I need a mobile application that lets an auto-parts dealership handle every step of an order on both iOS and Android. The app’s single goal is to simplify order management—for my staff behind the counter and for customers on the go—so everything from stock availability to package delivery is visible in one place. Core functionality must include: • Order tracking in real time, with status updates pushed to customers and mirrored in an admin view. • Live inventory management that syncs with my existing catalog so out-of-stock items never appear as available. • Seamless, secure payment processing that accepts the major card networks and logs each transaction against the associated order. A lightweight admin panel (web or in-app) should let me adjust quantities, update order states, and generate basic reports without extra plugins. Clean UI, fast load times, and straightforward navigation are essential because most users will be mechanics scrolling quickly on their phones while in the shop. Please deliver: 1. Production-ready iOS and Android builds plus source code. 2. Setup instructions and brief documentation on how to connect the app to my current inventory database. 3. Deployment support through App Store and Google Play review. Once installed, the app should show live inventory, allow checkout with payment, and push a shipping confirmation that tracks through to delivery; only then will the project be considered complete.
