Overview
Tabs3 is one of the most established legal billing and financial management suites in the industry, with a track record stretching back to 1979. The Tabs3 platform includes three integrated modules: Tabs3 Billing for time tracking and invoicing, PracticeMaster for practice management and calendaring, and Tabs3 Financials for general ledger, accounts payable, and trust accounting. Law firms that have used Tabs3 for decades stay for its reliability, depth of reporting, and the trust accounting module's strict IOLTA compliance safeguards. While the platform has a steeper learning curve than newer cloud-native tools, Tabs3 Connect provides browser-based access for remote work. Tabs3 is particularly popular with mid-size regional firms that need granular financial controls. Tabs3 Connect provides browser-based access to Billing and PracticeMaster from any device, addressing remote access needs without requiring full platform replacement. Tabs3 integrates with Microsoft Outlook for email and calendar synchronization, and with LawPay for online invoice payment. The platform's data conversion tools support migration from other billing systems. Pricing is based on the number of timekeepers; firm software licenses are available for outright purchase rather than subscription, which many long-tenured firms prefer for budget predictability. A hosted Tabs3 option is available through authorized resellers.
