What the pricing really means
Both Assembly Neos and PerfectLaw 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

Where Assembly Neos falls short

- Fewer reviews and smaller user base than CASEpeer or Filevine
- The Neos brand (formerly known as LawRuler for CRM) can be confusing
Where PerfectLaw falls short
