ISO auditing services USA provide the independent verification your organization needs to achieve and maintain certification while protecting your supply chain from compliance risk. AGS Iraq, an ANAB-accredited certification body, delivers comprehensive audit solutions across the United States—from certification audits that grant your ISO certificate to supplier audits that vet your vendors and outsourced internal audits that fulfill Clause 9.2 requirements with objective expertise. Unlike consultants who implement systems, our practicing auditors verify conformance against international standards, identifying non-conformances before they become costly failures. Whether you are an automotive supplier in Detroit preparing for IATF 16949 certification, a defense contractor in Seattle requiring AS9100 compliance, or a medical device manufacturer in Boston navigating FDA QMSR requirements, our auditing services ensure you pass with confidence.
Compliance assurance—the confidence that your management system meets all requirements and will withstand external scrutiny—depends on rigorous, independent assessment. When audits reveal non-conformances after certification is granted, the consequences include:
Your certification audit is scheduled. Your team has worked for months. Then the auditor finds a major non-conformance. Your certification is delayed. Revenue is lost.
Our gap analysis and pre-assessment services function as your “dry run” before the formal certification audit. By identifying weaknesses early, you:

ISO 9001 certification audits typically range from $8,000–$20,000 for small to medium organizations, depending on employee count, site complexity, and number of locations. Surveillance audits run $8,000–$12,000 annually. Gap analyses cost $3,000–$6,000 and can save up to 50% on certification costs.
Stage 1 is a documentation review and readiness assessment conducted on-site or remotely. It confirms your system is designed to meet requirements. Stage 2 is the full implementation verification, where auditors observe processes, interview staff, and test controls. Stage 1 must be completed before Stage 2.
Yes. ISO standards require internal audits to be objective and impartial. Outsourcing to qualified third-party auditors fulfills Clause 9.2 requirements while providing expertise your internal team may lack. AGS offers fully managed internal audit programs nationwide.
AGS conducts supplier audits anywhere in the USA. Our network of industry-specific auditors serves automotive suppliers in Detroit, aerospace vendors in Seattle, medical device manufacturers in Boston, and energy companies in Houston. We handle travel, scheduling, and reporting.
Major non-conformances require root cause analysis and corrective action within 60 days, with verification audit typically required. Minor non-conformances require corrective action by the next surveillance audit. AGS provides post-audit support to help you close findings successfully.
From Stage 1 to certificate issuance typically takes 3–6 months, depending on your readiness. Stage 1 requires 1–2 days, Stage 2 requires 2–5 days depending on organization size, and report processing takes 2–4 weeks.
Check three things: (1) The certification body's ANAB/IAS accreditation status on their public registry, (2) Individual auditor credentials (IRCA/Exemplar Global certificate numbers can be verified online), and (3) Industry experience through references.
Auditors verify conformance and grant/withhold certificates; they cannot help you implement systems due to independence requirements. Consultants help you build and improve systems but cannot certify you. AGS provides both services through separate, independent teams.
AGS provides auditing services nationwide. Our auditor network covers all 50 states, with concentrations in major industrial hubs. Contact our team to discuss your specific location requirements.
