🆚 Go to Comparative Table 🆚

The main difference between internal and external audits lies in their purpose, scope, and the parties involved. Here are the key differences between the two:

  1. Purpose: Internal audits focus on a company's performance, risk management, and operational efficiency, while external audits concentrate on proving the accuracy and veracity of financial statements.
  2. Scope: Internal audits usually cover a wider range of areas within the organization, including financial reporting, compliance, information security, operations, risk management, and more. External audits are primarily focused on financial information and records, and they are usually limited to a specific period of time, such as a year.
  3. Auditor: Internal auditors work within an organization as employees, while external auditors are independent of the organizations they audit.
  4. Relationship to Company: Internal audits are conducted by the organization's own audit department or employees, whereas external audits are carried out by an independent third-party audit firm.
  5. Reporting: Internal audit reports are typically presented to senior management or the chief audit executive, while external audit reports are shared with stakeholders, such as investors, creditors, and lenders.

In summary, internal audits are conducted by company employees and focus on a company's performance, risk management, and operational efficiency, while external audits are conducted by independent third parties and focus on the accuracy of financial statements. Both types of audits are essential for ensuring the accuracy and integrity of a company's financial information and practices.
