CosmoLex vs Legal Files
CosmoLex scores 8.0/10 vs 6.2/10. Best for: Solo and small firms that want accounting, billing, and trust compliance in one platform so they can ditch QuickBooks entirely.
CosmoLex scores higher overall at 8.0/10 vs 6.2/10. CosmoLex is the best choice if you're tired of reconciling between your practice management tool and QuickBooks. The built-in accounting is genuinely complete, not a half-baked add-on. Skip it if you already have an accountant who handles your books and you just need case management.

What the pricing really means
CosmoLex publishes their pricing upfront, which is a good sign. Legal Files requires you to contact sales for a quote. When a company hides pricing, it usually means the cost is high enough that they want a salesperson to justify it before you see the number. Always ask for total year-one cost, not just the monthly subscription.
Where CosmoLex wins
- Only legal PM tool with full built-in accounting that genuinely replaces QuickBooks — not just a sync, actual double-entry bookkeeping
- Trust accounting and IOLTA compliance is the deepest in the market, with three-way reconciliation built in
- One subscription covers practice management + accounting + billing, which saves $50-100/month vs separate tools
- 10-day free trial to test whether the accounting features actually fit your workflow
Where Legal Files wins
- Purpose-built for in-house legal departments with matter management, spend tracking, and outside counsel management
- Litigation hold and legal hold management for e-discovery compliance
- Contract lifecycle management included
- Trusted by government agencies and universities
Where CosmoLex falls short
- At $89/user as the only price tier, there's no cheaper entry point for firms that just want basic case management
- Interface is functional but not as polished as Clio or PracticePanther
- No court rule deadline calendaring built in
- CRM features require the $109/user plan, which pushes the price above most competitors
Where Legal Files falls short
- No billing or trust accounting — this is for in-house teams, not billable-hour firms
- No public pricing and enterprise sales process
- No client portal, mobile app, or eSignature
- Very limited reviews make it hard to assess independently
Who is each product built for?
CosmoLex
Target: 1-15 attorneys
CosmoLex is the best choice if you're tired of reconciling between your practice management tool and QuickBooks. The built-in accounting is genuinely complete, not a half-baked add-on. Skip it if you already have an accountant who handles your books and you just need case management.
Legal Files
Target: 10-500+ users
Legal Files serves a different market than most legal PM tools — in-house legal departments, not law firms. If you're corporate counsel managing outside legal spend and litigation holds, it's worth a demo. Law firms should look elsewhere.
