The accountability system in Indonesian oil and gas companies faces several critical problems such as low process efficiency, insufficient transparency, and a high potential for operational cost corruption and fraud. This study aims to analyze a business process of operating accountability cost using a cash card system in a shared service center in one Indonesian oil and gas company using Business Process Management. Business Process Management is performed by modeling and simulating the current (As-Is) process. Modeling As-Is process using iGrafx with Business Process Modeling and Notation (BPMN). Process management aims to understand the various activities related to the organization's operations and improve their efficiency. This study aims to identify processes that can be improved to reduce manual processes and time constraints. The proposed solutions are based on best practice methods that can be used to improve business processes. The researcher also suggested reviewing the entire process of making a new cash card so that users do not have to wait long to complete the process.The accountability system in Indonesian oil and gas companies faces several critical problems such as low process efficiency, insufficient transparency, and a high potential for operational cost corruption and fraud.
