WEBSITE-BASED ONLINE CASHIER APPLICATION USING RAPID APPLICATION DEVELOPMENT METHODOLOGY

Abstract

The rapid growth of information technology has encouraged the adoption of digital systems in the food and beverage (F&B) industry, particularly in café operations. However, many cafés still rely on conventional cashier systems, resulting in inefficiencies, data inconsistencies, and delays in reporting. This study aims to design and develop a web-based online cashier application to support transaction management and improve operational efficiency in cafés using the Rapid Application Development (RAD) methodology. The RAD method was chosen due to its iterative and flexible development process, which is suitable for small- to medium-scale systems. The development stages include requirement planning, system analysis, design modeling, development, and implementation. The developed system supports real-time transaction recording, role-based user access, order processing, and sales reporting. The implementation results indicate that the system improves coordination between cashier, kitchen, and waiter, reduces transaction errors, and enhances service efficiency. Therefore, the proposed system can serve as an effective digital solution to support operational management and digital transformation in the café sector.
