The Wrong Tool for Ontario Solo and Small Firms
Built for a different world
Aderant Expert is purpose-built for AmLaw 100 and 200 firms — large practices with dedicated IT departments, implementation teams, and finance professionals. Ontario solo and small firm lawyers don't need enterprise financial management for hundreds of lawyers; they need a platform that handles trust accounting, billing, and matter management simply and compliantly.
Enterprise cost without enterprise need
Aderant requires six-figure annual contracts, months of implementation, and ongoing IT resources. For a solo practitioner or two-lawyer firm, this is entirely impractical. Atticus provides all the core practice management functionality Ontario lawyers need at $149 CAD/month with zero implementation time.
Ontario-specific compliance built in
Aderant was not designed for Ontario LSO compliance. Adapting it to meet By-Law 9 trust accounting requirements requires custom configuration. Atticus is built specifically for Ontario law firms — LSO trust accounting, HST billing, and Limitations Act deadline tracking are built in from day one, no customization required.
Enterprise Power, Solo Firm Simplicity
Atticus gives Ontario solo and small firm lawyers the practice management, trust accounting, and AI intelligence they need — without the enterprise complexity or cost.
