PTA ZSN Supplier Portal

The go-to place for supplying to the PTA

Welcome to PTA ZSN Supplier Portal

The PTA ZSN Supplier Portal is the single system for suppliers to manage all details in one place.

It's important you can access the portal and able to navigate the system so you can respond to requests for quote and open tenders.

About the portal

The PTA Zycus Supplier Network (ZSN) provides a more efficient way to supply to the PTA. Through the portal, suppliers have:

  • Autonomy over company details
  • Improved data security 
  • A reduction in manual forms, phone calls and emails with the PTA

Two important steps to make the most of the portal

There are two important steps you need to do to ensure you are set up to start using the portal:

  1. Add @zycus as a Safe Sender in your email
  2. Add users to your Company Profile

Step 1 - Add @zycus as a Safe Sender in your email

Emails from the portal (such as the invitation to respond to a procurement request) are sent by the system vendor, Zycus. These are important emails which may get caught in your email's spam filter. To avoid this, you'll need to add @zycus as a Safe Sender in your email client.


If you do not do this, you may miss out on important emails from our supplier portal, such as the opportunity to quote.


How to add an email to Safe Sender list in Outlook

  1. From the Home ribbon, open Junk Email Options settings
  2. Under Safe Senders and domains, select Add and enter
  3. Select Save


Step 2 - Current suppliers: Add users to your Company Profile

Current suppliers to the PTA will already have an account for the ZSN Supplier Portal.

If there are multiple people in your company who need access to the portal (e.g. to respond to different quote requests) you will want to add them to your company profile.

Follow the How to add users to your Company Profile guide so that the correct people can access the portal and respond to requests.

Unsure of your login?
