Design and Development of Retail POS and Inventory Management System Using PyQt6 and SQLite3

Small retail businesses often face difficulties in managing products, inventory, sales transactions, and sales records efficiently when using manual or paper-based methods. These methods may result in inaccurate inventory records, calculation errors, and difficulties in tracking sales information. This project aims to design and develop a desktop-based Retail Point of Sale (POS) and Inventory Management System to improve the management of retail operations. The system is developed using PyQt6 for the graphical user interface and SQLite3 for local database management. The Research and Development (R&D) approach is applied to identify system requirements, design the system architecture and database, develop the user interface and core functions, and plan system testing. The proposed system includes product management, inventory management, sales transactions, search functionality, stock monitoring, tax and discount calculation, and sales reporting. The system is expected to provide a simple and efficient solution for managing retail products, inventory, and sales while reducing manual work and improving data accuracy.
