Supplier Qualification Audit

A buyer with a certification obligation cannot simply place an order with a new shop. It has to establish that the supplier can hold the requirement repeatedly, and record that it established it.

A desk audit reviews documents: the quality manual, certification certificates and their scope, procedures, calibration records, and financial standing. It is the cheaper form and it is often enough for lower-risk work.

An on-site audit adds a visit. An auditor walks the floor, checks equipment and calibration, reviews traceability, and examines how nonconformance is handled. For medical device and aerospace work it is frequently mandatory rather than optional.

Findings produce corrective action requests. A finding is not automatically disqualifying: the supplier responds with a corrective action, the buyer verifies it, and the audit closes. That exchange is normal and it takes time.

Passing places the supplier on the buyer's approved supplier list, which is what actually permits purchase orders to be issued. Certification qualifies a supplier for requests for quote in a category; the audit qualifies it for one buyer.

This is why the industrial buying cycle typically spans several months to more than a year, and why the incumbent supplier holds an advantage unrelated to price. The audit cost is paid again for every replacement.

For a supplier, the audit is also a content opportunity that most shops miss. Publishing what a buyer would find in a desk audit shortens it: certification scope, calibration programme, inspection equipment, traceability approach, and how nonconformance is handled. A buyer able to complete most of the desk review from the website starts from a shorter list of questions.
