## Overview

This is an inventory-management ERP with a React interface backed by a Laravel application. Users sign in, navigate operational views, and manage stock, warehouses, transfers, transactions, reports, users, and settings; the React context coordinates state and API requests, while Laravel controllers handle domain operations and Eloquent models represent persistent records. The README is empty, so product scope comes from the source tree and named pages/modules. Several controllers and the API client were not excerpted; their connections are omitted or marked unverified rather than inferred as direct calls.

Main entry points: [`src/App.tsx`](https://github.com/rolzkie/inventorytracking/blob/main/src/App.tsx) (App shell), [`backend/app/Services/InventoryNotificationService.php`](https://github.com/rolzkie/inventorytracking/blob/main/backend/app/Services/InventoryNotificationService.php) (Alerts and notices), [`backend/routes/api.php`](https://github.com/rolzkie/inventorytracking/blob/main/backend/routes/api.php) (HTTP routes), [`backend/app/Models/InventoryItem.php`](https://github.com/rolzkie/inventorytracking/blob/main/backend/app/Models/InventoryItem.php) (Inventory items)
