What the pricing really means
Both Assembly Neos and Centerbase use custom pricing, which means you need to talk to sales. In our experience, custom pricing usually means the product is targeting larger operations and the monthly cost will be higher than products with published prices. Ask specifically about total year-one cost, including setup, onboarding, and training.
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 Centerbase wins
- Financial reporting and profitability analysis is deeper than most competitors, with partner compensation tracking
- LEDES billing built in with proper compliance for corporate and insurance clients
- Multi-office and multi-entity support for firms with multiple locations
- Custom pricing means you negotiate based on firm size, which can work in your favor
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 Centerbase falls short
- No public pricing — you have to go through sales, and mid-market typically means $100-200/user/month
- G2 rating of 4.0 suggests the user experience has room for improvement
- Fewer reviews (80 total) than major competitors means less community knowledge base
- Probably overkill for firms under 10 attorneys
