A service catalog is a document that contains structured and detailed information with the descriptions of services provided, their identification labels, ownership and liability, and the costs affiliated with them. The procedure to ask for any service and the steps to the stated service’s delivery are mentioned in the catalog. It also consists of the escalation points, contacts, and Service Level Agreement (SLA) data. Service Catalog Management consists of catalog processing, updating of information and making sure that it is accurate. It aims at providing exact and precise information on the services that are undertaken whenever needed. It gives an overall picture of the available services for future references.

The two types of service catalogs are-

1. Business (Customer) service catalog- contains details of the IT services provided to the customers and their relation to the business units and business processes.
