Clio Manage is one of the most popular legal practice management platforms — but it was built for global law firms. Atticus is built specifically for Ontario: native LSO trust accounting, deeper AI, and flat pricing for the whole firm.
Start Free TrialClio Manage is the core practice management product from Clio (Themis Solutions Inc.), a Vancouver-based company that has become the largest legal technology company in Canada. Clio Manage provides matter management, time tracking, billing, document management, and client portals to law firms worldwide.
Clio is strong on practice management fundamentals — its matter management and billing workflows are polished and well-designed. However, Clio was built for global law firms of all sizes, not specifically for Ontario's regulatory environment. Trust accounting for LSO By-Law 9 compliance requires additional setup with Clio Payments or third-party integrations — it is not a native out-of-the-box feature the way it is in Atticus.
For Ontario solo and small firms, the primary concerns with Clio are cost (per-user pricing that scales steeply) and the absence of deeply integrated LSO trust accounting. Atticus addresses both: native trust accounting, deeper AI purpose-built for practice files, and $149 CAD/month flat per lawyer per month.

Clio requires additional configuration or Clio Payments to handle Ontario trust accounting. Atticus was built with LSO By-Law 9 trust accounting as the foundation — receipt, disbursement, reconciliation, and audit trail from day one.
Atticus processes every uploaded document automatically — extracting parties, dates, dollar amounts, and deadlines without any manual input. Clio Duo is a general AI assistant, not a document intelligence layer built around your matter files.
Clio charges $89–$149+ USD per user per month — a 3-lawyer firm pays $267–$447+ USD/month (before exchange rate) just for Manage, before any Clio Payments add-on. Atticus is $149 CAD/month per lawyer per month.
Atticus tracks every deadline across all matters and sends overdue alerts automatically. Ontario limitation periods, discovery deadlines, LTB hearing dates — all tracked without manual setup. Clio uses manual task management.
Clio serves law firms globally — features and workflows are built for the lowest common denominator across many jurisdictions. Atticus is built solely for Ontario practice, with LSO compliance, Ontario-specific AI context, and Ontario legal terminology throughout.
