What You Are Actually Paying For With ISO 20000
ISO 20000 is the international standard for IT service management. It is built around ITIL principles and gives organisations a formal framework for delivering, managing, and continually improving IT services. If you run an IT department, a managed service provider business, or a technology company that delivers services to clients, this is the certification your customers and government procurement teams will eventually ask for.

Before we talk numbers, it helps to understand what the certification process actually involves. Unlike simpler standards, ISO 20000 certification requires you to demonstrate a functioning IT service management system (SMS). That means documented processes, defined service levels, change management procedures, incident management workflows, and evidence that your team actually follows all of it. The auditor is not just checking your paperwork. They are looking at how your services are planned, delivered, and reviewed in practice.
If you want a solid grounding in what the standard actually requires before you start budgeting, the ISO 20000 beginner's guide covers the core requirements in plain language.
The Honest Cost Breakdown for ISO 20000 Certification
There is no single price for ISO 20000 certification. What you pay depends on the size of your organisation, the complexity of your IT services, how mature your existing processes are, and which consultant and certification body you choose. That said, here are realistic cost ranges based on what businesses in Australia and globally are actually spending.
Consultant Fees
Most businesses pursuing ISO 20000 will need a consultant, at least for the gap analysis and documentation phase. Unless you have someone in-house who has implemented the standard before, trying to do it entirely on your own is a significant risk. The standard has 37 clauses and sub-clauses covering everything from service continuity to supplier management, and getting the structure wrong early costs you more to fix later.
For a small IT company with 10 to 30 staff, consultant fees typically range from $8,000 to $20,000 AUD. For a mid-sized MSP or IT department with 50 to 150 staff, expect to pay $20,000 to $45,000 AUD. Larger enterprises with complex service portfolios or multiple locations can see consultant costs exceed $60,000 AUD.
These figures cover gap analysis, SMS documentation, internal audit support, and preparation for the Stage 1 and Stage 2 certification audits. If you want to understand how fixed-price and hourly consulting arrangements compare, the ISO consultant pricing guide breaks that down clearly.
Certification Body Fees
The certification body is the accredited organisation that conducts your Stage 1 and Stage 2 audits and issues your certificate. Their fees are calculated based on auditor days, which in turn are driven by the scope of your SMS and the number of people covered by it.
For a small organisation, certification body fees for the initial certification cycle (Stage 1, Stage 2, and the first year of surveillance) typically fall between $6,000 and $14,000 AUD. Mid-sized organisations should budget $14,000 to $30,000 AUD. Large or complex organisations can pay considerably more.
It is worth noting that certification body pricing is not uniform. Two accredited bodies quoting on the same scope can differ by 30 to 40 percent. This is one of the strongest arguments for getting multiple quotes before you commit.
Internal Costs
This is the category that catches most businesses off guard. Your staff will spend significant time on this project. Someone needs to own the SMS, attend audit interviews, collect evidence, and manage the corrective action process. For a small company, that might be one person spending 20 to 30 percent of their time over six to twelve months. For larger organisations, it is often a dedicated project team.
If you factor in staff time at a loaded cost rate, internal costs for a small to mid-sized company commonly add $10,000 to $30,000 AUD to the total. These costs do not appear on any invoice, but they are very real. The hidden ISO certification costs article covers this in detail and is worth reading before you finalise your budget.
Tools, Templates, and Software
You will need a way to manage your SMS documentation, track non-conformities, and store audit evidence. Some businesses use SharePoint or Google Drive and spend nothing extra. Others invest in purpose-built management system software, which can cost anywhere from $2,000 to $10,000 AUD per year depending on the platform and user count.
Off-the-shelf ISO 20000 template packs are available online for $500 to $3,000 AUD. These can accelerate your documentation phase, but they need to be adapted to your actual processes. A template that does not reflect how your team works is worse than no template at all, because it creates a gap between your documented system and your real one that auditors will find quickly.

Total Cost Summary by Organisation Size
Pulling all of this together, here is a realistic total cost range for ISO 20000 certification in Australia:
- Small IT company (10 to 30 staff): $25,000 to $50,000 AUD all-in for initial certification
- Mid-sized MSP or IT department (50 to 150 staff): $50,000 to $100,000 AUD all-in
- Large enterprise or complex scope: $100,000 AUD and above
These are total project costs including consultant fees, certification body fees, internal time, and tools. They are not worst-case figures. They reflect what businesses actually spend when they approach the certification properly rather than cutting corners.
Ongoing Costs After Initial Certification
ISO 20000 certification is not a one-off cost. Once certified, you enter a three-year certification cycle that includes annual surveillance audits and a full recertification audit at the end of year three.
Annual Surveillance Audits
Surveillance audits are conducted by your certification body once a year (sometimes twice, depending on the body and your agreement). These audits check that your SMS is still operating effectively and that you are addressing any non-conformities from the previous audit cycle.
