Apperio is a UK-founded real-time legal spend analytics platform for corporate in-house legal departments. Atticus is built from the ground up for Ontario law firms — LSO-compliant trust accounting, Canadian AI, and full practice management at $149 CAD per lawyer per month.
Apperio is designed for corporate in-house departments monitoring law firm spend in real time. Atticus is a complete Ontario law firm platform — practice management, trust accounting, and Canadian AI built for the lawyers generating the work.
Apperio provides real-time legal spend analytics for in-house legal departments monitoring outside counsel bills. Atticus is built for Ontario law firms — the lawyers doing the work, billing the clients, and managing trust accounts, not the departments receiving their invoices.
Atticus includes trust accounting built specifically for Ontario LSO By-Law 9 compliance. Apperio has no trust accounting functionality — it tracks spend from an in-house perspective, not law firm trust fund management.
Apperio does not include practice management, client intake, conflict checking, billing, or AI document analysis for law firm work. Atticus delivers all of these in a single platform at $149 CAD per lawyer per month.
Atticus AI is trained on Canadian and Ontario legal context. Apperio provides spend analytics — not AI-powered legal work product analysis, document review, or Ontario limitation period intelligence.
Atticus AI extracts key dates from your client documents and applies Ontario Limitations Act 2002 rules automatically. Apperio has no limitation period tracking — it is a spend visibility tool for corporate clients.
Atticus is $149 CAD per lawyer per month for complete Ontario practice management including AI. Apperio is an enterprise spend analytics tool for large corporations — not designed for Ontario solo and small law firms.
