Service history for each car, including work you passed on so it comes up again.

What it does

  • Keeps each car's mileage and next service due, so customers know when to come back.
  • Books a drop-off with posted prices and a note for the tech.
  • Shows where the car is in the shop, and flags the moment the shop needs an answer.
  • Puts the inspection in plain view, red, yellow and green, with a price and an approve button on each item.

Built to stay small

Five screens around the two things customers do every visit: drop the car off and say yes or no to the work. Payment, invoices and parts stay in the shop's POS and shop management software; approving a job never charges a card in the app.

It would ship to iOS and Android.
