A single regional market provides plenty of advantages to its members. The European Union (EU) has created a legal framework to remove frontiers between its members, so companies originating from one country can freely operate in any other EU member state without meeting additional administrative requirements. The practical efficiency of the created framework to a significant extent depends on national governments. Based on the qualitative analysis of the EU legal acts, the author proposes a model of implementation of the principle of free movement of goods and services. In the paper the system of relevant activities and the corresponding tasks is presented as a matrix for elimination of obstacles to sell goods or provide services in the common EU market.
