I will develop a windows grocery store pos system with mobile app
DarshanSingh
About this gig
Running a grocery store with a notebook, an old billing software, or three
disconnected apps? I build a complete Point-of-Sale ecosystem that actually
fits how a grocery store works one till app for the counter, one mobile
app for the owner, and clean data that never gets mixed up between stores.
WHAT YOU GET
️ Windows POS App (for the store counter)
Role-based login Owner, Manager, Cashier, each with different access
Barcode scanning to add products and bill customers in seconds
Full product & inventory management with low-stock alerts
Purchase management from suppliers, with supplier records
Sales, invoices, and receipt printing
Cash register opening/closing with reconciliation
Sales history with fast invoice search

Discounts and promotions
Expiry date tracking alerts for expired and soon-to-expire stock
Cash or POS terminal payment when "terminal" is selected, the total
is pushed straight to your card machine; payment is completed there,
not re-entered
Full activity log of every user action
One-click backup & restore
Sales, inventory, and profit reports
Mobile App (Owner & Managers)
Secure login, separate from the till app

FAQ
What tech stack do you use?
Windows POS app in C# (.NET, WPF/WinForms) with SQL Server or SQLite for local + cloud sync. Mobile app in Flutter (single codebase for Android & iOS). Backend/API in Node.js or FastAPI, with Firebase or a REST API for real-time sync between the counter and the mobile app.
Can it work without internet at the store counter?
Yes — billing, barcode scanning, and inventory work fully offline on the Windows app. Once internet is back, sales sync to the mobile app and cloud reports automatically.
I already have a barcode scanner / thermal printer / POS terminal. Will it work?
Most USB/Bluetooth barcode scanners and ESC/POS thermal printers work out of the box. For a specific POS terminal (card machine) integration, message me the model first — terminal APIs vary by provider (PayTM, Pine Labs, Ezetap, etc.) and this affects scope/price.
Can I add more stores later?
Yes, the Premium package is built for it — each new store is just a new isolated account, no re-architecture needed.
Do I own the source code?
Yes, full source code is handed over on final delivery, no licensing lock-in.
What do you need from me to start?
A list of your product categories, staff roles, your printer/scanner models if you already own them, and your GST/tax setup for the invoice format.
