GeM reverse auction strategy: set your floor price before it starts
The short answer
A GeM reverse auction is a timed online round, at least 24 hours long, in which qualified sellers undercut the prevailing lowest price in fixed decrements. The strategy is settled before it opens: work out your landed cost, the lowest price you will accept and who approves it, then bid in steps and stop at that floor.
Key takeaways
- In bid to RA, the sealed L1 price becomes the reference price, so quote the sealed bid as if no auction will follow.
- Every new bid must be at least one decrement below the prevailing lowest bid, and a lower bid in the last 15 minutes extends the auction by 15 more.
- Build the floor from landed cost, GST, contract terms and the minimum contribution you need, and get it approved before the RA opens.
- After the auction, MSE and Make in India preference, price justification and the price breakup can still change who supplies what.
Bid to RA or direct RA: which one are you in?
GeM runs reverse auctions two ways. In bid to RA, you submit technical and financial bids first; the buyer evaluates the technical side, and the auction then runs among qualified sellers under the rule the buyer picked when it created the bid. In a direct RA, which GeM announced as a "two step" process, there is no sealed price round: you make a technical offering, and after technical evaluation all qualified sellers are invited to the financial round.
In bid to RA, your sealed price already shapes the auction. GeM's seller FAQs say the L1 price of the bid is set as the reference price for the RA. Whoever was lowest in the sealed round decides where the auction starts, and everyone else has to beat that figure from the first move.
So quote the sealed bid as if no auction will follow, because sometimes none does, and sometimes you will not want to bid in it. Under the goods manual's tender cum reverse auction procedure, a bidder who stays out of the auction keeps its financial bid price as its valid offer, and its rank is set by the lower of the two prices. A careless sealed price can win you an order you never meant to take.
Who gets invited to a GeM reverse auction?
The two qualification rules, 50% elimination and H1 elimination, are set out in our GeM tenders explainer. For strategy, the finer print matters more:
- A minimum field. GeM's FAQs say offers of at least 3 sellers and 2 OEMs are kept without elimination.
- Split bids. If the buyer will divide the order among N sellers, at least N sellers go to the auction, and under H1 elimination the highest bidder stays in if it falls within those N.
- The MSE band only counts against a non-MSE L1. If L1 is itself an MSE, the 15% band brings no extra MSEs into the auction, and under H1 elimination the highest bidder is dropped whatever its MSE status. Make in India and its 20% band work the same way.
- A second OEM. If only one OEM's products would be left after elimination, GeM adds sellers until another OEM is in, where one is available.
Before the auction, work out who is likely to be in it with you. If you are an MSE sitting 10% above a non-MSE L1, you may get two chances: the auction itself, and a price match afterwards. That changes how hard you need to push during the round.
Start price and decrement: how each step works
GeM's general terms say the start or reference price and the step value of decrement are shown to bidders when the auction starts. Each new bid has to be one or more whole steps below the prevailing lowest bid. During the round you can see four things: the start price, the decrement value, the prevailing lowest bid and your own last bid. Competitor names are not on that list.
The goods manual, which sets defaults for reverse auctions on other government portals, suggests a decrement of 0.5% of the start price where the buyer sets none. On a ₹40 lakh start price, that is ₹20,000 a step. Whatever the size, count your steps in advance. The distance from the start price to your floor, divided by the decrement, is the number of moves you have.
| Rule | What GeM says | What it means for you |
|---|---|---|
| Reference price | In bid to RA, the L1 price of the bid | The sealed L1 is your ceiling |
| Decrement | A fixed step shown at the start; bid one or more steps below the lowest | Your floor converts into a number of steps |
| What you see | Start price, decrement, prevailing lowest bid, your last bid | You bid against a price, not a name |
| Duration | At least 24 hours | Plan who is on duty when it ends |
| Extensions | 15 more minutes after any lower bid in the last 15 minutes, with no limit on the number | There is no last-second win |
| Validity | Bid to RA offers stay valid for 30 days from the RA start | Your final price must hold for a month |
| Disruption | Restart from the last recorded lowest price; earlier bids stay binding | Every bid you place counts |
How to set your floor price before a GeM reverse auction
Your floor is the lowest landed price at which you would still rather win than lose. Set it in a meeting before the auction, write it down, and have the person who can approve it sign it. This build-up works for most goods:
- Direct cost per unit for this exact specification: material, conversion, packing and testing. Not your catalog average.
- Delivery to every consignee: freight, insurance, unloading and any installation. GeM offer prices are all inclusive of taxes, duties, transport and loading-unloading charges.
- GST at the applicable rate, because the auction price is a landed, tax-inclusive figure.
- The cost of the contract terms: performance security of up to 5% of the contract value, held until two months after warranty obligations end, any GeM transaction charge that applies, the payment cycle, warranty service and exposure to liquidated damages.
- The minimum contribution you need over direct cost. On idle capacity it can be thin; for a plant running full, it cannot.
- Add it up. Then round to a figure you can actually reach in whole steps from the reference price.
