This thesis studies the transformation to utilizing e-business in corporate business activities. This transformation is called e-transformation. The transformation requires changes in both the IT infrastructure, as in the way things are done within the company. In this thesis the most focal needs for change are evaluated and solutions are suggested for the utilization of e-business at the corporate level. E-business sets demands to the corporate level management of customers, users and products. Also new kinds of demands are set to the IT systems used. A major practical problem in e-transformation is the growing need for the integration of corporate databases and information systems. In this thesis methods are sought to perform this integration. As an example, the challenges relating to the development of a CRM-system were examined. In this thesis the aim was to develop a model for an electronic portal with the help of which centralized electronic services can be offered to customers. In addition to the developed model, possible development phases were studied in the transformation to a portal as well as presenting a model of a multilevel portal.
