Introduction
Auditing is an integral part of corporate governance. It provides assurance that business operations, controls, and financial statements are reliable and compliant.
However, not all audits are the same. The two most commonly discussed types are Internal Audit and Statutory Audit. Although they may seem similar, both serve very different purposes.
