A supplier audit checks whether a supplier actually operates the way they claim — that their quality systems, delivery processes, compliance and financial controls are sound enough to rely on. Auditing consistently protects your supply chain from disruption and reputational risk. This free checklist gives you a structured set of audit questions across quality, delivery, compliance, health and safety, and financial controls, with a pass/partial/fail rating on each and an automatic overall audit score in the Excel version — plus a print-ready PDF for on-site use.
Why audit your suppliers
Selecting a supplier well is not the end of due diligence. An audit verifies that their systems and controls hold up in practice — before a quality escape, a delivery failure or a compliance breach becomes your problem.
It also drives improvement. A structured audit surfaces specific, evidenced gaps and turns them into corrective actions with owners and dates, rather than a vague sense that a supplier 'could do better'.
How to use this supplier audit checklist
Run the checklist for each audit:
- Complete the header — supplier, site, auditor and audit date.
- Work through each question, rating it Pass, Partial or Fail with evidence.
- Let the Excel version total the section scores and overall audit score.
- Log a corrective action, owner and due date for every gap you find.
- Share the completed audit with the supplier and track actions to closure.
Supplier audit best practices
Scale the depth of the audit to the supplier's risk and importance — audit critical suppliers more thoroughly and more often. Base every rating on evidence you have seen, not assertions. Agree corrective actions with clear owners and deadlines, and re-audit to confirm they are closed. Pair the audit with a vendor risk assessment so risk and operational performance are assessed together.
