QMS Internal Auditing
Independent audits that find it before your certification body does
ZLG plans and executes your internal audit program with true independence per ISO 19011 — process audits, system audits, remote, on-site, and multi-site — and follows findings through to verified closure.
An internal audit program your certification body respects: independent auditors, defensible evidence-based findings, and corrective actions that close and stay closed.

Challenges this service solves
- Auditing your own processes compromises impartiality
- The audit schedule exists on paper but keeps slipping
- Internal audits never find what external auditors find
- Findings are vague, disputed, and slow to close
- Multi-site audits need consistency you cannot staff
- A surveillance or certification audit is coming and coverage is incomplete

Questions
Frequently asked
How do you maintain independence when auditing our QMS?
ZLG auditors have no responsibility for the processes they audit, which satisfies the impartiality expectations of ISO 9001, ISO 13485, AS9100, and IATF 16949. Findings are based strictly on objective evidence, and confidentiality is protected under our engagement agreement.
Can you run our entire internal audit program?
Yes. We can develop your audit program, plan and execute process and system audits (remote, on-site, or multi-site), write nonconformities, deliver reports, and follow up on corrective actions — or supplement your existing audit team for specific audits.
