Costs for Suppliers
There will be no further costs to you as a Webasto supplier when using SAP Ariba. However, you can choose whether to create a standard or enterprise account.
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.
- If you would like to upgrade your Standard account to an Enterprise account, you can do this by clicking “Upgrade” in your account and discussing/following up with Ariba®.
