This method causes various problems such as inaccurate data, the risk of losing cash recapitulation, and delays for the owner in monitoring financial conditions and making decisions. This study aims to design and build a web-based sales information system and profit and loss monitoring system that can integrate transaction processes and present computerized financial reports. The development method used is Waterfall, including requirements analysis, design, implementation, testing, and maintenance. The analysis technique used is Black Box Testing, while the system is built using PHP, MySQL, and DFD and ERD modeling. The results show that the system was successfully built and functions properly. This system facilitates customers in placing orders and confirming payments online, as well as assists the manager in managing products, orders, deliveries, and presenting profit and loss reports in real-time and accurately.]]>
