Commercials Manager has been specifically designed for the management of radio advertising campaigns. This software package is especially useful for the insertion of advertising spots in blocks, the calculation of campaign costs, monthly or longer period sales reports, price estimates etc. The module is the “right hand” of the sales department, because it prepares the offers for the customers, as well as the reports concerning the media plan, cash-flow, monthly income or the advertising grid for certain time intervals. Once the advertising campaign has been programmed (regardless of its complexity), the broadcasting is guaranteed, because the software automatically selects the advertisements that are to be broadcasted every day. Special features have been implemented for radio networks that allow traffic-manager to select one or more cities for uniform commercials scheduling, advertising calculate hourly load times taking into account both local and national advertising, generating of complete reports on any desired aspect regarding the management of advertising campaigns.
