The most flexible no-code ITSM solution
What is a Service Catalog?
A service catalog is a centralized, organized listing of IT services offered to users within an organization. Each entry typically includes a description, request process, delivery time, and any requirements or approvals needed.
In IT Service Management (ITSM), the catalog is closely tied to service request management. It defines what the IT team offers and how those services are delivered. Without a catalog, service desks often rely on generic request forms or unstructured communication channels.
The catalog isn’t a static list; it’s designed to be actionable. Users interact with it through a portal, often selecting predefined options that trigger automated workflows in the ITSM tool.
Why is an IT service catalog important?
Without a service catalog, IT teams often operate reactively — fielding unstructured requests, clarifying vague tickets, and managing services through tribal knowledge rather than documented workflows. That kind of approach makes it harder to scale, automate, or measure performance. It also creates a frustrating experience for users, who aren’t always sure how to get what they need or what to expect once they submit a request.
A well-structured catalog changes that. It defines available services in business terms, connects them to fulfillment processes, and sets clear expectations for both users and IT. Over time, it becomes a foundation for improving service quality, speeding up delivery, and making IT operations more predictable.
Companies that adopt service catalogs often use them to support internal accountability. Service-level targets can be tied directly to catalog entries. Ownership is easier to assign. And cross-functional services — like onboarding or access provisioning — can be broken down into steps, assigned to different teams, and tracked from end to end.
3 benefits of having an IT catalog of services
Once a catalog is in place, both IT teams and users benefit from the structure it brings:
- Standardized service delivery: A catalog makes teams define how each service should be fulfilled, by whom, and under what conditions. That structure reduces guesswork and variation, making it easier to introduce automation, meet SLAs, and identify process issues without relying on individual effort.
- Improved user experience: Giving users visibility into available services, along with guided forms and status tracking, reduces reliance on support channels. It also prevents unnecessary delays caused by incomplete or misrouted requests, which often stem from a lack of clarity rather than user error.
- Operational visibility and control: Once requests flow through catalog-defined paths, IT can collect reliable data on volume, response times, bottlenecks, and service gaps. This creates a clearer picture of demand and performance, which is difficult to get from unstructured tickets or ad hoc processes.
Service catalog vs. self-service portal vs. service portfolio
These terms may seem similar and are often used together, leading to confusion. However, each serves a different purpose in IT Service Management.
- Service catalog: This is the structured list of services that are available to end users. It includes descriptions, request forms, fulfillment processes, SLAs, and any conditions or approvals tied to the service. It’s used internally by IT teams and also exposed to users to guide their requests.
- Self-service portal: This is the interface, usually within the help desk software, where users interact with the service catalog. It may include knowledge articles, FAQs, and other support tools, but its main role is to let users browse available services, submit requests, and track their status.
- Service portfolio: This is the broader view of all services managed by IT—past, present, and planned. It includes retired services, those in development, and those currently offered. The catalog is essentially a subset of the portfolio, focused only on services actively available to users.
What should a service catalog include?
A well-structured service catalog brings clarity to both requesters and providers. To serve its purpose, it should include the following components:
- Service categories: Groupings that help users browse and IT teams organize offerings, such as hardware, access, applications, or facilities.
- Service entries: Each entry defines a specific service available to users, including a name, a short description, and request availability.
- Request criteria: Key input fields or required information needed to process the request correctly, often tied to a form.
- Fulfillment details: A general outline of how the request is processed, including automated tasks or manual steps. This is not always visible to users but is critical for internal consistency.
- Approval rules: If applicable, the catalog entry should indicate when a request needs authorization and who grants it.
- Expected delivery timelines: Estimated response or resolution times that set expectations and align with SLAs.
- Service ownership: A designated contact or team responsible for reviewing, updating, and maintaining the entry over time.
How to build a service catalog?
Building a service catalog takes planning and coordination. According to ITIL, the catalog is part of the service design stage, where services are defined before they’re introduced into operation. That makes it not just a documentation task, but a design activity that shapes how services will be delivered and supported.
Here’s how to approach the process step by step:
1. Identify the services in scope
Start by mapping out what services IT currently delivers to the business. Use historical ticket data, team documentation, and interviews with support staff to build your initial list. Don’t worry about perfect definitions at this stage — focus on identifying what people are actually requesting and receiving today. Include both technical services (like password resets or laptop provisioning) and business-enabling services (such as onboarding support or access to tools).
