GeM bid vs reverse auction: what's the difference?

5 min read · Last reviewed 14 August 2026

On GeM, a bid is a sealed competitive event in which sellers submit technical and financial offers that are opened and evaluated at a fixed time, while a reverse auction is a live event in which technically qualified sellers compete by successively lowering their quoted price within a set window.

Both are competitive and both end in an award, but they demand different preparation. A bid is decided by what you submitted; a reverse auction is decided by what you are willing to do while it is running.

How a bid works

The buyer publishes requirements, specifications and eligibility conditions with a closing date. Sellers submit a technical bid and a financial bid. At opening, technical bids are evaluated against the stated criteria, financial bids of qualified sellers are opened, and the award follows the evaluation method — usually lowest price among the qualified, with MSE purchase preference and Make in India preference applied.

Everything that decides the outcome is fixed before the closing time. Your leverage is entirely in preparation: qualifying cleanly, meeting specifications exactly, and pricing well once.

How a reverse auction works

A reverse auction adds a live phase. Sellers who qualify enter an auction window and compete by lowering their price, seeing their relative position as it runs. The price falls until the window closes, and the lowest standing offer wins.

The dynamic is the point: prices in a reverse auction typically land below what the same sellers would have quoted in a sealed bid, which is why buyers use them. For a seller, that means the auction is where margin is lost, and it is lost in minutes.

Setting a floor before you enter

The discipline that separates sellers who do well in reverse auctions from those who regret them is a floor price computed before the auction opens — and honoured during it.

1. Compute your true landed cost, including delivery to the specified location, taxes as applicable, and the cost of meeting the delivery timeline.
2. Add the cost of the obligations that come with the order — performance security, warranty, any support period.
3. Set the minimum acceptable margin, and write the resulting floor down before the auction.
4. During the auction, stop at the floor. A won order below cost is worse than a lost auction, and the delivery obligations are enforceable.

Which one you face

The buyer chooses the mode. You can prepare for both the same way — qualify cleanly and know your numbers — but if the event is an auction, the number you need is a floor, not a quote.

Key takeaways

• A bid is decided by what you submitted; a reverse auction by what you do live.
• Reverse auctions systematically clear below sealed-bid prices — that is their purpose.
• Compute a floor price before entering, including delivery, taxes and obligations.
• Stop at the floor: a below-cost win is still a binding contract.
• Technical qualification precedes the auction, so eligibility work is unchanged.

Frequently asked questions

What is a reverse auction on GeM?

A reverse auction on GeM is a live competitive event in which technically qualified sellers lower their quoted prices within a set time window, with the lowest standing offer at close winning the order. It differs from a bid, where sealed offers are submitted in advance and opened at a fixed time.

What is the difference between a GeM bid and a reverse auction?

In a GeM bid, sellers submit sealed technical and financial offers that are evaluated after the closing time, and the outcome depends entirely on what was submitted. In a reverse auction, qualified sellers compete live by successively lowering price, so the outcome depends on decisions made during the auction window.

How do I decide my price for a GeM reverse auction?

Compute a floor price before the auction opens: true landed cost including delivery and taxes, plus the cost of contractual obligations such as performance security and warranty, plus a minimum acceptable margin. Enter the auction with that number written down and stop bidding when you reach it.

Are MSE benefits available in a GeM reverse auction?

Micro and small enterprise benefits under the Public Procurement Policy for MSEs, 2012 — including exemption from tender fee and EMD and purchase preference — apply to public procurement generally, subject to what the specific tender or event provides.
