LeanLaw review

LeanLaw takes a different approach from the all-in-one suites: it handles legal time, billing and trust work, and leaves the general ledger in QuickBooks Online. Every plan includes two-way QuickBooks Online sync, trust accounting with IOLTA compliance, e-payments and a reporting dashboard, so the firm's accountant keeps working in a familiar tool while attorneys bill in LeanLaw. Core at $55 per user per month covers time and expense tracking and professional invoices. Pro at $75 adds three custom invoice templates, LEDES files, precise user permissions and matter-based accounting. A custom-priced Contingency plan adds a settlement wizard, lien management, automated settlement statements and case profitability reporting, which is unusual in a billing tool. The catch is the dependency: you also pay for QuickBooks Online, and LeanLaw says a one-time onboarding fee may apply depending on plan and firm size. Firms without QuickBooks or that want document and calendar tools should look at CosmoLex or Clio.
