<![CDATA[TB Bangun Jaya is a building materials store that still manages manual stock recording and sales transactions, so there are often recording errors, delays in reporting, and difficulties in tracking goods data. This problem shows the need for an information system that is able to integrate stock management and payments efficiently and accurately. This research aims to design an integrated information system that can support the operational process of TB Bangun Jaya. The system development method with the waterfall model, and the data collection techniques used include observation, interviews, and literature studies, with a structured system development approach. The result of this study is a system design that includes context diagrams, DFD Level 0, DFD Level 1, ERD, which represent the process of managing data of goods, transactions, and reporting. This design is expected to be the initial solution in the digitization of store business processes. Further research is recommended to proceed to the stage of system implementation, functionality testing, and development of cloud-based features so that the system can be accessed online and in real-time.]]>
