What the pricing really means
Both INSZoom and ProLaw 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.
