Asynchronous photo/video/error code sharing with remote experts
Push-to-message when online; auto-sync when offline
Integrated ticketing and status tracking for support requests

Target Users: HVAC field technicians servicing commercial VRF systems who frequently work in areas with poor cellular coverage

Revenue Model: SaaS subscription starting at $29/month per technician (annual plan) with a free tier limited to 5 cached manuals and 10 async messages/month
