The authority for customer audits at a supplier’s facility is typically outlined in contracts or purchasing agreements.
These documents specify the terms and conditions under which the supplier agrees to allow audits by the customer.
Quality management system documents and certificates of conformance do not usually grant audit authority.
References: The ASQ "Auditing Handbook" and ISO 9001 standards emphasize that contractual agreements define the rights and obligations regarding audits.
