Data analysis was conducted through four stages: system survey, survey findings analysis, information needs identification, and system requirements specification. The system design utilized the Waterfall model with Unified Modeling Language (UML) tools. Furthermore, the MySQL database was applied to facilitate the processing of goods data for sales, ensuring swift, accurate, and efficient marketing efforts. The outcome of this web-based sales information system design is anticipated to enhance operational efficiency in the sales process. This system provides an integrated platform to streamline product management and improve customer access to information. Additionally, the system contributes to optimizing sales processes by reducing manual workloads and increasing data management accuracy.
