Our new approach to purchasing


Our new approach to purchasing

At Z, we’re continuing on our journey to leverage technology and simplify our operations to support solving what matters for our customers, shareholders and stakeholders. As part of this journey, on 1 November we implemented a new enterprise resource planning system – this is the core computer system we use to run our business.

Along with the upgrade, we’ll be streamlining our process for paying your invoices. This will mean there are changes to the detail we need on your invoice and how you send invoices to us.

  • From now on we’ll provide you with a purchase order for goods and services we purchase from you.  If you don’t receive a purchase order, please request one from your Z contact before supplying goods or undertaking work for us. 
  • Please include the purchase order number, along with your GST number and bank account number on all invoices. Each purchase order will require a separate invoice.
  • Email invoices to in pdf format, with one invoice per pdf. Please attach only invoices to the email – any other supporting attachments should be sent to the contact person on the purchase order.

You may also notice some changes to the way we purchase goods and services at Z.  This includes more focus on building strong relationships with our suppliers and ensuring greater emphasis on our Four Stands when we purchase goods.    

We remain committed to getting the best results from our spending through fair and effective partnerships with our suppliers and service providers.  If you have any questions please get in touch with your Z contact or drop us a line at
