Jewellery Management App Development -- 2

I need an all-in-one mobile (or web) application that keeps my jewellery business organised from the back room to the sales counter. The core goal is internal management—tracking every item of stock, every customer order and payment, and every supplier interaction—rather than public e-commerce or design tools.

The app should let my shop owner account and our sales staff log in and handle day-to-day tasks quickly. To make clear what has to be covered, here are the key functional areas I must see working end-to-end:

• Stock & product details: add new pieces, update weights, stones, karats and photographs, and see real-time inventory levels.
• Customer orders & payments: create orders, take part-payments, record full settlements, and link everything back to the product record.
• Suppliers, purchases & repairs: log supplier deliveries, purchase prices, send-out and return dates for repairs or polishing jobs.
• Barcode generation: print or display barcodes/QR labels for rapid point-of-sale scanning and stock counts.
• Customer and gold transaction ledger: maintain day-wise, item-wise and customer-wise gold weight balances and cash values for accurate auditing.

I’m open on the tech stack—whether you prefer Flutter, React Native, Laravel, .NET or another modern framework—so long as the UI is fast and intuitive for in-store use and the database can scale as the catalogue grows.

Please outline:
• The architecture you propose (front end, back end, database).
• Any ready-made libraries or POS hardware integrations you would leverage.
• Milestones you expect for a usable MVP and for complete module delivery.

Once the finished build is installed on our devices, I’ll test each module against real transactions; payment is released per milestone on acceptance. Looking forward to your approach.
