What each figure means

First-time vs recertification
First-time covers building the system and getting certified. Recertification is the ongoing cost once you already hold the certificate, including surveillance audits and the year-three renewal.
Company size
Headcount is the biggest driver of audit length. More employees means more audit days, which raises the cost.
Process maturity
If you already document how you work, there is less to build, so implementation costs less. Starting from scratch costs the most.
How you will do the work
Consultant-led is faster but adds fees. In-house is cheaper in cash but uses far more of your team's time. "Some outside help" sits in between.
Extra sites
Each additional location adds audit time and implementation effort, because auditors need to see how the system works across the business.
Implementation (total)
The people cost of building the management system: consultant fees plus your own staff's time. This is usually the largest line.
Initial certification audit
What the certification body charges for the stage 1 and stage 2 audits to issue your certificate. Driven by audit days and the standard's complexity.
Surveillance audit (per year)
A shorter check each year to confirm you are keeping the system running. A recurring cost for the life of the certificate.
Recertification audit (year 3)
The renewal audit at the end of the three-year cycle. Lighter than the first certification, heavier than a surveillance visit.
3-year cost of ownership
The realistic total across a full three-year cycle, not just year one. This is the number to budget against.
