Analisis Efektivitas Sistem Informasi Akuntansi Pembelian : (Studi Kasus PT. ABC)

This study examines the effectiveness of the purchasing accounting information system at PT. ABC, with an emphasis on the quality and timeliness of information from ordering to payment to vendors. Using a qualitative descriptive approach, data was obtained through interviews, observations, and documentation involving departments related to purchasing activities. The results show that although the system has been implemented in accordance with company procedures, its effectiveness is still not optimal. This is evidenced by inconsistent documentation, frequent invoice revisions, and delays in the verification and payment processes, which reduce the efficiency and reliability of information. These problems are caused by weak document control, limited interdepartmental coordination, inadequate human resources, and high workloads in the purchasing unit. Therefore, improvements in system implementation and internal control are needed to improve the accuracy, timeliness, and overall effectiveness of the purchasing accounting information system.