It’s also worth clarifying what won’t be included yet. You can start with the most requested or high-impact services, then expand.
2. Define service entries
Once you have your list, structure it into service entries that can be published. Each entry should clearly describe:
- What the service is
- Who can request it
- What the service does and doesn’t include
- Any prerequisites or eligibility requirements
Avoid vague labels. Instead of “Software,” specify “Request a new licensed software installation” or “Install company-approved free tools.” Collaborate with service owners or process stakeholders to make sure the descriptions reflect actual delivery capabilities.
3. Organize by category
Create categories that make sense to your users. The goal is to help them find what they need quickly, not to reflect how your IT team is structured. Keep the list navigable and avoid adding too many layers. Organizing services into categories like “Accounts and access,” “Hardware,” or “New hire setup” helps users scan and select the right option faster.
Also, don’t create too many categories or overly technical names. A good rule is to test the structure with real users before going live. Use analytics from your portal to refine over time based on search terms or misrouted requests.
4. Design request forms
Work with the teams who fulfill each service to define what information is necessary to start the process. The goal is to reduce back-and-forth while keeping the request form as simple as possible for the user.
Include conditional fields if needed, based on user input. For example, a hardware request might show additional questions depending on the type of equipment selected. Consistency matters here — forms that vary widely in tone or detail can cause confusion.
5. Add fulfillment logic and SLAs
Define what happens after a request is submitted. Map out the internal workflow:
- Who reviews and approves the request (if anyone)
- Who fulfills it
- How long it usually takes
- What dependencies are involved (e.g., inventory availability)
This step creates alignment between the catalog and your operations, laying the groundwork for automation in tools like your ITSM platform.
Tying SLAs directly to catalog entries also helps teams understand what happens when things go off track. As Linda Lenox said in Ticket Volume Episode 96:
“You can’t fix what you don’t understand. When SLAs are missed, it’s not about making excuses—it’s about identifying the why and addressing the root cause.”
When structured this way, the catalog doesn’t just document service delivery — it becomes a tool to improve it.
6. Publish and maintain
Deploy the catalog in your self-service portal, making sure everything is accessible and easy to use. Set a review schedule so services stay current, especially when processes change or new services are introduced. Services change over time, and outdated entries cause confusion. Maintenance can also include reviewing metrics, updating SLAs, or rewording request forms based on support feedback.
How InvGate can help with Service Catalog Management
InvGate Service Management gives IT teams the tools to create, manage, and publish a service catalog that’s easy to maintain and intuitive for end users. You can define each service with its own request form, approval flows, and fulfillment steps, all without needing to write code.
Services are published through a customizable service portal that lets users browse available services by category, submit requests with the right information from the start, and track progress. The platform supports role-based visibility, so users only see the services that apply to them. This helps avoid confusion and reduces unnecessary requests. You can also tie services to SLAs and use automation to route tickets or trigger follow-up actions based on conditions you define.
Service owners have access to metrics on how often each service is requested, how long it takes to fulfill, and where delays happen. These insights help you keep the catalog relevant and identify areas for improvement over time.
And if you're also using InvGate Asset Management, you can connect asset data to service requests, making it easier to associate things like laptops, printers, or licensed software with service actions.
5 service catalog best practices
These best practices to build a service catalog can help you keep it usable and scalable:
- Always keep users’ needs in mind: Creating a successful IT service catalog is about people’s needs. Involve users and stakeholders in the development and ongoing management of the service catalog.
- Use language that makes sense to requesters: Avoid technical labels or internal jargon. Write service names and descriptions from the requester’s point of view so they can identify the right option without help.
- Be flexible: Services change, and so should the catalog. As service delivery becomes more responsive, your catalog should support that. Along with the catalog, you will have metrics on performance to allow your teams to adjust, as Shane Carlson put it in Ticket Volume Episode 88:
“With the observability we have today, we can compare what’s happening to the outcomes we want and make real-time decisions.”
- Standardize request forms: Align how services collect information to make it easier to fulfill requests and train support teams. Consistency also improves the user experience.
- Build in automation where possible: Automating common fulfillment steps — like sending confirmations or assigning tickets — saves time and reduces delays.
