Legal billing software for law firms using QuickBooks Online

Visit LeanLaw

LeanLaw is legal billing software for law firms using QuickBooks Online, connecting time and expense entries, invoice review, payments, client trust records, and reporting in a single financial workflow. It supports hourly, flat-fee, and contingency billing models and works alongside existing case and document tools, with an active QuickBooks Online subscription required.

Features include time and expense tracking across desktop, mobile, and timer; billing and invoicing with WIP review, bulk rate edits, LEDES formatting, split billing, and client-portal delivery; e-payments with ACH and credit-card acceptance; trust accounting with three-way reconciliation and automated trust-to-operating transfers; and reporting covering realization, AR aging, collections, matter profitability, and partner compensation. ClerkAI, a read-only assistant, answers billing and revenue questions in plain language. Integrations include QuickBooks Online, Clio, MyCase, and NetDocuments, with a public API and an MCP layer in private beta.

LeanLaw is intended for law firms and their attorneys, billing teams, and bookkeepers. It is packaged as a 14-day free trial with no credit card required, followed by seat-based plans: Core, Pro, Elite, and Contingency, with Elite and Contingency priced on a custom basis. QuickBooks Online is a separate subscription, and QuickStart onboarding for migration and training begins with a paid subscription.
