Account Details

  • The Standard Account is a free account on the Ariba® Network that allows users to process orders with their business partners via interactive e-mail. This means that suppliers can access the Ariba® Network through this interactive e-mail, allowing you to send order confirmations directly and easily. Therefore a standard account is recommended for suppliers who have a total of less than 75 documents from all business relationships per year. An Enterprise Account is recommended for suppliers who have a total number of more than 75 documents.
