## Overview

This is a Django inventory and retail-management application with a public storefront and a staff back office. Shoppers browse products, manage a cart, and check out; staff can also ring up point-of-sale sales, manage purchasing and stock, and review customers, employees, and reports. The sampled views and URL configuration establish the request-routing and data-access layers, while the README is empty. Several feature areas are visible only through routes and templates, so their internal behavior is not expanded beyond supported links.

Main entry points: [`inventory/urls.py`](https://github.com/thinvannika198/ecommerce_inventory/blob/main/inventory/urls.py) (HTTP routing), [`inventory/models.py`](https://github.com/thinvannika198/ecommerce_inventory/blob/main/inventory/models.py) (Inventory domain), [`inventory/views.py`](https://github.com/thinvannika198/ecommerce_inventory/blob/main/inventory/views.py) (Product catalog), [`inventory/static/backoffice/js/pos.js`](https://github.com/thinvannika198/ecommerce_inventory/blob/main/inventory/static/backoffice/js/pos.js) (POS interface)
