In this era of Industrial Revolution 4.0, adaptation to the IoT is becoming a must to maintain competitiveness in logistic operation. SMEs in Malaysia must deal with problems in logistic operations, such as the inability to track the location of delivery accurately and monitor racking status. These cause logistical problems that include excessively expensive costs from inefficiencies in task management and workflow processes, overstocking, and frequent disruptions in the supply chain due to delayed or misplaced items. Therefore, to design a user-friendly, secure, and cost-effective IoT system focused on delivery monitoring and racking that could provide SMEs with in-transit real-time visibility and control of their logistic operations. The provided solution was developed through the exploitation of Google's suite of web-based software for its development: Google Sheets to host the database, Google AppSheet to provide the functionality for a mobile application, and Looker Studio as a business intelligence tool for visualization and display of tracking and monitoring data. After implementation in several SME warehouses in Malaysia, it proved to be successful in fully utilizing the This integration provides SMEs with in-transit visibility and control over their logistics. The rack percentage that was missing in the factory before the implementation of the system was very alarming, standing at 35%. This percentage later dropped dramatically to just 1% after the implementation of the system. Following a series of successful deployments in various Malaysian SME warehouses, the system proved to optimize operations and reduce the complete chain of waste in the warehouse.
