Overview
CosmoLex is a law practice management platform that uniquely bundles complete legal accounting — trust accounting, IOLTA compliance, accounts receivable, accounts payable, and a full general ledger — directly into the platform subscription. Most legal practice management tools require a separate QuickBooks subscription for full accounting functionality; CosmoLex eliminates that requirement entirely. For law firms that find the Clio-QuickBooks integration complex or prefer a single-vendor accounting solution, CosmoLex is the natural alternative. Trust accounting is fully integrated with billing and AR, enabling three-way reconciliation, client ledger management, and bar-compliant record-keeping from the same interface attorneys use to manage matters and send invoices. Beyond accounting, CosmoLex covers matter management, time and expense tracking, legal invoicing, document storage, and a client communication portal. LEDES billing is available for firms serving corporate clients under e-billing requirements. The platform includes built-in business reporting: profitability by matter, billing realization rates, collection performance, and trust account activity — without requiring a separate reporting tool or QuickBooks accountant to generate them. CosmoLex is cloud-based with no server hardware required. Pricing is $89/user/month, with a 10-day free trial available. Best for solo practitioners and small to mid-size firms that want a single system for practice management and financial management, without the complexity of maintaining multiple integrated applications.
Key features
Built-in Business Accounting
Full double-entry accounting with P&L statements, balance sheets, accounts payable/receivable, and general ledger. Not a QuickBooks-lite — a complete accounting system embedded in the practice management platform. Eliminates the need for external accounting software.
Integrated Trust Accounting
IOLTA trust ledgers and business accounting share the same general ledger, eliminating the reconciliation overhead between two systems. Includes three-way reconciliation and state bar compliance reports.
Time Tracking and Billing
Timer-based and manual time entry with flat-fee, hourly, and contingency billing. Batch billing, invoice customization, and credit card processing via LawPay integration.
Matter Management
Matter lifecycle management with client records, tasks, deadlines, and document storage organized by matter.
Document Management
Secure file storage with matter organization, version history, and document sharing via integrations with Box and Dropbox.
Combined Financial Reporting
Profit-per-matter, billing realization, origination credit, and full financial statements in a single reporting environment — no exporting to Excel or third-party BI tool required.
