What the pricing really means
At first glance, RunSensible 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 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 RunSensible wins
- Built-in VoIP phone system and texting means all client communications are logged automatically to matters
- Competitive pricing starting at $49/user for CRM with phone integration
- 14-day free trial to test the phone system with real calls
- CRM pipeline for intake is well-designed for tracking leads through conversion
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 RunSensible falls short
- Very few reviews (30 total across platforms) — the product is relatively new with a small user base
- No conflict checks or court rule deadlines
- Full practice management requires the $89 plan; trust accounting requires $149
- Smaller company means uncertain long-term viability compared to established players
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.
RunSensible
Target: 1-20 attorneys
RunSensible is interesting if your firm's biggest pain is scattered phone communications. The built-in VoIP is genuinely useful. But the small user base and missing features mean you're taking a risk on a newer product.
