During the past few years, there has been a declining trend on the performance of Indonesian supply chain companies. The performance of the Indonesian supply chain companies is relatively low compared with other countries such as Malaysia, Thailand, and Singapore. To address this issue, the primary objective of this study is to examine the role of computerized accounting system (CAS) in supply chain accuracy. A survey was conducted to collect the necessary data from the managerial staff of supply chain companies in Indonesia. PLS-SEM was implemented to analyze the data. The results indicate that CAS had a significant positive relationship with supply chain accuracy. Computerized accounting system supports supply chain operations, which increases the accuracy of the supply chain system. Computerized accounting system also provides the ease of use and usefulness, which enhances the supply chain activities and decreases various issues. Therefore, the computerized accounting system is the key to gain accuracy in the supply chain.
