As part of our procurement upgrade, we have now transitioned to our new supplier management process through SAP Ariba Business Network (SAP Business Network or ‘SAP Ariba’).

This transition means that, as of 29 March 2023, our valued current and new suppliers are required to transact with us via the CSIRO Supplier Portal, hosted by SAP Ariba.

Hi, my name is Tom Munyard. I'm CSIRO's Chief Operating Officer.

We've transformed our CSIRO procurement and payment channels to improve the way we do business with our suppliers.

CSIRO is now well advanced with our business transformation to improve our purchasing processes and the way we work with our suppliers.

As part of this program we have implemented the CSIRO Supplier Portal hosted by the SAP Ariba business network.

Internally our CSIRO people refer to it as Guided Buying.
Our system upgrade to CSIRO Guided Buying underpins of range of major science saving benefits:
Firstly, clear steps for purchasing means more time for doing what our people do best, innovating.
Easy to follow guidance for accessing new and existing suppliers means
greater research collaboration, reporting, reliability and accuracy.
And Guided Buying means less mistakes and less support tickets.
For our vendors, our secure CSIRO supplier portal empowers you to:
manage your confidential information, including Banking and tax details with unique logins.
To receive CSIRO approved purchase orders for goods and services straight to your inbox.
And to submit online invoices for reconciliation against our purchase orders and receive payment all within the portal.
If you're getting started with CSIRO Guided Buying remember this:
there are no changes to our existing procurement guidelines
regarding simple medium or complex thresholds.
The dollar amounts remain the same and
Guided Buying monitors those thresholds with every purchase requisition, purchase order, or subsequent variation.
And we continue to offer eligible employees
the ability to complete purchases up to $5000 using an approved CSIRO credit card.
Of course, terms and conditions apply.
What are the benefits you can expect as suppliers?
Well firstly, increased operational efficiencies
with the ability to see the status of your purchase order and invoicing data updated regularly throughout the day.
Secondly, improved accuracy across purchase order, goods receipt and invoice reconciliation
all taking place within the system payment.
And thirdly, improved collaboration without compromising the need for speed
when it matters in a supplier's day-to-day work with us.
CSIRO Guided Buying hosted by SAP Ariba
means clear, efficient and consistent processes.

What does this means for our supplier network?

All new and existing suppliers

Through our new portal, suppliers will have the opportunity to manage their own data, to receive CSIRO purchase orders, goods receipt confirmations and submit invoices.

There is no charge to our suppliers to make this transition with us when using the SAP Ariba Business Network ‘Standard Account’. This platform caters to small, medium and large businesses.

Whether you’re a new supplier to CSIRO or have been working with us for a while, there are a few key points to ensure swift exchange of information.

Are you registered on the CSIRO Supplier Portal?

Yes, I am…

  • Please ensure you use the same login account when you receive your first purchase order. This is very important.

No, I am not...

  • If you haven't registered with us yet, at the time of your first purchase order, you will be asked to sign up for the standard free account, or use an existing SAP Ariba account that you may have with other buyers. This account will link you to the to the CSIRO Supplier Portal as well.

Purchase orders and invoicing

If you've worked with us in the past, your purchase orders and remittance advices will look a little different.

New purchase orders (after 29 March 2023)

New purchase orders from CSIRO will be issued an SAP Ariba purchase order number beginning with #4600xxxxxx

If you’re invoicing against a new purchase order starting with #4600xxxxxx, you will need to submit your invoice using your CSIRO Supplier Portal account only. We will not be able to receive invoices via email.

Existing open (legacy) purchase orders (prior to 28 March 2023)

Whilst initially intended for late April, the transfer of any existing purchase orders into the new system has been paused. This will help minimise disruptions during the busy end of the financial year period.

We will communicate directly with our relevant suppliers (and CSIRO requestors) in late July when the purchase order transfer will begin again. Thanks for your understanding.

How to invoice against an open (legacy) purchase order

If you are invoicing against legacy purchase orders starting with 4000xxxxx please contact our Payment Support Centre via

There is a high volume of queries and payment requests expected at this time. Your inbound email will enter our queue and be processed accordingly. If our team require any more information they will contact you directly.

Note: This only relates to CSIRO POs starting with the old #4000xxxxx. All new SAP Ariba invoice details should be entered within your CSIRO Supplier Portal on Ariba by locating your #4600xxxxxx purchase order and submitting.

Our contact with you about the CSIRO Supplier Portal

Below are the three primary SAP Ariba email and web addresses you can expect to receive correspondence from:

Please monitor your inbox and spam folders for the above email and web addresses so that any engagement, communication or procurement notifications from us can reach you.

Please note that completing the SAP Ariba registration does not guarantee the supplier any future procurement activities with CSIRO.


For further information to support you through this transition, please login to your CSIRO Supplier Portal account and access the helpful resources within the SAP Ariba dashboard. This includes trouble shooting tips and answers to frequently asked questions.

Suppliers can also contact our Payment Support Centre team via email or phone 1300 503 418. We understand this will be a period of change for existing suppliers and we thank you for your patience during this time of transition.

Short instructional videos are available on a range of topics to assist you in using the system.
