Bilingual Inventory POS App

For small retail operation and need a straightforward mobile solution that lets me manage stock, record sales and see profit in real time. The app has to work on both iOS and Android and must allow users to switch instantly between Bangla and English.

Core workflow
• A staff member snaps a product photo or simply points the camera at its barcode; the app recognises the item, pulls up its card, and lets the user adjust quantity.
*From picture app can read each word and copy to system so user can update system if in case barcode not available.
• Stock levels update in the cloud so every device stays in sync.
• Each sale produces a printable / shareable receipt and the transaction is appended to a running Excel workbook stored online (Google Drive, OneDrive or a similar platform—whichever you recommend).
• A dashboard shows current inventory, total revenue, cost of goods sold and net profit so I always know where I stand.

I am open to React Native, Flutter or any other cross-platform framework as long as performance is smooth on low-end phones. Barcode and image recognition can rely on open-source libraries or paid APIs—accuracy is more important than cost in this case.

Deliverables
1. Universal mobile app (iOS + Android) with Bangla / English toggle
2. Cloud-based back-end, database and Excel-sync service
3. Source code with brief setup docs
4. One remote hand-over session to get the app live on both stores and linked to my chosen cloud drive

Acceptance criteria
• Barcode scan and photo recognition both add or deduct stock without manual typing.
• Switching languages never requires a restart.
* App can connect local ptinter and print the record.
*Create invoice if customer required.
• Receipts generate in under three seconds and save to the Excel ledger automatically.
• Inventory, revenue and profit figures match a provided test dataset.
