Western Power uses the Procure-to-pay module to issue orders and receive invoices via the Ariba Network. This allows us to streamline catalogue maintenance and to consolidate manual commerce processes for us to reduce errors. We’re able to gain insight into our essential procurement processes, ensuring that waiting times for approval are minimal.
