Eastern Europe and Scandinavia offer a considerable number of investment and business opportunities

There are multiple reasons for business to invest in Eastern Europe. Some companies are attracted by growing economies and the increasingly wealthier middle class. Others simply want to reduce costs or benefit from the relatively skilled labor force. However, as the level of cross border transactions increases, companies want to monitor and control their financials more intensively. A reliable accounting partner becomes a valuable asset.
