Supermarket Mobile Self-Checkout App Development
Budget: $5,000 – $10,000 USD
? Build a Supermarket Self-Checkout Mobile App (POS + Scan & Pay)
Description
We are looking for an experienced mobile app development team or freelancer to create a self-checkout mobile application for supermarkets and grocery stores. The app must allow customers to scan products using their phone camera, add them to a cart, and complete the payment digitally—eliminating the need for traditional checkout queues.
The system should also sync with the store’s inventory in real time, ensuring accurate stock updates and pricing. The goal is to improve customer experience and reduce checkout time with an easy-to-use, mobile-first solution.

4️⃣ Real-Time Inventory Sync – Stock updates automatically after purchase.
5️⃣ Discounts & Offers – Apply store discounts and loyalty points.
6️⃣ E-Receipts – Users get digital receipts instead of paper.
7️⃣ Store Management Dashboard – Admin panel for store owners to manage stock, pricing, and sales reports.
? Technology Stack (Preferred)
? Mobile App:
✅ Flutter (Preferred) or React Native – Cross-platform for iOS & Android.
✅ Google ML Kit / OpenCV / Scandit – For barcode & QR scanning.
