For flat-fee matters, time is tracked against the matter budget so you can see your true margin — even if the time never appears on the invoice. For contingency cases, time and expense tracking feeds cost-recovery and settlement worksheets.
What reports does LeanLaw provide for time and expense data?
LeanLaw generates WIP reports by attorney, matter, and practice area; realization rate and effective hourly rate reports; billable vs. non-billable hour breakdowns; time-entry compliance reports; and expense recovery summaries — all updated in real time from QuickBooks Online.
Does LeanLaw have a document management system?
No. LeanLaw is an accounting-focused legal billing platform, not a document management system. It is designed to handle the financial operations of a law firm — time tracking, billing, trust accounting, and collections — with deep QuickBooks Online integration. For document management, LeanLaw integrates with best-in-class DMS providers such as NetDocuments, so firms can pair purpose-built tools rather than compromising on either.
Does LeanLaw integrate with Microsoft Office 365 calendars?
Yes. LeanLaw connects to Microsoft Office 365 calendars (as well as Google Calendar) so attorneys can review their calendar events and convert meetings, calls, and hearings into billable time entries directly from a calendar view. This closes the gap between time worked and time captured without requiring attorneys to reconstruct their day from memory.
