General
Ariba (SAP Business Network) connects buyers and suppliers. We use it for sourcing events, ordering, invoicing and supplier information. See Using Ariba as a Western Power supplier.
Our purchase orders include general terms and conditions. If an order is issued under an existing contract, the terms of that contract applies and the purchase order will reference the contract number. Where there’s no contract, our purchase order terms and conditions apply.
