What is Ariba?

Ariba (SAP Business Network) connects buyers and suppliers. It lets you respond to sourcing events, receive orders, send invoices and manage your supplier information. See ariba.com for more. 

We use SAP Ariba for tender events and expressions of interest.

We run all tendering in Ariba. If you’re invited to a sourcing event, you’ll receive an email with a link to Ariba. Use it to create an SAP Business Network account (if needed), log in and follow the prompts to submit your response. 

To register interest in upcoming events, visit our Tenders and registrations of interest page. Tenders are by invitation only; registering interest doesn’t guarantee a tender invitation or that you will receive any work. 

For help responding to a tender event, see Responding to events in Ariba

To submit a general expression of interest, use the Supplier Introduction form

Registration in Ariba

Ariba Registration is sent to suppliers before we invite you to participate in a tender. We’ll send you a short form to collect standard business details and other information we will need if we trade with you. We can’t invite you to tender until you complete the registration form we send. Registration doesn’t guarantee that you will receive work from Western Power.  

Supplier accreditation 

If you’re successful and we award a contract, we’ll start supplier accreditation to add you to our purchasing systems. Supplier accreditation sets you up to trade with us through our procurement systems in SAP Ariba. You’ll use your Ariba account to submit and manage details such as insurances, business information and banking. 

Ordering and invoicing 

We use Ariba to issue orders and receive invoices via the SAP Business Network. You can log in to see invoice and remittance status in real time. 

To transact with us you’ll need, at minimum, a Standard Ariba account. It’s free to set up and use. See Transacting with Western Power for account options. 

For help viewing orders or loading invoices, see the Ordering and invoicing in Ariba guide. You can also access Ariba support
