LeanLaw
Legal billing software built on QuickBooks.
About LeanLaw
LeanLaw runs inside QuickBooks Online rather than alongside it. Attorneys log time against specific matters, the data posts directly to QBO, and trust account transactions hit IOLTA-compliant ledgers without any manual journal entry. For a five-attorney firm already running payroll and vendor payments in QuickBooks, this means one set of books instead of two. The tool fits small to mid-size law firms — roughly two to thirty timekeepers — that bill hourly or on retainer and need LEDES 1998B format for corporate clients or insurance work. Matter-based time tracking, client trust ledgers, and three-way trust reconciliation cover the daily billing workflow without requiring staff to learn a separate platform. Where LeanLaw shows its limits: firms that have left QuickBooks for Sage or NetSuite get nothing here. The integration ecosystem is thin — QuickBooks and not much else — so any firm running a separate CRM or document management system will handle those connections manually. There is no free trial, which makes evaluation harder than it should be for a $55/month commitment.

Law firms using QuickBooks wanting to add legal-specific billing and trust accounting
Key Features

- IOLTA trust accounting compliance
- LEDES billing format support
- Legal matter time tracking
- Trust fund management
Pros & Cons
Pros
- Time entries post directly to QuickBooks Online general ledger with no manual export or reconciliation step
- Three-way trust reconciliation built in, covering the IOLTA compliance requirement that generic accounting software ignores
- Generates LEDES 1998B files for corporate and insurance billing without a third-party converter
- Matter-based reporting shows profitability per client or case inside the QBO reporting environment
- Trust fund requests and disbursements are tracked at the matter level, reducing the risk of commingling errors
- Works for firms already trained on QuickBooks, cutting onboarding time compared to a full platform switch
Cons
- No free trial — a firm must pay before it can evaluate whether the QuickBooks sync behaves correctly with its existing chart of accounts
- Only integrates with QuickBooks Online; firms on QuickBooks Desktop, Sage, or Xero have no path in
- Thin integration ecosystem means no native connection to Clio, NetDocuments, or common legal CRMs — those data handoffs stay manual
- Smaller user community than Clio or MyCase makes it harder to find peer advice or third-party consultants who know the product
- Reporting depth is constrained by QuickBooks Online's own limitations, which frustrates firms that need custom profitability or billing realization analysis
Ledger Brief Take
A QuickBooks-native solution that finally gives small law firms proper trust accounting and LEDES billing without abandoning their existing books. Rather than forcing firms into yet another platform, LeanLaw layers legal-specific functionality directly into QuickBooks, making it particularly compelling for practices already invested in the Intuit ecosystem but needing IOLTA compliance and matter-based billing.
Frequently Asked Questions
Common questions accountants ask about LeanLaw.
What does the $55/month entry price actually include?
The base plan covers core time tracking and billing for a small number of users, but seat-based pricing means costs rise as you add timekeepers. IOLTA trust accounting and LEDES billing are included across plans, not reserved for higher tiers. Check the current plan page before assuming the entry price covers your full headcount.
Does LeanLaw work with QuickBooks Desktop or only QuickBooks Online?
QuickBooks Online only. Firms still running QuickBooks Desktop would need to migrate to QBO before LeanLaw becomes an option. There is no integration path for Desktop, Sage, Xero, or any other accounting platform.
How does LeanLaw compare to Clio for a small law firm?
Clio is a full practice management platform that includes its own accounting layer, document management, and a large integration marketplace. LeanLaw does less but keeps QuickBooks as the single source of financial truth. Firms that want one platform choose Clio. Firms already committed to QuickBooks and wanting proper trust accounting without a full migration choose LeanLaw.
Is LeanLaw's trust accounting actually IOLTA compliant?
LeanLaw provides three-way trust reconciliation and matter-level trust ledgers, which are the core recordkeeping requirements for IOLTA compliance in most US states. It does not provide legal advice on compliance, and bar requirements vary by state. Confirm your state's specific rules with your bar association before relying solely on any software for compliance.
Can LeanLaw generate LEDES billing files for corporate clients?
Yes. LeanLaw exports LEDES 1998B format, which is what most corporate legal departments and insurance carriers require. Firms billing under alternative fee arrangements or flat fees should verify whether their specific billing guidelines require a format beyond 1998B before committing to the tool.
Is there a free trial or evaluation period?
No free trial is currently offered. Evaluation means paying from day one, which is a legitimate complaint for a product at this price point. Request a live demo from the vendor to walk through the QuickBooks sync with your actual account structure before committing.
