E-informing can be used for the easy job of exchanging purchasing information between buyers, suppliers and end-users. Traditional contact methods are more complex processes. Using the Internet technologies such as e-mail, the method of gathering a database of supplier information can be made much simpler than by using traditional contact methods.
Perhaps most significantly, these databases are useful in the future for generating action in a reverse auction. With the help of these databases an enterprise can inform suppliers of approaching auctions. It provides suppliers the time to build a tender based on these databases.
