Welcome to the Purchasing page

The Purchasing department supports the University of Twente in the efficient, lawful, and effective procurement of goods and services.
We ensure compliance with laws and regulations, the purchasing policy, and internal procedures.
Together, we aim for transparent agreements with suppliers, an optimal price–quality ratio, and well-managed contracts.
