The United States' Trusted Audit & Inspection Partner

AuditCo delivers independent audit, inspection, and assurance services to certification bodies, enterprises, and regulated industries across the United States, backed by the same rigorous standards we apply worldwide.

Audit and Certification Services Across the United States

Independent. Experienced. Built for the demands of American industry.

Operating compliantly in the United States means navigating a federal baseline with real state-by-state variation layered on top. OSHA sets the national floor for workplace safety under the OSH Act, but several states, including California, Washington, and Michigan among them, run their own OSHA-approved State Plans with additional requirements.

Add ISO certification through ANAB-accredited bodies, the FDA’s Quality System Regulation for medical device manufacturers, FSMA for food businesses, and CMMC for anyone in the defense supply chain, and it’s a compliance landscape where getting the details right, jurisdiction by jurisdiction, genuinely matters. AuditCo’s US clients trust us to navigate that complexity with them, not around them.

AuditCo’s US team delivers independent audits against ISO 9001, ISO 14001, ISO 45001, ISO 27001, and ISO 42001, with certification work aligned to ANAB accreditation requirements. Our auditors bring direct sector experience across the industries central to the American economy, including telecom, oil and gas, manufacturing, construction, logistics, and information security, with the state-level regulatory knowledge to support clients operating in multiple jurisdictions at once.

We know that in the US, “compliant” can mean something different depending on which state you’re standing in. Our team plans every engagement around that reality, so audits stay accurate to both the federal baseline and whatever your state adds on top.
