ISO Audit
Your Customer Requires ISO Certification. Your Last Internal Audit Was Eighteen Months Ago.
ISO 14001 and ISO 45001 certifications require ongoing internal audits, management reviews, and corrective action tracking. If you're only thinking about compliance when the registrar shows up, you're carrying risk between visits. iSi keeps your management system audit-ready year-round.
ISO Audit Services
Audits conducted to ISO 19011 guidelines. Independent auditors. Findings classified and actionable recommendations — not compliance theater.
ISO 14001 Internal Audit
Systematic audit of your environmental management system against ISO 14001 requirements. Covers policy, planning, support, operations, performance evaluation, and improvement.
ISO 45001 Internal Audit
Audit of your occupational health & safety management system. Worker consultation, hazard identification, risk assessment, operational controls, and emergency preparedness.
Integrated Management System Audit
Combined 14001 + 45001 audit for facilities running both systems. Identifies shared processes, redundancies, and integration opportunities.
Gap Analysis & Certification Prep
Pre-certification assessment for facilities pursuing initial ISO certification. Maps current state against standard requirements. Identifies every gap before the registrar arrives.
Surveillance Audit Preparation
Get ready for your registrar's annual surveillance visit. Review findings from last audit, verify corrective actions closed, update document control, and run a mock audit.
Management Review Support
Facilitate the management review process required by both standards. Compile inputs, run the meeting, and document outputs — decisions and actions related to improvement.
Compliance Gaps Most Facilities Miss
These scenarios look compliant on the surface. Underneath, they carry nonconformity risk. We see them at nearly every facility we audit for the first time.
Internal Audits Happen — But Always By the Same Person
ISO requires auditor independence. If the person auditing a process is also the person managing it, the audit doesn't satisfy the standard. Registrar nonconformity: major finding.
Major nonconformity from registrar = inability to maintain certification. Loss of ISO certification means loss of customer contracts that require it.

Corrective Actions Logged But Never Verified
Your CAPA system shows actions were assigned. But no one verified they were actually implemented and effective. ISO requires verification of corrective action effectiveness. This is one of the most common nonconformities across both 14001 and 45001.
Registrar finding: Minor nonconformity, but carries forward to next audit cycle. Recurring findings can trigger heightened audit frequency or loss of certification.

Management Review Is a Slide Deck, Not a Decision
ISO requires management review to produce outputs: decisions and actions related to improvement. If your review is a presentation without documented decisions, it doesn't meet the standard.
Registrar finding: Nonconformity for missing or inadequate management review outputs. This triggers corrective action requirements and may delay recertification.

Audit-Ready. Certification-Ready. Revenue-Protected.
Losing ISO certification means losing customer contracts that require it. For manufacturers in aerospace, automotive, and defense supply chains, certification loss can put $50,000–$150,000+ in annual revenue at risk. iSi's internal audit and certification prep services maintain a 92% first-time pass rate with registrars.
What You Get: The ISO Audit Report
Every ISO audit project delivers a complete report — not a raw checklist. The report includes findings classified as major nonconformity, minor nonconformity, or opportunity for improvement, with corrective action recommendations and root cause analysis.
Reports are written for management and operations leaders — clear findings, prioritized recommendations, and next steps for registrar readiness. No padding. No filler. Your team reads it once and knows exactly what to do.
Beyond the Certificate — The System That Runs Without You
The point of ISO isn't the certificate on the wall. It's the management system that runs consistently whether you're there or not. iSi's audit services don't just check boxes — they build the underlying system that makes your operations repeatable, scalable, and defensible.
When a customer asks "how do you manage your environmental/safety program?" the answer is documented, systematic, and auditable. That answer becomes your competitive advantage — and your legal protection.

ISO Audit Questions
What ISO standards does iSi audit against?
ISO 14001:2015 (environmental management) and ISO 45001:2018 (occupational health & safety). We also support integrated management system audits combining both standards. Note: iSi is a consulting partner, not a certification body — we prepare you for the registrar.
How much does an ISO internal audit cost?
Starting at $3,500 depending on scope, number of processes, and facility size. Compare to the revenue at risk if certification lapses — most manufacturers can't afford to lose their ISO status.
How often should we conduct internal audits?
ISO requires a complete audit cycle covering all processes. Most organizations plan this across 12 months. High-risk processes should be audited more frequently. iSi can run your entire internal audit program or supplement your internal team on specific processes.
Can iSi help us get certified for the first time?
Yes. We start with a gap analysis against the standard, build a corrective action roadmap, help implement the management system, run internal audits, and prepare you for the Stage 1 and Stage 2 registrar visits.
