The opportunity does exist. You may both receive profits on the accounts of a Serbian umbrella company and use the above accounts to pay for services provided to you by any other persons or companies. Say, you receive money from the Chinese X company for IT services rendered by you and at the same time make a service agreement with the Y Company from Germany. To minimize the transaction number, the money received on the umbrella company’s account for any services rendered by you to the X Company from China, shall be forthwith transferred to the Y Company’s account in Germany as a payment from you. The resulting difference goes to you, and Rent-a-Company in Serbia charges its interest for the services provided and takes care of document processing.
