How do I become a Thiess Supplier?

As a preference we select suppliers locally, nationally and then internationally. The group strategic sourcing team targets those categories of spend which have applicability to multiple business units and runs a robust evaluation process.  Corporate suppliers are selected based on our priorities and a view towards a long term relationship. Project suppliers tend to be selected on a fixed term basis for products or services with a specific or specialised local need.  To become a corporate supplier, please register your interest online. 

To provide products and services to an individual project, suppliers are encouraged to contact those projects directly.  However, both groups have access to the supplier database.

If we already provide services or products to Thiess should we still register?

The team has likely already categorised your offering and has entered this into our database.  It is not necessary for you to register again, however if your business range or other details have changed, it is a good idea to register and update us.

What should we do if we have an offer that Thiess simply must see?

Please send an e-mail to  describing the situation. This e-mail is reviewed daily and funnelled to the relevant category manager for assessment.

Must we be able to trade electronically to supply to Thiess?

Thiess is looking to electronically enable all suppliers who provide goods or services to one or more site. 

Do we need to supply our products or service to all Thiess to be considered?

No.  Thiess uses a combination of local and national suppliers.
