What the pricing really means
Rocket Matter publishes their pricing upfront, which is a good sign. Assembly Neos 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 Assembly Neos wins
- Purpose-built for plaintiff firms with medical provider tracking, lien management, and settlement disbursement sheets
- Intake module captures leads from web forms, phone calls, and referral sources with attribution tracking
- Workflow automation can move cases through stages automatically based on triggers and deadlines
- Integrates with medical record retrieval services
Where Rocket Matter wins
- LEDES billing support out of the box, which is essential if you bill corporate clients or insurance companies that require it
- 15-day free trial is one of the longest in the category
- Billing reports are detailed enough to spot underperforming attorneys or matters that are bleeding money
- Now owned by the same company as CosmoLex, so integrations between the two are tight if you need advanced accounting
Where Assembly Neos falls short
- No public pricing — custom quotes suggest mid-market pricing
- Only useful for plaintiff-side litigation — defense firms and transactional practices need to look elsewhere
- Fewer reviews and smaller user base than CASEpeer or Filevine
- The Neos brand (formerly known as LawRuler for CRM) can be confusing
Where Rocket Matter falls short
- No built-in intake forms or eSignature — you'll need separate tools for client onboarding
- No court rule deadline calendaring
- Interface feels dated compared to newer tools like Clio or PracticePanther
- At $65/user it's not the cheapest option, and the Premier plan at $95 is needed for document automation
