An accounting system is a series of procedures and methods used to record, process, and report the financial transactions of an institution. Problems arise when companies with partners or subsidiaries integrate financial data and information, but companies with partners use different accounting system platforms. It is very difficult to integrate transactions and information from several different accounting system platforms. Thus, the purpose of this research is to adopt blockchain technology for transactions in the accounting system. Blockchain technology requires every transaction involving parties in the accounting system to go through a peer-to-peer validation process that ensures the transparency of each transaction. The concept of distributed storage in blockchain technology will increase the security of transactions in the accounting system. This research focuses on discussing transactions for purchasing goods from suppliers and selling goods to distributors, which are the initial stages of the accounting system. The research will also discuss blockchain technology-based buying and selling transactions and their relationship to the stages in the next accounting system. The research uses a qualitative approach through a literature review of the phenomena and problems of conventional accounting systems. A literature review is also used to study the conceptual model of blockchain technology with the accounting system in previous research as a reference for creating a proposed model. The research output is a proposed model and simulation with the Hyperledger framework.
