## Inventory & Sales

A subscription app for iOS and Android, for any small business that keeps stock on a shelf: parts counters, tire and phone shops, market stalls and small warehouses. We built it at NPCoding in 2026 as a product of our own.

- **Item templates** for batteries, tires and phones, plus a generic one. You can add your own fields.
- **VAT-aware prices**: type a price with or without VAT and see both. Profit is worked out from the purchase cost.
- **Scanning**: a barcode or QR code with the camera or a Bluetooth scanner, to sell, restock, count a shelf or find an item.
- **Stock-outs by reason**: sale, bonus, warranty replacement or return. Any change can be undone.
- **A pending list**: customers who paid but haven't picked up yet, and units a supplier still owes you.
- **Low stock**: an alert when an item is running out, and a reorder list by supplier.
- **Shelf counts and locations**: check every difference before it changes your stock, and keep stock in more than one place.
- **Reports and export**: sales and profit, stock-outs by reason and stock value, plus Excel export and printable barcode labels.
- **No signal needed**: everything is saved on the phone, so the app works offline.
- **English and Hebrew**, with a full right-to-left layout in Hebrew.

## How it's built

The app is written in **React Native** with **Expo**, and the data lives in a **SQLite** database on the phone — no account, no ads and no server, with a daily backup kept on the phone itself. Subscriptions run through **RevenueCat** on Apple's and Google's stores.

The app is on its way to the App Store and Google Play. Store links will be added here once it's live.
