Summary

LeanLaw provides law firms with timekeeping, billing, trust accounting, payments, and financial reporting connected to QuickBooks Online. It supports hourly, flat-fee, and contingency billing. Trust-accounting tools include three-way reconciliation, transfers from trust to operating accounts, sub-ledgers, and IOLTA reporting. The Core plan is 55.00 USD per month per user and includes time and expense tracking, e-payments, reporting, trust accounting, professional invoices, and two-way QuickBooks Online sync. Pro costs 75.00 USD per month per user and adds invoice templates, LEDES files, permissions, and matter-based accounting. Contingency and Elite pricing is custom. An active QuickBooks Online subscription is required; QuickBooks Desktop is not supported. LeanLaw's 14-day trial does not require a credit card, though migration and QuickStart onboarding start with a paid subscription. Its mobile app shows matter details but cannot create or edit matters. The public REST API supports access to clients, matters, time entries, expenses, invoices, users, and codes.
