A complete Point of Sale (POS) Management System built in PHP and MySQL using PDO queries, with free source code you can download and run locally.
This POS system is a ready-to-use retail sales and inventory solution for students, capstone projects, and small businesses that need a working cashier and stock-control application. It handles both cash and credit sales, tracks inventory automatically, and generates a full set of sales and accounting reports out of the box.
What Is the POS Management System?
The Point of Sale (POS) Management System is a PHP/MySQL web application that lets a shop record sales transactions, manage products and stock, handle customers and suppliers, and produce receipts and reports. It is written with the PDO database layer, which uses prepared statements and is a safer, more modern way to talk to MySQL than the old mysql_* functions.
