An inventory management system keeps an organisation’s stock accurate day to day: what’s on hand, what’s running low, what’s been received and what’s gone out. This project adds role-based permissions and clean exports, which makes it a strong, well-rounded portfolio piece.

Core features

  • Dashboard overview of stock health
  • Item, category and product management
  • Warehouse management for multiple locations
  • Order and stock movement tracking
  • User management with dynamic role permissions
  • Export to CSV / Excel and print-ready views

Why role permissions matter here

In a real warehouse, a clerk shouldn’t be able to delete products or change permissions. This system lets you create multiple roles and choose exactly which pages and actions each role can reach — a clean, practical example of access control you can reuse everywhere.

Technology stack

Built with PHP on the CodeIgniter framework and MySQL. A typical setup imports a small schema (for example an ims_db database) and runs on XAMPP or any PHP host.

Setup overview

  1. Download and extract the source.
  2. Create a database (e.g. ims_db) and import the SQL file.
  3. Place the code in your web root and open it in the browser.
  4. Sign in as the seed admin and configure roles.

What you’ll learn

Stock movement modelling, multi-warehouse data design, dynamic permissions, and producing clean CSV/Excel exports from PHP.

Frequently asked questions

Can it handle more than one warehouse?

Yes — that is a built-in concept here; each stock record belongs to a location, so transfers between warehouses are just movements.

How are exports generated?

The app queries the current view and streams it as CSV or an Excel-compatible file for download or printing.

A note on using this project

This guide is written to help students and developers understand how a PHP/CodeIgniter application like this is designed and built. Treat any sample code as a learning reference: read it, run it locally, and adapt it to your own requirements rather than shipping it unchanged. If you reuse third-party components, check their licences first.
