Transition from the CSIRO Supplier Portal

The CSIRO Supplier Portal, hosted by SAP Ariba, has been discontinued from Monday 25 March 2024.

CSIRO is reverting to a previously used procurement and payments system, supported by our Payments Support Centre.

Suppliers who transacted with CSIRO, using the SAP Ariba Business Network, may still see their transaction history, including the completed CSIRO Registration Questionnaire.

You will no longer be able to use the CSIRO Supplier Portal to:

  • submit your invoice details
  • see new purchase orders from CSIRO, appearing in your dashboard
  • edit/update your supplier information with us including your bank account, tax status, address, contact information.

From Monday 8 April 2024

CSIRO has completed the transition to a previous procurement and payments system.

If you have worked with CSIRO, in the past, your purchase order template and remittance advice may look a little different.

Purchase orders

New purchase orders from 8 April will have a number sequence commencing with: 4000xxxxx.

In some instances, your CSIRO buyer/purchaser are not required to generate a purchase order and can purchase items using their CSIRO corporate credit card or providing an alternative purchase reference. In all procurement activities, the Commonwealth Procurement Rules apply.

Purchase orders numbers previously issued by SAP Ariba (46000xxxxx) and our legacy (4000xxxxx) systems will be retained to assist your bookkeeping practices.

How to submit your invoices to CSIRO

Your CSIRO buyer/purchaser is your key point of contact.

While you may see previous CSIRO purchase orders in the SAP Ariba Business Network, you will no longer be able to create invoice details against those purchase orders in the SAP Ariba system.

Your PDF invoice should be emailed directly to your CSIRO buyer/purchaser who will review and submit the invoice for processing by the CSIRO Payment Support Centre.

This means you are not required to separately email invoices to In fact, doing so risks duplication and delays.

Please ensure you include the correct reference on your purchase order before submitting. This may include the Purchase Order number, or if under A$50,000 (inclusive of GST) an alternative reference supplied by the CSIRO buyer/purchaser at the time of request.
