The SISCOSERV is a system for controlling purchase and sale of services. It was created by the Federal Revenue of Brazil and the Ministry of Development, Industry and Foreign Trade, in which taxpayers resident in Brazil must inform all of their transactions of purchase and sale of services to residents abroad, under pain of heavy penalties for failure, delay or error in the records. CONEXO offers an information service, control and record of these operations, minimizing risks inherent the complexity of such operations.
