The inversion of reduction of confidence in combination with the need to face lack of resources for public administration has led governments and various governmental institutions to develop and propagate the services of electronic government. Investing millions in these services governments seek for measures and models that will quantify and highlight the profits that come up from these investments. Initially we present a short literature review of the existing indicators applied by the European Union and institutions that measure citizens’ satisfaction from the use of electronic government services , as well as the relevant research evaluation models. Afterwards, focusing on the scientific gaps that exist, a conceptual model of citizen acceptance satisfaction with E-government services is proposed and developed. Implications for further research and possible modification to the model are also proposed.
