The field tech job app

Tap through a real service call: pick the job, work the checklist, snap photos, capture model and serial, add parts, and get a signature — all of it happily offline until the truck finds signal.

Why techs actually use it

  • • Big targets — everything works with gloves on.
  • • Data plate scan instead of typing a serial in an attic.
  • • Photos attach to the ticket, not to a group text.
  • • Signature closes the call; the office gets the invoice.

Truck log

  • · Route synced to truck 3 before leaving the shop.

Yours would follow your checklist, your parts list, your paperwork.
