Supplier audits in manufacturing: a practical playbook

In manufacturing, supplier audits are how customers know your supply chain is safe. Keep the evidence live and audits become polite check-ins, not fire drills.

What a good supplier audit record contains

  • Quality certificates (ISO 9001, IATF 16949).
  • Environmental (ISO 14001).
  • Health & safety (ISO 45001).
  • Material certificates and test reports.
  • Traceability documents per batch.
  • Insurance and financial evidence.

The continuous-audit posture

Instead of scrambling before a customer audit, keep evidence current all year. A live Credbase pack means the auditor sees today's documents, not a snapshot from three months ago.

Handling multi-site suppliers

Model each site as its own record if certificates differ. Roll up per-supplier for the boardroom view; drill down per-site for the audit.
