S.R. Enterprises is a wholesale auto-parts business in Hisar, Haryana. I built its official catalogue app so customers, dealers, mechanics and workshops can find the right car or commercial-vehicle part in seconds instead of flipping through printed price lists. It ships on Android through Google Play and on Windows through the Microsoft Store.
What it does
- Explore parts by vehicle — cars, SUVs, trucks, buses and LCVs across 33 makes; pick yours and see only the parts that fit.
- 7,951 parts from 22 brands — ZIP, YSN, Roots, VAI and more, searchable by part number or name, with MRP and dealer prices.
- Price lists that work offline — every brand’s PDF catalogue, opened right inside the app.
- Saved parts and enquiries, plus push notifications for new offers.
- Dealers register and are approved before they see trade prices.
How it’s built
- One Flutter codebase for the dealer app on Android and Windows, plus a separate admin app.
- A hardened Fastify API on Node 22 with MongoDB Atlas, Firebase Auth and Cloud Messaging.
- A Next.js admin console that turns each brand’s Excel price list into catalogue parts, with roll-back.
- Images and catalogues served from a versioned global CDN; 64 automated API tests.
Find the right part, fast.
