Explanation of audits
Audits are systematic and independent examinations of an organization’s financial, operational, or compliance processes, policies, and procedures. The primary purpose of audits is to provide an objective assessment of an organization’s internal controls, governance, and risk management practices. Audits help to ensure that an organization is complying with relevant laws, regulations, and industry standards, as well as identifying opportunities for improvement in processes and procedures.
Audits are conducted by a third-party auditor or by an internal auditor within the organization. The auditor follows a structured approach, which involves gathering evidence, evaluating that evidence, and drawing conclusions based on that evidence. Audits can be conducted on different aspects of an organization, such as financial statements, internal controls, IT systems, or supply chain management.

Differences Between Internal and External Audit
While both internal and external audits involve an independent examination of an organization’s processes, policies, and procedures, there are some key differences between the two.
Here are some of the main differences between internal and external audit:

- Reporting Line: Internal auditors report to the management of the organization, while external auditors are appointed by the organization’s shareholders or board of directors and report to them.
