A business with several sites and outsourced service dependencies may need a different audit programme from a single-service organisation. Compare certification-body proposals against the same scope, accreditation requirements and ongoing audit commitments.
ANAB, IAS or JASANZ: what are you actually choosing?
ISO/IEC 27001 is the management-system standard. An independent certification body audits your organisation and decides whether to issue a certificate. ANAB—the ANSI National Accreditation Board—IAS, the International Accreditation Service, and JASANZ are accreditation bodies: they assess certification bodies. They are not three different grades of ISO 27001.
Check that the proposed certification body holds current accreditation for ISO/IEC 27001 and that the certificate's scope fits the services, legal entity and locations your buyer needs covered. International recognition can support acceptance, but it does not override a tender's conditions. If a customer specifies an accreditation or permits an equivalent, clarify acceptance in writing before you book.
A certificate does not guarantee a government contract. If certification covering the work being purchased is mandatory, an unsuitable scope may leave your bid non-compliant. Meeting that requirement still does not replace the buyer's other participation conditions or evaluation criteria. Read the specific procurement documents and seek clarification where needed.
Why can the price differ? You buy certification from a certification body, not from an accreditation logo. Audit time, complexity, sites, travel, rates, follow-up work and the ongoing audit programme affect the quote. Compare Stage 1, Stage 2, surveillance and recertification on the same scope. Do not assume ANAB is always dearer, IAS is always cheaper, or that a customer's country alone determines which certificate it will accept.
