The ability to add, edit, and delete item data ensures that the system remains synchronized with physical inventory, reducing discrepancies that often plague manual inventory systems. This functionality supports efficient warehouse operations by enabling quick adjustments when receiving new stock or processing sales orders. Analysis of Black Box Testing Results The application of Equivalence Partitioning technique in black box testing has proven effective in validating the system's core functionalities. This testing methodology, as referenced by Hidayat & Muttaqin . , allows for systematic evaluation of input conditions and expected outputs without requiring knowledge of the system's internal structure. The successful rejection of incorrect login credentials (Scenario . confirms that the authentication mechanism functions correctly, preventing unauthorized access and maintaining system security. This is a critical validation point as authentication serves as the first line of defense against security threats. The system's ability to distinguish between valid and invalid credentials demonstrates robust input validation and error handling mechanisms. The validation of new item data addition (Scenario . verifies the integrity of data persistence operations. The successful storage of new items in the database indicates that the system correctly implements database connectivity, data validation, and transaction This functionality is fundamental to the system's primary purpose of maintaining accurate inventory records. Proper data validation at the input stage helps prevent data corruption and ensures that only valid information is stored in the database. The stock validation mechanism (Scenario . represents a particularly critical business logic implementation. The system's ability to prevent outgoing transactions that exceed available stock demonstrates intelligent constraint enforcement, which is essential for preventing inventory errors and stock-out situations. The warning message feature provides users with immediate feedback, allowing them to take corrective action before completing the transaction. This prevents negative inventory balances and maintains data integrity, which is crucial for accurate financial reporting and operational planning. The successful generation of PDF reports with accurate data (Scenario . confirms the system's capability to produce standardized documentation for auditing and management PDF format is widely recognized as a reliable medium for report distribution due to its platform independence and consistent formatting across different devices. The accuracy of the data in these reports is crucial as they may be used for financial auditing, compliance verification, and strategic decision-making. Practical Implications The successful implementation and testing of this inventory management system offers several practical benefits for warehouse operations. First, the user-friendly interface reduces the learning curve for staff members, facilitating faster adoption and minimizing training costs. Second, the real-time monitoring capabilities enable proactive inventory management, allowing organizations to optimize stock levels and reduce carrying costs while avoiding stockouts. The security features implemented in the system address contemporary concerns about data protection and access control. As warehouses often manage high-value inventory and sensitive business information, the authentication and encryption mechanisms provide necessary safeguards against both external threats and internal misuse. Limitations and Future Work While the current implementation demonstrates functional success, several areas could be enhanced in future iterations. First, although black box testing has validated key functionalities, comprehensive testing including white box testing, integration testing, and user acceptance testing would provide additional confidence in system reliability. Second, performance testing under high-load conditions would be valuable to ensure the system can scale as warehouse operations grow. 98 | Journal of Business. Social and Technology Siti Nur Fatonatur Rohma. Oscar Agyemang Opoku Design Get up. Future enhancements could include integration with barcode or RFID technology for automated item tracking, mobile application development for on-the-go inventory management, and advanced analytics features such as demand forecasting and automated reorder point Additionally, implementing role-based access control with multiple user levels would provide more granular security management suitable for larger organizations with complex operational hierarchies. CONCLUSION This research successfully demonstrates that waterfall methodology effectively supports web-based inventory system development for SMEs with well-defined requirements. At CV. Tekno Maju Jaya, the implemented system achieved significant operational improvements: stock discrepancies reduced from 22% to under 2%, monthly reporting accelerated from 72 hours to real-time access, and manual data entry time decreased by 85%. Black-box testing confirmed 100% functionality across all 25 test scenarios. Scientifically, this study validates waterfall applicability for resource-constrained SME contexts and provides replicable frameworks for digital transformation in developing countries. The research demonstrates that modern web frameworks (Laravel 10. PHP. MySQL) deliver enterprise-level functionality at minimal cost, advancing SME technology adoption literature. However, limitations include single-case design restricting statistical generalizability, six-month timeframe precluding long-term sustainability evaluation, and absence of comprehensive performance testing. Future research should explore agile methodologies and conduct longitudinal studies on SME system scalability.
