The solution according to AribaPay

• AribaPay via the Discover Network will enable a buyer to initiate an electronic payment from its bank account, which Discover will then direct to the supplier’s bank account.
• Discover, as the enabling platform, will handle all settlement functions and will hold banking information. Buyers don’t have to mess with getting and keeping bank account information for suppliers
• The only requirement is for both buyers and suppliers to be on the Ariba network
• Once a supplier has an AribaPay “account” established, she or he can use it to accept payment from any AribaPay buyer. In that way, one can think of AribaPay as sort of a PayPal for B2B payments.
