The main differences between internal and external audits are their purpose, scope, and the auditors who perform them. Here is a summary of these differences:

  1. Purpose: Internal audits focus on measuring current performance, identifying areas for improvement, and ensuring compliance with company policies and regulations. On the other hand, external audits aim to prove the accuracy and veracity of financial statements and provide assurance to stakeholders, such as investors, creditors, and regulators.
  2. Scope: Internal audits usually target specific areas within a company, while external audits focus on all relevant financial information and any other practices that could affect the accuracy of financial statements.
  3. Auditor: Internal auditors are employees of the company they audit, while external auditors are independent third parties, typically from accounting firms.
  4. Relationship to Company: Internal auditors work on behalf of the company and report their findings to senior management or the chief audit executive. External auditors, on the other hand, work independently and report their findings to stakeholders, such as shareholders and creditors.
  5. Compliance Concerns: Internal audits can help companies identify gaps or areas of improvement in their compliance with laws and regulations, while external audits provide an assessment of the organization's compliance with relevant laws and regulations.

In summary, internal audits are conducted by company employees and focus on improvements and compliance, while external audits are performed by independent third parties and aim to provide assurance to stakeholders regarding the accuracy of financial statements.
