This research was conducted at a company engaged in manufacturing, called Coffee Station. This research aims to find out how the accounting information system is implemented and the implementation of internal control of raw material inventory at the Coffee Station. This research method uses a qualitative method with a descriptive approach. Data collection techniques used were documentation and interviews with several employees at the Coffee Station. The results of this research indicate that the implementation of the raw material inventory accounting information system is still carried out manually, due to human resources who are less competent in the fields of accounting and computerization. However, they have implemented good procedures so that there is no shortage of raw material supplies. The implementation of internal control over raw material supplies has not been fully effective. Company management has implemented several internal control concepts and principles, however manual recording can pose risks to the company and in control activities there are still dual functions in the purchasing and recording of raw materials.
