General
Ariba is an online Network that supports collaboration between buyers and suppliers, including allowing suppliers to respond to sourcing events, receive orders and send invoices, and manage their supplier information. See the Using Ariba as a Western Power supplier page for more information.
Western Power’s purchase orders contain general terms and conditions. If the purchase order is issued under an existing contract between Western Power and the supplier, then the terms of that existing contract will apply. In these circumstances, the purchase order will include a reference to the contract number of that existing contract.
Where there is no existing contract between Western Power and the supplier, Western Power’s purchase order terms and conditions will apply.
See the Sustainable procurement page on our website for more information.
