PHP Ecommerce Inventory Management Site

I need a straightforward PHP-based website that lets me sell physical goods while keeping every product detail fully under my control. From the admin panel I want to, that can be accesible on laptop as well as mobile

• Add or remove products at any time
• Edit titles, descriptions, prices, tax percentages and delivery fees
• Track current inventory levels automatically

On the storefront the buyer must see the tax and delivery charge broken out clearly, but the actual billing summary should appear on a separate page so I can update that layout later without touching the product catalogue.

Please build it with clean PHP and a MySQL database (or another open-source equivalent if you prefer). Keep the code modular and well-commented so new fields or reports can be dropped in easily. When the work is finished I’ll need:

• A SQL file to create the tables
• Source code for all PHP, HTML, CSS and any JS you use
• Brief setup notes so I can move it to my hosting

If you’ve already built lightweight ecommerce or stock-tracking tools in plain PHP, this should feel familiar. Let me know your timeline and any clarifying questions you have before starting.