Annual surveillance audit fees typically range from $3,000 to $8,000 AUD for small organisations and $8,000 to $18,000 AUD for larger ones. You will also spend internal staff time preparing for and participating in these audits.
Recertification Audits
At the end of the three-year cycle, you undergo a recertification audit. This is more thorough than a surveillance audit and is closer in scope to the original Stage 2 audit. Budget roughly 60 to 80 percent of your initial certification body fee for recertification.
Ongoing Consultant Support
Some businesses retain their consultant on a part-time or retainer basis to help maintain the SMS, prepare for surveillance audits, and manage internal audits. This typically costs $3,000 to $10,000 AUD per year depending on the level of involvement. Others bring the capability fully in-house after initial certification, which is the smarter long-term approach if you have the right people.
Running effective internal audits is a key part of keeping your SMS healthy between external audits. The article on how to run ISO internal audits that actually find problems is a practical resource for anyone taking this seriously.
What Drives the Cost Up or Down?
Understanding the key cost drivers helps you make smarter decisions about where to invest and where to save.
Factors That Increase Your Cost
- Immature processes: If your IT service management processes are largely informal or undocumented, you are essentially building the SMS from scratch. This takes more consultant time and more internal effort.
- Multiple service lines or locations: The more services you deliver and the more sites you operate from, the larger your audit scope and the higher your certification body fees.
- High staff turnover: Every time a key person leaves during the implementation, you lose momentum and institutional knowledge. This adds time and cost.
- Choosing the wrong consultant: A consultant who does not understand ISO 20000 specifically (as opposed to ISO 9001 generalists) will take longer and produce weaker documentation. The real cost of choosing the wrong ISO consultant is a sobering read if you are tempted to just go with the cheapest option.
Factors That Reduce Your Cost
- Existing ITIL or ITSM maturity: If your team already operates with structured incident management, change management, and service level agreements in place, you have a significant head start. The documentation and audit evidence already exist in some form.
- ISO 27001 already in place: ISO 20000 and ISO 27001 share common high-level structure elements. Businesses that are already ISO 27001 certified have existing documentation habits, internal audit programmes, and management review processes that transfer directly.
- Focused scope: Certifying a clearly defined, limited scope (for example, one specific service delivered to one client segment) costs less than certifying your entire service portfolio. Many businesses start with a narrow scope and expand it over time.
- Getting multiple quotes: This one sounds obvious, but a surprising number of businesses accept the first quote they receive. Pricing varies significantly between certification bodies and between consultants. Getting three competing quotes can save you 20 to 40 percent on your total project cost.
Is ISO 20000 Worth the Investment?
This is the question every business owner asks, and it deserves a direct answer. ISO 20000 is worth the investment if your customers or procurement processes require it, if you are competing for government IT contracts, or if you are an MSP trying to differentiate yourself in a market full of providers making similar claims about service quality.
In Australia, government agencies at both the federal and state level are increasingly requiring ISO 20000 certification from IT service providers. If you are bidding on government technology contracts, this certification is moving from “nice to have” to “required to tender.” The article on which ISO certification is required for government tenders gives a broader picture of how certification requirements are shaping procurement in Australia.
Beyond contracts, the internal discipline that comes from building a proper SMS has real operational value. Businesses that go through ISO 20000 certification properly report fewer major incidents, faster resolution times, and clearer accountability across their service teams. These are not marketing claims. They are the natural result of documenting your processes, measuring your performance, and reviewing what is not working.
That said, if you are pursuing certification purely for a certificate to hang on the wall without genuine intent to operate the system, you will spend a lot of money for very little return. ISO certification that feels like paperwork is a real problem in the industry, and it is worth being honest with yourself about your motivations before you commit.
How to Get Accurate Quotes for Your Situation
The cost ranges in this article are useful for budgeting, but they are not a substitute for getting quotes specific to your organisation. The two things you need to do are get a consultant quote and get a certification body quote, and you should do both before committing to either.
When requesting quotes, be specific about your scope. Tell providers how many staff are covered, what services are in scope, how many locations are involved, and what your current level of ITSM maturity is. Vague requests produce vague quotes, and vague quotes lead to budget blowouts.
Also ask certification bodies whether they have auditors with specific ISO 20000 experience. ISO 20000 audits require auditors who understand IT service environments. A generalist auditor without that background will struggle to assess your SMS competently, and that creates problems for both parties.
If you want to compare quotes without spending weeks chasing providers individually, CertBetter makes this straightforward. You submit one form describing your organisation and certification goals, and you receive up to three competing quotes from vetted ISO consultants and accredited certification bodies. The service is free for businesses, and it is specifically designed to help you compare providers on a like-for-like basis rather than trying to decode wildly different quote formats on your own.
