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.
