Reverse Auction (RA)

A Reverse Auction (RA) is a live online event where technically qualified bidders compete for a contract by progressively lowering their quoted price, and the lowest bidder at the close wins.

What is Reverse Auction (RA)?

In a normal auction, buyers bid prices up. In a reverse auction the direction flips: the procuring entity is buying, so sellers bid the price down. After bidders clear the technical stage, all of them enter an online auction room at a scheduled time. The starting price is usually the L1 from the initial sealed bid. Each bidder can see the current lowest price (the L1), but not who quoted it, and can keep cutting their own price in small steps. The auction typically runs for one to three hours, with auto-extensions when bids arrive in the last few minutes, so the clock does not simply run out on an active contest. When no fresh bid comes in for a defined period, the auction closes and the last lowest bidder is declared the winner. This format is common on the Government e-Marketplace (gem) and on PSU portals, mainly for commodity items where specifications are standard.

Why RA matters for bidders

Reverse auctions reward sharp costing and nerve, not paperwork. Because the live contest typically drives the final price 5 to 15 percent below the sealed-bid L1, you must know your true floor before you enter the room. Build that floor from a clean boq so you do not bid below cost in the heat of the auction. Understanding the l1-l2 math behind these wins helps you decide when to keep cutting and when to stop. Unlike a qcbs tender where quality scores soften pure price, an RA is price-only once you qualify.

Example

A central government department needs 500 desktop computers on GeM. Twelve sellers clear the technical evaluation and join the reverse auction at 11 AM. The starting L1 from the sealed bids is Rs 32 lakh. Over the next ninety minutes, sellers undercut each other in small steps, watching the anonymised lowest price drop. A last-minute bid at 12:25 PM triggers a short auto-extension. When the dust settles, the winning seller closes at Rs 28.5 lakh, roughly 11 percent below the opening L1.

Frequently Asked Questions

When is a Reverse Auction used in India?

RAs are used mainly on GeM for commodity procurement and by PSUs for high-volume, specification-standard items such as fuel, chemicals, and raw materials. On GeM, a bid or reverse auction applies to purchases above Rs 5 lakh. They suit items where one product is interchangeable with another, so price is the deciding factor.

Can I see who I am bidding against?

No. During the auction you can see the current lowest price, but the identity of the bidder behind it is hidden. You compete against an anonymised L1 number, not against named rivals. This keeps the focus on price rather than on reputation or relationships.

How much can a Reverse Auction lower the price?

In practice, reverse auctions drive the final price about 5 to 15 percent below the initial sealed-bid L1. The exact drop depends on how many qualified bidders join and how aggressively they compete. Commoditised categories like computers, printers, furniture, and stationery tend to see the steepest reductions.

What is the auto-extension feature?

If a new lower bid comes in during the closing minutes, the auction clock is extended by a short period. This stops a bidder from sniping the lowest price at the very last second with no chance for others to respond. The auction only closes when a defined quiet window passes with no fresh bids.

Is technical qualification needed before the auction?

Yes. Technical qualification is completed before the live auction begins, so only compliant bidders enter the room. The auction itself is a price-only contest. If your bid does not meet the technical and eligibility criteria, you never reach the auction stage, no matter how low your price would have been.
