  • Auditing vs. Investigation: Two Pillars of Financial Accountability

Do you get confused between auditing and investigation? Both terms may sound similar, but they have distinct differences. Auditing is a regular process of checking financial records to ensure accuracy, whereas an investigation involves digging deep into specific areas of concern to uncover fraud or other illegal activities.

Auditing is a systematic examination of financial records, transactions, and processes to ensure accuracy, compliance, and financial integrity. While investigation involves a thorough inquiry or examination to gather evidence and determine the facts related to alleged misconduct, fraud, or other irregularities, often with legal implications.

What is an Audit?

An audit is an independent, objective evaluation of an organization’s financial statements and financial reporting processes. An investigation, on the other hand, is a more focused inquiry into a specific issue or concern.

Audits are typically conducted on an annual basis but can be conducted more frequently if there are concerns about the organization’s financial health. Investigations are usually triggered by specific events or complaints.

The scope of an audit is generally much broader than that of an investigation. An audit looks at all aspects of an organization’s finances, while an investigation focuses on a specific issue.

Audits are typically conducted by external auditors who have no affiliation with the organization being audited. Investigations are often conducted by internal investigators who work for the organization.

What is Investigation?

An investigation is conducted to uncover evidence of wrongdoing. It is initiated when there are grounds to believe that an offense has been committed. An investigation gathers facts and information to determine whether a criminal offense has been committed and, if so, who committed it.

The police have many powers they can use during an investigation. These include the power to stop and search people, enter and search premises, seize property, require the production of documents, and take fingerprints and DNA samples. The police can also question suspects under caution.

During an investigation, the police will gather evidence from a variety of sources. This may include eyewitness accounts, CCTV footage, DNA evidence, and bank records. Once the police have gathered all the evidence they need, they will decide whether or not to charge someone with a crime.

Purpose of Auditing and Investigation

Auditing serves as a systematic and independent examination of financial records, processes, and controls to verify the accuracy of financial information, identify errors or irregularities, and assess compliance with applicable laws and regulations. It helps in safeguarding assets, detecting fraud, and ensuring financial accountability.

Investigations are conducted to gather evidence, determine facts, and address alleged misconduct, fraud, or irregularities. Investigations help in uncovering the truth, identify responsible parties, and take appropriate actions to rectify the situation, protect stakeholders’ interests, and ensure compliance with legal requirements.

Key differences between Auditing and Investigation

  1. Purpose: Auditing is primarily conducted to assess the accuracy, integrity, and compliance of financial records and processes, while the investigation is focused on gathering evidence and determining facts related to alleged misconduct, fraud, or irregularities.
  2. Scope: Auditing typically has a broader scope and covers various financial aspects of an organization, including financial statements, controls, and compliance. The investigation, on the other hand, has a narrower scope and is targeted toward specific incidents or allegations.
  3. Approach: Auditing follows a systematic and standardized approach, often guided by auditing standards and procedures. The investigation, however, involves a more in-depth and flexible approach, tailored to the specific case or incident being investigated.
Differences between Auditing and Investigation


Auditing ensures financial accuracy, compliance, and transparency, reducing the risk of errors and fraud, while investigation focuses on uncovering misconduct, fraud, or irregularities and gathering evidence for potential legal actions. While auditing provides a broader assessment of financial processes, controls, and compliance, the investigation is more targeted and case-specific.
