Procurement Procedures

Electronic Auction

Iterative electronic procedure for price determination where bidders can adjust their offers in real time.

What is an Electronic Auction?

An electronic auction (also: e-auction, reverse auction) is an iterative electronic procedure in public procurement where bidders can adjust their prices or other quantifiable criteria in real time.

Legal Framework

  • Section 25 VgV: Electronic auctions above EU thresholds
  • Art. 35 Directive 2014/24/EU: EU directive on electronic auctions

How It Works

  1. Regular tender procedure
  2. Initial evaluation of submitted bids
  3. Invitation to all eligible bidders for the e-auction
  4. Auction rounds: bidders can lower prices in real time
  5. Award to the most economically advantageous offer

Conditions

  • Must be announced in the contract notice
  • Only for quantifiable criteria (price, quantities, times)
  • Not allowed for intellectual services (architecture, consulting)
  • Bidders see their rank but not competitors' identities

Benefits

  • Price transparency through competitive pressure
  • Efficiency: price determination in hours
  • Typical savings of 5–15% compared to static offers
