Hardware Store Android Ordering App

I’m gearing up to launch a brand-new Android app that lets my hardware-shop customers browse products, add items to a cart, and place orders straight from their phones. The focus is strictly on online sales and ordering—no inventory management module for now—so every screen should guide shoppers smoothly from discovery to secure checkout.

Core flow I need:
• Product catalogue with categories, search, photos, prices and live stock count pulled from our existing SQL database (REST/JSON endpoint is ready).
• Cart, quantity edits and promo-code field.
• Checkout supporting cash-on-delivery plus at least one standard payment gateway (Stripe or Razorpay is fine).
• Order confirmation, push notification updates and a simple order-history screen.
• Lightweight admin panel or API hook that pings our in-store POS the moment a new order lands.

Tech is up to you as long as it’s native Android (Kotlin or Java in Android Studio) and plays nicely with our API; Firebase for push and analytics is ok. I’ll supply logos, color palette and product data.

Timeline is tight: I’d like a clickable prototype within the first week and a publish-ready APK on Google Play ASAP after that, including one round of revisions based on store feedback.

Deliverables will be:
1. Full Android Studio project with clean, well-commented code.
2. Signed release APK/AAB ready for Play Store submission.
3. Brief hand-off document outlining build steps, API endpoints used and how to update product data.

If this sounds doable on your schedule, let’s talk and get it into customers’ hands fast.
