ISO 20000
A Complete Guide to ISO 20000 - Service Management Systems
Strong service management makes your services more consistent and your teams clearer on what good looks like. Plus, it makes your customers much more confident in choosing you.
ISO 20000 certification gives you an internationally recognised framework for doing exactly that.
At iso360, we help organisations build service management systems that are practical and certification-ready.

What is ISO 20000?
ISO 20000 is the international standard for service management.
More specifically, ISO 20000-1 sets out the requirements for a Service Management System (SMS): the framework an organisation uses to plan, design, deliver, monitor, and continually improve its services.
While the standard is often associated with IT service management, it’s actually relevant to any organisation that manages and delivers services to internal or external customers. So, that might include managed service providers, cloud providers, SaaS businesses, IT outsourcing companies, and internal IT teams.
ISO 20000 certification demonstrates that your organisation has a structured, repeatable approach to service delivery. It shows customers, partners, and procurement teams that you can manage service quality, respond to issues, meet agreed requirements, and keep improving over time.
Certification itself is awarded by an independent certification body. When you work with iso360, we’ll help you prepare for that process and build a system of service management processes that work hard for you long after the certificate is displayed on the wall.
Benefits of ISO 20000 certification?
From our experience of working with clients, the journey to ISO 20000 often starts with a client requirement or tender question, but there’s so much more value to it.
-
Win and retain business
The most obvious benefit is that larger customers increasingly want reassurance that their suppliers can deliver reliable, well-managed services. ISO 20000 certification can help you meet procurement requirements and give prospective clients greater confidence in your operations, setting you apart from others who are also in the tendering process. -
Deliver a more consistent service
Things can get missed if service expectations, responsibilities, and processes are unclear. An effective SMS, backed up by the ISO 20000 standard, brings structure to how services are designed, delivered, supported, and improved. Best practice in action. -
Reduce avoidable disruption
ISO 20000 encourages a proactive approach to incidents, service requests, recurring issues, suppliers, capacity, continuity, and change. It helps you identify weak points before they spiral into bigger problems for your customers. -
Give teams a clearer way of working
Having the standard in place helps your team understand what's expected of them and where decisions sit internally. Plus, it shows them how to keep delivering a consistent customer experience as your business grows. -
Build trust alongside other certifications
ISO 20000 works particularly well alongside standards such as ISO 27001 for information security and ISO 9001 for quality management. Together, they can create a stronger, more joined-up approach to risk and customer confidence.
What are the ISO 20000 requirements?
ISO 20000 does not prescribe one fixed way of managing services – it’s far from a one-size-fits-all situation.
Instead, it asks you to establish a service management system shaped around appropriate to your organisation, customers, and services.
Your SMS will need to cover areas such as:
- The scope of your services, customers, and service-management responsibilities
- Leadership, ownership, roles, and objectives
- Service planning and service delivery controls
- Service portfolios and service-level agreements
- Customer, supplier, and business relationship management
- Demand, capacity, availability, and service continuity
- Information security within the service-management system
- Incident, service request, and problem management
- Service design, change, and transition
- Performance monitoring, internal audits, and management reviews
- Corrective action and continual improvement.
This will look different for every business. A fast-growing SaaS provider should not have the same system as a large, multi-site managed service provider.
Our goal is to create enough structure for you to deliver reliable services and evidence that structure at audit.
ISO 20000, ITIL, and ISO 27001: what is the difference?
| FRAMEWORK OR STANDARD | WHAT IT DOES |
|---|---|
| ISO 20000 | A certifiable international standard for service management systems. |
| ITIL | A service-management framework that can help shape processes and practices, but is not a certification standard for organisations. |
| ISO 27001 | A certifiable standard for information security management systems. It focuses on protecting information; ISO 20000 focuses on managing and improving services. |
You do not need to adopt ITIL to achieve ISO 20000 certification. Equally, if you already use ITIL practices, they can provide a useful foundation.
ISO 20000 and ISO 27001 can also be integrated, helping you manage service quality and information-security risk in a more connected way.

What does the ISO 20000 certification process look like?
Although every organisation’s path to certification is slightly different, this is what you can typically expect from the ISO 20000 implementation processes.
1. Understand your starting point
We begin with a gap analysis to understand what you already have, what is working well, and where the gaps are. You may have more in place than you think. Perhaps it just needs bringing together, formalising, or evidencing properly.
2. Define a realistic scope
The scope sets out which services, teams, locations, and activities are covered by your SMS. Getting this right early prevents unnecessary complexity later on.
3. Build or strengthen your SMS
We help you put the right framework in place, including policies, processes, roles, service controls, and reporting. Everything is tailored to your organisation rather than copied from a template.
4. Embed it into day-to-day operations
A system only works if people can actually use it. We help make sure your processes fit the way your teams work, with practical guidance around evidence, ownership, and continual improvement.
5. Prepare for audit
Before certification, you will need to complete an internal audit and management review. We can support both, helping you identify and address issues before an external auditor does.
6. Achieve and maintain certification
The certification body completes its independent audit. Once certified, you will need to maintain your SMS, respond to findings, and keep improving ahead of surveillance and recertification audits.
Who is ISO 20000 for?
ISO 20000 is particularly relevant for organisations that provide technology-enabled services, including:
- Managed service providers and IT support companies
- SaaS and software businesses
- Cloud service providers
- IT outsourcing and consultancy firms
- Data centre and hosting providers
- Internal IT teams supporting a wider organisation
- Businesses bidding for contracts with demanding service-management requirements.
You may be ready to explore ISO 20000 if clients are asking tougher questions about service delivery, your team is growing quickly, or your current processes rely too heavily on individual knowledge.
What you can expect to have in place
By the time you’re ready for certification, you should have a clear and usable SMS that includes:
- An agreed ISO 20000 scope
- Defined service-management roles and responsibilities
- Documented processes that reflect how your organisation works
- Clear controls for service delivery, incidents, changes, suppliers, and performance
- Evidence that the system is operating in practice
- Internal audit and management-review records
- A realistic plan for continual improvement.
Frequently asked questions about ISO 20000
Is ISO 20000 only for IT companies?
No. It is most commonly used by IT and technology service providers, but it can apply to any organisation that manages and delivers services to customers.
Do we need ITIL to achieve ISO 20000 certification?
No. ITIL can be useful, but it is not a requirement. ISO 20000 focuses on whether your service management system meets the standard’s requirements and works effectively in practice.
Does ISO 20000 replace ISO 27001?
No. ISO 20000 focuses on service management, while ISO 27001 focuses on information security. Many organisations choose to integrate the two because both support stronger, more reliable service delivery.
How long does ISO 20000 certification take?
There isn’t a single answer to this question, because it depends on your current level of maturity, the size and complexity of your service operation, and the scope of certification. A gap analysis is the best place to start, as it gives you a realistic picture of the work involved.
Can a small business achieve ISO 20000 certification?
Yes, absolutely. The system should be proportionate to your business. A smaller provider does not need a large-company framework; it needs a clear, effective approach that is appropriate to its services and customers.
Can iso360 issue your ISO 20000 certificate?
No. Certification must be independently awarded by an accredited certification body. iso360 prepares your organisation for audit, supports implementation, and helps you build a sustainable system.
