Paul runs a 2-truck garage door service business in suburban Houston. Here is how a day that starts with an emergency broken spring and ends with a new-door install quote moves through Bit & Grain.
A homeowner calls with a broken torsion spring: the door is stuck down and they can't get the car out. Paul creates a new job in Bit & Grain, adds the address to the morning route, and drives over. He identifies the spring specs (2-inch wire, 25-inch length, right-wound), pulls a matching spring from the truck, and replaces it. He logs the job in Bit & Grain: spring replaced, cable inspected and OK, safety reverse tested. He sends the invoice via Stripe. The homeowner pays before the spring is packed away.
While Paul is replacing the spring, the homeowner mentions the opener is also making grinding sounds. Paul diagnoses a failing drive gear and recommends replacing the opener. He creates a change order in Bit & Grain: one belt-drive opener at the truck stock price, plus 30 minutes install labor. The homeowner approves it from their phone. Paul installs the opener and the change order rolls into the same invoice as the spring repair.
After the call, Paul notes the spring and opener used from the truck in Bit & Grain's Equipment Tracking. He stops at the spring distributor to restock and snaps the receipt in Grain AI chat. The parts cost assigns to the truck inventory automatically. He knows exactly what is on each truck before the next call.
Paul's second call is a quote for a new 16x7 insulated steel door with a smart-home opener. He measures the opening, photographs the existing door, and builds the estimate in Bit & Grain: door panels, opener, springs, cables, track, and labor. He emails the estimate link from the driveway. The homeowner approves it that evening and pays a 50% deposit via Stripe. The install is scheduled in Bit & Grain for next Thursday.
