Cravab — AI Phone Receptionist & Operations PWA

Live Demo Available
Experience this system firsthand in our demo environment.
The Client
Cravab is published by Stoimera as public software for plumbing, HVAC, electrical, landscaping, cleaning, detailing, and similar call-driven service businesses.
The Challenge
Appointment-based field-service teams need always-on call coverage, structured booking, and operations tooling without vendor lock-in.
Teams out on jobs miss calls, CRM data lags, and ops visibility suffers when reception and dispatch depend on a single stack that cannot be audited, extended, or self-hosted.
Key Issues
- Missed calls and slow follow-up when staff are in the field
- Need for transparent, forkable infrastructure instead of black-box SaaS
- Mobile-first workflows for technicians, dispatchers, and managers
The Solution
Calls & booking
Inbound call flows, lead capture, and appointment booking aligned with real operations.
Operations core
Clients, services, appointments, and reporting in one installable PWA.
Secure multi-tenancy
Postgres and Supabase Row Level Security for tenant-safe data boundaries.
