The BUP (Single Bank of Price Lists) is an online system used by media companies associated to CENP to register their Price Lists by upload. The measure, besides contributing remarkably to the media credibility, also favors the control instances of advertising agencies and public and private advertisers from all over Brazil.

Each media company has access only and exclusively to its own space to upload its list and its updates. The validity of the price lists, uploaded in PDF format, is defined by the media company, which also is solely responsible for its alteration.

The Price List registering system was created as a stimulus to the best commercial practices, also aiming at contributing to a correct performance of the commercial representatives. These should practice the same values expressed in the public Price list of each means of communication they represent, pursuant to  article 14 of Decree 57.690/66.
