A reverse auction is a type of online bidding event where sellers compete to offer the lowest price to win business from a buyer.
Unlike a traditional auction—where buyers bid higher to win—the roles are reversed. Reverse auctions are widely used in government procurement, manufacturing, IT services, and corporate sourcing to achieve cost savings and transparency.
A reverse auction is an online or live event where multiple sellers bid competitively to supply goods or services to a buyer.
The auction starts with a maximum acceptable price, and suppliers gradually lower their offers until the auction closes. The buyer then selects the bid that offers the best value, usually the lowest price meeting all criteria.
The buyer defines:
Product or service specifications
Quality standards and quantity
Delivery timelines and payment terms
Qualified suppliers are invited to participate. Invitations can be sent directly or via an e-procurement platform.
Parameters such as duration, minimum bid decrement, and evaluation criteria are configured on the auction platform.
Suppliers register, agree to terms, and ensure they meet eligibility requirements.
Sellers submit their bids in real-time. Each bid lowers the price or improves the terms to stay competitive.
Both buyer and sellers can see the ranking of bids (but not always competitors’ identities), encouraging healthy competition.
After the timer ends, the buyer reviews all bids against technical and commercial parameters.
The supplier with the most favorable offer (not always the lowest price) wins.
A final contract is then negotiated and executed.
Scenario:
A company wants to purchase 500 laptops for its employees.
Instead of asking for multiple quotations, it holds an online reverse auction.
Five IT suppliers are invited.
The bidding starts at ₹40,000 per laptop.
Over 30 minutes, vendors reduce their offers to outbid competitors.
The lowest valid bid is ₹35,700 with full warranty and delivery terms.
The company awards the order to that vendor—saving nearly 11%.
