<![CDATA[The development of information technology encourages companies to improve data management efficiency and business process integration. Procurement, sales, inventory management, payment, and transaction recording processes that are not optimally integrated may lead to data redundancy and errors in information management. This study aims to design and develop a web-based Enterprise Resource Planning (ERP) application that integrates various business processes into a centralized system. The system was developed using the Scrum method, which supports an incremental and flexible development process according to user requirements. Data collection methods included observation, interviews, and literature review. The development process involved preparing the product backlog, system implementation, and testing using the Black Box Testing method. The result of this study is a web-based ERP application named Synchro, which integrates product, customer, and vendor management, Sales Order, Purchase Order, Delivery Order, Goods Receipt, invoice and payment management, General Journal, and General Ledger. This integration enables data related to procurement, sales, inventory, and transaction recording to be managed within a single system. The developed features include purchase and sales transaction management, goods receipt and delivery recording, inventory monitoring, invoice and payment management, and accounting journal recording. Black Box Testing was conducted to examine whether the system functions met the specified functional requirements. Based on the test results, the tested features operated according to their expected functions. Therefore, the Synchro ERP application provides a centralized system that supports business process integration and more structured information management.]]>
