The problem

Technicians got jobs by phone and wrote reports on paper. Details were lost and invoices went out days late.

What we built

  • Each technician sees today's jobs, addresses and customer notes.
  • Photos, parts used and the customer's signature are saved on the job, even offline.
  • Data syncs when signal returns, and the office sees live status.
