Internal Audit

Internal audit is the independent appraisal of activity within an organization for the review of accounting, financial and other business practices. Internal audit is conducted by the business itself for a continuous basis. Internal audit is done by the internal staff appointed particularly for the audit purposes.

If an independent auditor examines the books and records of the company on the behalf of the shareholders, it is called external audit.
