The Buyers are unaware this is taking place.
Companies such as UPS and others have no idea that Ariba is forcing Sellers to pay Thousands of dollars a year for services they do not need just to get paid for their services. There is a way around it all. Sellers make sure you let your customers know that Ariba is trying to force this. Ariba will give UPS and others a phone number to call to setup an account with Ariba for zero cost. This way you can get paid and not get swindled by Ariba.
