Project Overview

Introduction

The Inventory Management System is designed to automate and simplify inventory operations for small and medium businesses. Traditionally, inventory records are managed manually in spreadsheets or registers, which increases the chance of human errors and inconsistencies. This web-based application replaces manual processes with a structured, centralized solution.

With Django as its framework, this system ensures scalability, security, and robust data handling. It integrates multiple business modules — such as suppliers, products, sales, purchases, and returns — to provide a complete and synchronized view of business activities.

Available Features

After carefully examining the project files and implemented Django apps, the following core modules and features are present in the system:

Usage Guide

Once the system is up and running, users can interact with it based on their assigned roles. The system primarily supports two types of users — Admin and Staff.

1. Admin Role

Admins have full control over the system. Their tasks include:

• Managing users, suppliers, and customers.
• Adding new products and defining categories.
• Monitoring stock levels and generating financial reports.
• Managing purchases, returns, and expenses.
• Accessing and analyzing business performance through dashboards.

Admins can log in to the Django admin interface using the credentials created via createsuperuser. From there, they can oversee every operational aspect of the business workflow.

2. Staff Role

Staff members have restricted access compared to admins. Their primary functions include:

• Recording sales transactions.
• Registering new customers and updating existing profiles.
• Managing returns and checking product availability.
• Viewing purchase and expense summaries (if permissions allow).

All actions performed by staff are logged, ensuring transparency and traceability for the admin.
