Applying Accounting Information System Theory on Computers in the Payment Cycle

The accounting information system is divided into three major subsystems: the transaction processing system (TPS), the general ledger/financial reporting system (GL/FRS), and the management reporting system (MRS). The payment cycle is a subcycle of an accounting information system's transaction processing cycle. The study systematized accounting information system theory, accounting information systems in the computerized billing cycle, including System Flowcharts to depict the cycle and internal control activities to evaluate the cycle. The study evaluated and documented the accounting information system throughout the payment cycle at Duc Thanh Packaging and Trading Production Co., Ltd., evaluating the system's benefits and limits. The study proposes solutions to complete the system according to the realities of the Duc Thanh company, such as solutions for task division between the liabilities accounting department and the payment accounting department, as well as solutions for independent verification between the payment accounting department and the bank.
