ISO/IEC 20000-1 Certification Cost

We don’t publish a fixed price, because cost depends on organisation size, number of locations, scope, process complexity, audit duration, consulting requirements and certification body fees. Request a scoped estimate and we’ll walk you through each factor.

Certification Timeline

Timelines depend on organisational readiness, scope and the complexity of your processes. A well-prepared, single-site organisation typically moves faster than a multi-site or highly regulated one — we’ll give you a realistic timeline after the initial gap analysis.

ISO 20000-1 vs ITIL

ITIL is a best-practice framework that describes how to implement ITSM processes, while ISO 20000-1 is a certifiable standard that defines the audit requirements for an IT Service Management System. They are complementary.
