The gap between what your firm earns and what it collects lives in the handoffs — billing that doesn't sync to accounting, reporting that arrives after month-end, and manual work holding together systems that were never built to talk to each other.
LeanLaw is built around the full workflow, because closing that gap requires owning every stage of it: intake, time capture, billing, collections, and the reporting that should be driving all of it.
Turn every billable moment into collected revenue
The revenue lifecycle breaks in four places — intake, time capture, billing, and collections. Here's what LeanLaw does at each one.
Time & Expense Tracking
Every hour your attorneys work is revenue the firm can collect — when it's captured accurately, completely, and close to when the work happens. Time capture runs across desktop, mobile, and timer, so billable work gets recorded in the moment, before the detail goes cold.
What it delivers
Higher utilization, fewer write-offs, and a billing cycle that starts with data your billing administrator can trust.
Billing & Invoicing
Invoices that leave the firm complete, accurate, and on schedule shorten the collection cycle before it starts. WIP review, bulk rate edits, LEDES formatting, split billing, and client-portal delivery — so every invoice that goes out is the right invoice, and none come back.
What it delivers
Fewer billing disputes, faster invoice-to-payment cycles, and a workflow that runs on system discipline, not individual follow-up.
E-Payments
Full-balance payment links, ACH, and credit-card acceptance — all reconciled directly to QuickBooks Online the moment payment lands. Pay-from-trust workflows for IOLTA clients. The client gets a clear payment path; the firm gets accurate books, automatically.
What it delivers
Shorter days-to-collect, higher collection rates, and trust accounting that stays current without the manual work.
See your financial data in real time
A slow collections month is recoverable in week one. By week four, the damage is done. LeanLaw surfaces realization, AR aging, and collection performance in real time — so operators have room to act, not just report.
Lean Insights Advanced Reporting
Realization, collection rate, days-to-collect, and lockup exposure — visible in real time across every matter and every timekeeper. Reporting runs on live ledger data, current to the billing day, so the numbers reflect what is actually happening when the question comes up.
What it delivers
Partner-compensation decisions grounded in actual performance. Collections strategy that starts in week one, not week four.
ClerkAI
Firm revenue data contains the answers to most billing questions your team asks. ClerkAI makes those answers accessible in plain language, directly in the app — time entries, WIP, invoices, collections — across the full billing lifecycle. Ask the question when it comes up; get the answer in real time.
What it delivers
Immediate visibility into billing and revenue performance for the people who need it — from the managing partner before a Friday call to the administrator checking WIP aging before month-end.
Reports & Compensation Tracking
Origination splits, timekeeper performance, and matter profitability — all drawn from the same live data your billing runs on. Billing and accounting agree by design, so the reports reflect what the books confirm.
What it delivers
Distributions that are deliberate, not estimated. Partner conversations that start with numbers, not assumptions.
Matter Management
Every open matter is a revenue event in progress. LeanLaw gives you the full financial picture of each one — what's been billed, what's been collected, and what's still sitting in WIP — accessible from anywhere, in real time.
What it delivers
Matter-profitability visibility before matters close — so you can see which matters drive firm revenue and which erode it while there is still time to act.
Connect every system. Control the full picture.
Connected workflows are how firms stop losing revenue to the gaps between systems. LeanLaw ties billing, payments, accounting, and reporting together at the data level — one revenue experience across the tools your firm already relies on.
QuickBooks Online Integration
LeanLaw requires QuickBooks Online — the financial source of truth the entire platform is built around, so billing, collections, trust accounting, and reporting all operate from the same live data. Real-time sync eliminates duplicate entry and manual exports; every dollar that moves through LeanLaw moves through QuickBooks.
What it delivers
Financial data that is always current, always trustworthy, and built to stay that way.
Trust Accounting
IOLTA compliance is the foundation every payment workflow should be built around — and in LeanLaw, it is. Three-way reconciliation, automated trust-to-operating transfers, sub-ledger management, and audit-ready reporting are built into the core platform.
What it delivers
Compliance overhead that runs at the system level, so audits stay clean regardless of individual behavior.
Integrations
LeanLaw connects to the platforms your firm already uses — document management, practice management, and legal-specific workflows — so the work your attorneys do in one system flows into LeanLaw billing and accounting without re-entry.
What it delivers
A revenue experience that stays connected across the full stack — no double entry between the tools your firm relies on.
Built for every billing model — and every margin risk that comes with it.
Every operating model creates its own place where revenue can leak. LeanLaw tracks time, revenue, and profitability across all three — so you can see which matters are worth taking and which are eroding the firm while they're still open.
Hourly
Every logged hour should become a collected dollar. See where realization leaks — before month-end.
ExploreFlat Fee
Fixed price doesn't mean fixed margin. Track matter profitability before scope creep compounds.
ExploreContingency
Outcome-based doesn't mean outcome-blind. Track case value, case costs, and cash exposure from case open to cash collected.
