Dynamic Purchasing Systems (SDA) are electronic acquisition processes for goods and services whose characteristics are generally available on the market and respond to the needs of a contracting authority. 

An SDA is open for its entire duration to any economic operator that meets the qualification criteria.

How they work

Intercent-ER's Dynamic Purchasing Systems are divided into the following phases:

  1. Intercent-ER establishes an SDA, publishing a qualification call;
  2. the interested economic operators request admission to the SDA;
  3. Intercent-ER admits the eligible economic operators to the SDA;
  4. Intercent-ER invites all the admitted economic operators to submit offers for each specific tender;
  5. Intercent-ER awards the contract after a competitive dialogue.
