Accounting controls are the procedures and policies that an organization puts in place to ensure the accuracy, completeness, and security of its financial data. These controls can range from something as simple as a segregation of duties and double-entry bookkeeping to more complex measures such as physical and cyber security protocols. By doing so, organizations are better able to prevent fraud, identify mistakes, and establish trust with their stakeholders. In short, accounting controls provide the framework for a successful and secure financial system.
