Your Supplier Advocate

Your voice in The Westpac Group, helping you do business with us.

Delivering on our service promise

Westpac’s vision is “to be one of the world’s great service companies, helping our customers, communities and people to prosper and grow”.


In delivering on Westpac’s strategy, the Supplier Advocate recognises the part that our suppliers play in the community. The Supplier Advocate is the voice of suppliers within Westpac for:
 

  • Registering interest in supplying to Westpac,
  • On boarding new suppliers,
  • Paying valid invoices  within 30 days,
  • Queries or complaints, and
  • Fulfilling Westpac’s payment reporting obligations.


A key responsibility of the Supplier Advocate is to ensure Westpac meets its commitments under the Australian Supplier Payment Code, to which Westpac became a signatory in 2017.
