Comprehensive and Detailed Explanation From Exact Extract of Documents:

A compliance audit evaluates whether an organisation adheres to regulatory requirements, security policies, and internal risk management procedures. The L5M5 study guide (p.207) highlights that this is distinct from external audits (conducted by outsiders), third-party audits (commissioned independently), and benchmarking audits (comparing against industry peers). Procurement professionals must use compliance audits to ensure suppliers meet legislative and regulatory standards, reducing risks of non-compliance, fines, and reputational damage.
