Welcome to Build a Complete Stock Management System with Vanilla PHP & MySQL! In this practical, hands-on project course, you will learn how to design, architect, and code a full-featured Inventory and Sales Management System from the ground up. By skipping heavy frameworks and working directly with Vanilla PHP, you will gain a deep, fundamental understanding of core web development, SQL query optimization, database security, and transaction processing.
Why Vanilla PHP First?
Frameworks like Laravel hide the underlying magic. When you build a complex project in Vanilla PHP, you master the foundational concepts—database normalization, session security, master-detail relationships, and PDO transactions—that make you a significantly stronger developer in any framework or language.
What We Will Build Together
Throughout this course, you will construct a fully functional 10-table relational database system step-by-step:
- 1. User Authentication & Role Control: Secure login system using PHP sessions and password_hash() encryption with role-based access (Admin, Manager, Staff).
- 2. Catalog & Entity Management: Complete CRUD interface for Brands, Categories, Suppliers, and Customers (including customer/supplier due balance tracking).
- 3. Product Inventory Registry: Product catalog with unique SKUs, cost pricing, selling pricing, real-time stock counts, and custom low-stock threshold triggers.
- 4. Stock-In / Purchasing Module: Record incoming stock from suppliers using master-detail headers (purchases) and line items (purchase_items), automatically incrementing product quantities.
- 5. Stock-Out / Sales & Invoicing Module: Create professional sales invoices (sales and sale_items), track discounts, handle multiple payment methods, and automatically decrement inventory.
- 6. Interactive Admin Dashboard: Build a central hub with visual indicators for total sales, total customers, total suppliers etc.
