Internal access abuse is a form of fraud that can significantly harm a company, both financially and reputationally. Therefore, it is essential for companies to implement effective preventive measures to protect the integrity of their information systems and assets. This article discusses various strategies that can be applied to prevent fraud, including the implementation of strong internal controls, segregation of duties, and strict access controls. Additionally, features such as audit trails, clear security policies, and the use of advanced security technologies are key elements in detecting and preventing access abuse. Building a culture of ethics and transparency within the company, as well as providing ongoing education and training to employees, is also crucial for raising awareness of fraud risks. Conducting regular audits and risk assessments can help companies identify potential weaknesses in their internal control systems.

The purpose of this study is to analyze the implementation of Accounting Information Systems (AIS) in managing the company's revenue cycle control. The revenue cycle involves a series of crucial activities such as receiving orders, shipping goods, billing, and receiving payments, which require strict supervision to reduce errors and manage existing risks. Without the implementation of AIS, some common problems that often arise in managing the revenue cycle include inaccurate information, loss of employee data archives, difficulty in detecting errors in supervision, as well as limited reporting supervision and invalid data. As a solution, AIS can be implemented to increase data processing capacity, improve storage space, and improve control between parts of the organization. This study investigates the implementation of AIS in recording revenue transactions and its impact on internal control, such as preventing fraud, increasing data accuracy, and accelerating business processes. The results of the study are expected to provide an understanding of how the implementation of AIS can improve revenue cycle control and reduce risks associated with large business transactions.
