Dynamic Purchasing System (DPS)
A Dynamic Purchasing System (DPS) is an electronic procurement arrangement under EU Directive 2014/24/EU that operates as a perpetually open framework: any qualifying supplier can join at any point during its validity period. The buyer runs mini-competitions among DPS members for each specific procurement need. DPS is increasingly used for commoditised IT services, supplies, and specialist defense services where new suppliers should not be locked out for the framework's full duration.
Etymology / origin
DPS was formalised in EU Directive 2014/24/EU Article 34 as a modern alternative to closed framework agreements. The 2014 reform aligned the mechanism with the electronic-procurement push that has reshaped EU public procurement during the past decade.
Where you encounter this term
Defense buyers using DPS include MOD Defence Equipment & Support (UK), several BAAINBw IT-services lines, and increasingly the Nordic defense agencies for commodity buys. DPS notices appear on TED and on national portals like Doffin and Find a Tender. The DPS-establishment notice describes the scope and validity period; subsequent mini-competition notices appear under the parent DPS.
Example — from the WULFRN database
WULFRN tracks 17 defense tenders explicitly using the "dynamic purchasing" phrase in their title across NATO. UK MOD and German BAAINBw lead DPS adoption for IT services and supplies. WULFRN's alert system can target DPS-establishment notices specifically so suppliers can join the DPS before the first mini-competition.

Frequently asked questions
What is a Dynamic Purchasing System (DPS)?
A DPS is an electronic procurement framework that any qualifying supplier can join at any time during its validity. The buyer runs mini-competitions among DPS members for each specific need rather than locking in a fixed roster of suppliers for the framework's full duration.
How is a DPS different from a framework agreement?
A framework agreement is closed: the suppliers selected at award time are the only suppliers for the framework's full duration (typically 4 years). A DPS is open: qualifying suppliers can apply to join at any point. Both mechanisms run mini-competitions for individual call-offs.
How do I join an existing Dynamic Purchasing System?
Locate the DPS-establishment notice on TED or the national portal, review the qualification criteria, and submit a Request to Participate (RTP) demonstrating your eligibility. The buyer must accept qualifying applicants within 10 working days. Once accepted, you receive every subsequent mini-competition invitation under the DPS.
