Up-to-date information is one of the main business resources for companies. This has brought about the creation of a number of government supported bodies assisting businesses in their legal operation. Nevertheless, the lack of information is still recognized as the key problem for businesses. To minimize the gap in B2G communication, the European Union (EU) member states, in cooperation with the European Commission, have created so called Points of Single Contacts (PSCs) – portals providing access to exhaustive information on existing administrative requirements for businesses. Unfortunately, the quality of the mentioned PSCs differs considerably from country to country. In the paper with a help of Classification and Regression Decision Tree method there is provided the evaluation of the efficiency of the Latvian PSC. Based on the analysis of the current flaws of the Latvian PSC, an improved model of the PSC was elaborated. The efficiency of the current and the improved PSC is determined with the help of entropy coefficient.
