Here's what nobody tells you: Most AI receptionists are either:

  1. Locked to specific software (only work with ServiceTitan/HCP/Jobber)
  2. Phone-only solutions (miss web leads, texts, and online bookings)
  3. Require weeks of onboarding (white-glove setup, demos, contracts)
  4. Cost more with hidden fees ($500-2,000/month)

There's a better option: AutoRev.ai - the only cross-channel AI receptionist (phone + web + SMS + portal) built specifically for trade contractors that you can start using in 10 minutes for $399/month with no FSM lock-in.

AutoRev AI (1 year):

  • Built with 2024-2025 AI (GPT-4, Claude)
