How Much Does ISO Certification Cost?
Every ISO project is unique — but the cost of certification generally falls into predictable categories. Here’s what to expect, what it depends on, and how to budget wisely.
Cost Factor 1: Internal Preparation
This includes internal labor, documentation development, and readiness consulting. The more you can prepare internally, the lower the external cost.
Cost Factor 2: Implementation Support
Consulting fees for system design, gap closure, and training vary by project complexity and scope — ranging from a few thousand to tens of thousands depending on organization size and baseline readiness. These figures generally apply to ISO 9001, 14001, and 45001. ISO 27001 typically requires a more intensive deployment and comes with significantly higher associated costs due to its security and technical control requirements.
Cost Factor 3: Registrar Audit Fees
Accredited certification bodies charge based on audit time, which depends on your number of employees, locations, and processes. Expect registrar fees of $5,000–$15,000+ for initial certification and surveillance years. McCann Consulting assists clients in selecting a suitable registrar and obtaining upfront pricing based on ISO-required audit days. This removes surprises and allows for more accurate budgeting early in the process.
Cost Factor 4: Ongoing Maintenance
Maintaining certification requires internal audits, surveillance, and continual improvement. Many organizations budget annually for external support, audits, and system refinement.
Optional Add-On: Pre-Certification Gap Assessment
Some businesses opt for a one-time assessment to understand their current state and build a cost-based roadmap to certification. McCann Consulting offers this as a standalone service.
