InventoryPro — Offline Inventory Shop Management Mobile App

A fully offline Flutter ERP for shops, boutiques, pharmacies, and small retail businesses. Run POS checkout, inventory, purchases, sales invoices, accounting, payroll, and manufacturing — all without a server. Your data stays on-device with Realm, and an optional documented web-sync API is included for developers who want to connect their own backend.

Works with zero internet connection. No server, no monthly hosting, no downtime — the shop keeps selling even when the network doesn’t.
One app, full back-office. POS, inventory, purchasing, accounting, payroll, and manufacturing in a single Flutter codebase.
Built for real shop operations, not a generic CRUD demo: barcode scanning, GRN receiving, multi-warehouse stock, installment sales, and low-stock alerts are all wired end to end.
Ready to resell or white-label. Business name, currency, tax, language, brand colors, and app icon are all easily customizable.

Optional Web Sync

InventoryPro runs standalone by default — no backend required. For teams that want multi-device or connected mode, the package includes a documented outbox/sync-engine architecture and a full HTTP API contract (WEB_SYNC_BACKEND.md) covering login, push, pull, idempotency, and conflict handling, so developers can connect it to their own server.

No analytics or advertising SDK is included. Business data stays in local Realm storage on the device unless the administrator explicitly configures optional web sync or messaging integrations. Manual backups are portable JSON — store them securely.
