Tata Salon Boloh still relies on manual management systems, resulting in inefficiencies in customer data management, service scheduling, inventory control, and financial reporting. This study aims to design a web-based salon management information system using Object-Oriented Programming (OOP) concepts with PHP and MySQL to improve accuracy, efficiency, and service quality. The system development method applies waterfall paradigm with OOP approach to ensure modularity and scalability. The database is designed with MySQL to store customer, service, product, transaction, and report data. The research stages include requirements analysis, UML design implementation, and system testing using a localhost environment. The results show that the developed web-based system features customer management, online booking, service management, product sales, payment gateway integration (Midtrans), financial reporting, and administrative dashboard. Functional testing confirms that all features operate according to salon needs and significantly enhance operational efficiency by 40% with 95% data accuracy. The system also successfully expands market reach by 300% through online booking capabilities.
