Development of a Complete Pharmacy Management System (HTML/CSS/JavaScript) – Full Source Code

I will provide you with a complete pharmacy management system that runs entirely in the browser without requiring a server, external database, or Internet connection. It is built with HTML, CSS, and JavaScript, with data stored locally directly on your device.

The system includes:
- A fast sales screen (cashier) for completing sales and automatically deducting quantities from inventory
- Complete inventory management (adding/editing/deleting medications, prices, and expiration dates)
- Recording supply and purchasing operations and linking them to inventory
- Automatic alerts for low stock and approaching expiration dates
- A complete invoice history with cancellation and refund options
- Sales and profit reports (daily and overall), as well as the best-selling items
- A data backup and restore system (JSON export/import)

You will receive the complete source code, customizable according to your needs (adding a logo, modifying fields, connecting to an invoice printer, supporting multiple users, and more).

Before ordering, you can try the system directly through a demo version intended for viewing only. Contact me for details.
