ChanMeng666/Automotive-Repair-Management-System ? reverse-engineered prompt

Build me a polished web app for an automotive repair shop management system that feels ready for real businesses.

It should let a shop owner manage customers, repair jobs, parts inventory, invoices, and team members from one place. I want separate experiences for administrators and technicians, with role based access so each person only sees what they need. The app should support multiple repair shops using the same system, but keep each shop’s data fully separated. Include a simple onboarding flow for new shops, sign in with Google if possible, and a subscription billing flow for paid plans.

Make the UI modern and responsive, with a clean industrial look, dashboards, charts, and a good mobile experience. Use the existing Flask and database setup in the repo, and if you need anything current from the docs or services, look it up online first. Also make sure the app is easy to deploy and comes with sensible test coverage and a solid default admin experience.
