What Is Tabs3?
Tabs3 (and its companion product PracticeMaster) is a Windows desktop legal billing and practice management system published by Software Technology LLC. It has been in use since the 1980s and is still used by some US and Canadian law firms that built their operations around the platform decades ago.
Tabs3 offers time tracking, billing, and trust accounting in a desktop environment. PracticeMaster adds matter management, calendaring, and document management. The products have been updated over time but remain fundamentally desktop-architecture software — they require Windows installation, local or server-hosted databases, and IT infrastructure.
Ontario lawyers still on Tabs3 typically face three common pain points: no cloud access (can't work from home without a VPN or hosted solution), US-configured trust accounting that doesn't match LSO By-Law 9 rules, and a dated interface that requires significant training for new staff.
Why Ontario Lawyers Move from Tabs3 to Atticus
Cloud-Native — No VPN, No Server, No IT
Atticus runs entirely in the browser — accessible from your office computer, home laptop, or iPad without VPN or remote desktop. Tabs3 requires either a local Windows installation or an expensive hosted solution with VPN access. For Ontario firms working in hybrid or remote environments, Atticus eliminates the IT overhead entirely.
LSO By-Law 9 Trust Accounting — Native
Atticus implements the complete LSO By-Law 9 trust accounting framework from day one: client trust ledgers, general trust account, trust-to-general transfers, monthly reconciliation workflow, LAWPRO pooled trust interest, and the annual trust report. Tabs3's trust accounting module follows US trust rules — it requires manual configuration to approximate LSO By-Law 9 compliance, and there is no guarantee that the configuration meets LSO standards.
AI Document Intelligence — Not Just Storage
Atticus uses AI to analyze Ontario legal documents — extracting key facts, parties, dates, and obligations from contracts, corporate documents, real estate files, and court materials. Tabs3/PracticeMaster manages documents as files with folder structures; there is no AI document analysis capability.
Simple Pricing in CAD
Atticus is $149 CAD/month for the whole firm. Tabs3 + PracticeMaster pricing starts at approximately $80–$120 USD per user per month for the combined suite, plus server costs, IT maintenance, and annual support contracts — typically $150–$350+ CAD per user per month fully loaded. For a two-lawyer firm, the annual savings switching to Atticus can exceed $5,000.
