Payment platforms

At Westpac we have several payment platforms. It is important that you confirm which payment platform you will be using prior to providing goods and services to Westpac. Our WEAPS (Web Enabled Accounts Payable System) and Ebuy payment systems are the most frequently used. Further information regarding these payment systems are provided below.


If your Westpac contact advises you to use an alternate payment platform, please request further information from your Westpac contact.

Web Enabled Accounts Payable System (WEAPS)

If you are unable to supply all three pieces of information, only the requestor is absolutely necessary.

If the above information is not provided, this may result in delays to your payment as we will need to make enquiries on your behalf to find the correct Westpac Group contact.

Invoice Central will enter the invoice into our WEAPS payment system and direct your invoice to the correct business unit for payment.
