Auditing vs. Investigation: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 20, 2023
Auditing evaluates financial statements for accuracy, while investigation is a detailed examination of a specific issue or concern.

Key Differences

Auditing and investigation both serve as methods of scrutinizing information, but they differ in purpose, scope, and depth. Auditing primarily refers to the systematic process of examining financial statements to ensure they are accurate, complete, and in accordance with established guidelines or standards. It is a regular procedure, often annual, to validate the correctness of accounts and ensure transparency in financial reporting.
In contrast, investigation delves into specific areas or issues when there's a suspicion of wrongdoing or to gain clarity on a particular matter. While auditing is a routine and broader examination, an investigation is usually more focused, analyzing particular transactions or events in depth. For example, if discrepancies arise during an audit, an investigation may be initiated to understand the cause and effect of such anomalies.
The intention behind auditing is to provide assurance to stakeholders, such as shareholders, that financial statements present a true and fair view of a company's financial position. This is usually carried out by external auditors who are independent of the organization. On the other hand, investigation aims to uncover facts, identify causes, or provide evidence. It can be instigated for various reasons, ranging from suspected fraud to due diligence for business acquisitions.
To put it simply, while both auditing and investigation involve careful examination, they differ in their objectives. Auditing seeks to affirm, providing confidence in the integrity of financial statements. Meanwhile, investigation seeks to uncover, diving deep into specific areas to retrieve detailed information or evidence.
