Welcome to PTA ZSN Supplier Portal
The PTA’s Zycus Supplier Network (ZSN) Supplier Portal changes the way that the PTA interacts with suppliers. By moving towards a more streamlined, digital portal, suppliers will initially have autonomy over their company and bank account details, have improved security of their data, reducing manual forms, phone calls and emails with the PTA. Further functionality will be introduced throughout 2022.
Go to Tenders (pta.wa.gov.au) for details on the PTA tender close down period.
