The main difference between IT services and consulting is that IT services provide solutions and expertise to help companies create and improve business processes, while IT consulting focuses on providing strategic advice on how to modify or improve solutions to achieve the desired objective. At a high level, IT consultants offer guidance to clients on a wide range of topics, from general IT strategy - such as what to host in the data center instead of in the cloud - to the type of technology and functionality needed in the context of the customer's business and IT environments and objectives, such as process automation or mobile security. Having access to experienced IT professionals is invaluable for some companies. A technical consulting firm provides an organization with access to expert best practices, that is, knowledge gained from working with many companies, for as long as they need. Your IT service provider could take on the role of consultant instead of you hiring someone trained solely in IT consulting.
IT consulting services are consulting services that help clients evaluate different technological strategies and, in doing so, align their technological strategies with their business or process strategies. In addition to being called IT consulting, a company that offers this service can also be referred to as technology consulting, computer consulting, business and technology services, or computer consulting. That said, just because IT professionals offer IT consulting as part of IT services doesn't always mean that they provide other IT services.
