Reverse auctions: Definition & important aspects for buyers
.jpeg)
Reverse auctions in a nutshell:
A reverse auction is a digital bidding process in which several suppliers adjust their prices for defined products or services downwards in real time in order to be awarded the contract. For procurement, this tool enables transparent pricing and significant cost savings through direct price competition.
Example: An automobile manufacturer conducts a 60-minute reverse auction for metal components in which five qualified suppliers bid down from a starting price of 250,000 euros to a final price of 198,000 euros through 23 bids, which corresponds to a saving of 20.8%.

Introduction to reverse auctions
What are reverse auctions?
Reverse auctions, also known as reverse auctions, are an electronic procurement tool in which the roles of buyer and seller are reversed compared to traditional auctions. Here, suppliers compete in real time to win an order by successively lowering their prices. The aim is to achieve the best possible price for the purchasing company through competition between suppliers and thus realize cost savings.
Core elements of reverse auctions
Significance for purchasing
Reverse auctions are becoming increasingly important in modern procurement, as they offer an efficient way of reducing procurement costs and speeding up the award process. They enable buyers to obtain a large number of offers in a short space of time and benefit from the competitive dynamics. They also promote market transparency and strengthen the purchasing department's position in price negotiations.
Implementation of a reverse auction
A reverse auction enables purchasing to achieve the best conditions through direct competition between suppliers. The requirements are precisely defined and suppliers undercut each other in real time to win the contract.
Practical example
Situation: A company needs 5,000 units of a standard component for production. The specifications and quality standards are clearly defined:
1. preparation: The buyer identifies six potential suppliers and sends them an invitation to participate in the reverse auction with all relevant information and requirements.
2. start of the auction: The auction begins at 10:00 a.m. with a starting price of € 10 per component.
3rd bidding round: - Supplier A bids €9.80- Supplier B bids €9.50- Supplier C bids €9.40
The suppliers observe the bids of the competition and adjust their offers:- Supplier A lowers to € 9.30- Supplier B lowers to € 9.20- Supplier D enters at € 9.15
4th closing: After several rounds, the auction ends at 10:30 am. The lowest bid comes from Supplier E with € 9.00 per component.
Result: The reverse auction reduces the price per component from the original €10 to €9. The company thus saves a total of €5,000 (€1 saving × 5,000 components).
