While you are not required to register for a particular account type, in some cases we recommend that suppliers choose to transact on the Ariba Network with us using a fee-based Enterprise account due to the historical volume of their transactions, or to leverage certain functionalities. Please visit this page on the Ariba website for more information on the difference between the two accounts.

If you choose to subscribe for a fee-based Enterprise Ariba account, all costs associated with the account are the sole responsibility of your party. We do not cover any costs or fees attributed to you on Ariba Enterprise accounts and only require you to sign up for a free of charge Standard account. 

The Ariba Network is not provided by us. Your use of the Ariba Network is subject to Ariba's applicable terms of use and policies. You are responsible for all activities that occur under your Ariba Network account and access credentials, whether conducted by an employee or a third party. We are not responsible for any data shared on the platform. 

If you’re already using an Enterprise Ariba account with a buyer, we recommend that you continue using it. There's no direct way to change an Ariba subscrption (Enterprise account) to a Standard account. Suppliers who have already registered for a fee-based Enterprise account and are interested in downgrading to a free of charge Standard account should begin the downgrade process by opening a ticket with the Ariba Help Desk and creating a dispute case.

The project team is actively encouraging all suppliers to participate, with the aim of minimising manual effort from all parties. In the long term, suppliers who refuse to participate without a valid reason and when there are alternatives in the market may risk losing business with us. There are other streams of the project to automate other processes, but the majority of our supply base is expected to use the Ariba Network.
