What the pricing really means
At first glance, Clio looks cheaper at $49/month vs $89/month. But sticker price is only part of the story. Look at what is included on the base plan, how many users you get, and whether you need add-ons to get the features you actually need. The $99/month plan that requires $200 in add-ons is actually more expensive than the $250/month plan that includes everything.
Where Clio wins
- Largest user base in legal tech, which means 250+ integrations, active community forums, and no shortage of YouTube walkthroughs
- Clio Grow (intake and CRM) bundles into the Complete plan, so you get lead tracking without bolting on another tool
- Mobile app actually works for time tracking between court appearances and client meetings
- 7-day free trial with no credit card, plus they offer data migration assistance from competing products
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 Clio falls short
- Pricing adds up fast at $149/user/month for the Complete plan — a 5-attorney firm pays $745/month before any add-ons
- Trust accounting is solid but not as deep as CosmoLex, which was purpose-built for legal accounting
- Court rule calendaring requires the Advanced plan at $119/user — not available on the cheaper tiers
- Some users report the reporting tools lag behind what you'd get from a dedicated BI tool
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
Who is each product built for?
Clio
Target: 1-100+ attorneys
Clio is the safe pick for most law firms. It covers everything, integrates with everything, and has the largest support ecosystem. Skip it if you're a solo attorney watching every dollar — $49/month per user for EasyStart is reasonable, but you'll want Advanced ($119) to get the features that actually matter.
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.
