Public procurement in Sweden is regulated by the Act on Public Procure­ment (lagen om offentlig upphandling, LOU, in Swedish). The Public procurement in Sweden stands every year approximately for 500 bil­lion Swedish crowns of the taxpayers’ money. It is therefore im­portant that the money is spent in the best possible way. The focus in this study is set on the relationship between the small- and medium sized building entrepreneurs and the government. The study is built on international scientific arti­cles together with Swedish industry articles and the results from our own interview study. A comparison has been made between the three and it has resulted in listing obstacles for SME (small- and medium sizes enter­prises) and how to overcome these obstacles.
