What percentage of their total volume per customer can suppliers be billed according to the Ariba Network supplier fees?

The correct choice regarding the percentage of their total volume per customer that suppliers can be billed according to the Ariba Network supplier fees is 0.155%. This fee structure is designed to enable suppliers to cover some costs associated with the services provided through the Ariba Network while ensuring that the fees are not prohibitively high.

Understanding this percentage is crucial for suppliers, as it directly affects their pricing strategies and profit margins. The fee allows suppliers to access the network's features, including procurement and invoicing tools, which facilitate smoother transactions and potentially increase their customer reach. Each supplier should assess this cost in the context of their overall business strategy and the benefits gained from participation in the network.