Write down a target as well: the price you expect to win at, drawn from past results in the category. Our guide to tender results shows how to build that history. Target and floor are different numbers. A lot of bad orders come from treating the target as the floor once the auction gets heated.
How to bid during a GeM reverse auction
- Staff it. You need the person entering bids, the person who approved the floor and someone watching the clock. In a 24 hour window the real action usually comes near the end, so plan who is on duty then.
- Move one step at a time unless you have a reason to jump. A big jump signals urgency and gives away margin nobody asked you for.
- Ignore the urge to snipe. A lower bid in the final 15 minutes adds another 15, and the extensions have no cap. Late bids only restart the clock.
- Watch the pace. Quick single steps usually mean two sellers trading blows; a long pause may mean someone has reached its floor.
- Stop at the floor. Once the prevailing lowest bid passes it, stop. Your last valid bid stays binding, and a split award or preference band may still bring you some quantity.
- Keep a backup connection. GeM's terms say neither GeM nor the buyer is liable for interrupted access, whatever the cause.
What happens after the reverse auction closes?
- Preference rules apply. GeM's terms say the award follows the MSE and Make in India orders, so an eligible MSE or local supplier within the band can be offered quantity at the L1 price. See MSE purchase preference.
- Price breakup. The winner must give a complete breakup of the quoted price in the required format before the award.
- Price justification. If the final price looks unworkable, the buyer can ask for a justification, and GeM's FAQs allow 48 hours to answer. See abnormally low bids.
- Negotiation. The goods manual says there shall be no negotiation once an e-reverse auction closes. GeM's buyer FAQs separately describe an L1 negotiation feature at financial evaluation, with up to five requests and 72 hours to respond each time, so read your bid terms.
- Performance security. Where the bid asks for it, it is due within 15 days of the award on GeM.
If you lost, save the auction result. A record of how low each seller went with this buyer is the most honest pricing data you will get. Our explainer on the L1 bidder covers how ties and split quantities are settled after the ranking.
Illustrative example: hospital beds for a Raipur hospital
This example is invented. A central government hospital in Raipur runs a bid to RA for 120 manual hospital beds, delivered and installed. A Ludhiana bed maker is L2 in the sealed round. The sealed L1 price of ₹38,40,000 becomes the reference price, with a decrement of ₹20,000.
| Floor build-up for 120 beds | Amount |
|---|---|
| Material, fabrication, finishing and testing | ₹25,80,000 |
| Freight from Ludhiana to Raipur, unloading and installation | ₹1,45,000 |
| Performance security, payment cycle and warranty cost | ₹70,000 |
| Minimum contribution the owner will accept | ₹2,20,000 |
| Subtotal before GST | ₹30,15,000 |
| GST at 18% | ₹5,42,700 |
| Floor, landed and GST included | ₹35,57,700 |
From ₹38,40,000, fourteen steps of ₹20,000 reach ₹35,60,000, the last step above the floor. The team agrees to bid one step at a time and stop at ₹35,60,000, and the managing director, not the sales manager, approves any change before the auction opens.
The lowest bid stalls at ₹35,80,000. The Ludhiana firm bids ₹35,60,000 with 10 minutes left, the clock extends by 15 minutes, and nobody answers. It wins at its floor, with the contribution it planned. Had a rival gone to ₹35,40,000, it would have stopped and kept its margin for the next tender.
How AI tools help before a reverse auction, and what you decide
Most of the floor price work happens in the bid document: consignees, delivery period, performance security, warranty, split ratio, preference clauses and the ATC. TenderGenie reads the bid pack and brings those clauses out with a reference to the source page, so costing starts from the actual terms. Competitor Intelligence adds award history and pricing signals from available award records, which helps you set a realistic target.
TenderGenie does not bid in the auction and cannot tell you what a rival will do. The floor, the target, the approver and the moment to stop belong to your team. Settle them in the bid/no-bid review, before the clock starts.
Questions and answers
What is the start price in GeM reverse auction?
In bid to RA, GeM's seller FAQs say the L1 price from the sealed bid is set as the reference price for the auction. GeM's general terms add that the start or reference price and the decrement step are shown to bidders when the auction begins. Every new bid must then be at least one decrement below the prevailing lowest bid.
How long does a GeM reverse auction last?
GeM's buyer FAQs set a minimum RA duration of 24 hours. The end time is not fixed, though. Whenever a lower bid arrives in the last 15 minutes, the auction extends by another 15 minutes, and GeM's seller FAQs say there is no limit on the number of extensions. Bids placed after the final end time are not recorded.
What is decrement in reverse auction?
The decrement is the fixed amount by which each new bid must fall below the prevailing lowest bid. On GeM, it is shown when the auction starts, and you can bid one or several decrements lower at a time. For reverse auctions on other government portals, the goods manual suggests 0.5% of the start price where the buyer does not set a figure.
What is a good reverse auction strategy?
Decide your floor price before the auction from landed cost, GST, contract terms and the minimum margin you need, and get it approved in advance. Set a separate target from past results. During the auction, bid one step at a time, ignore last-minute sniping because the clock extends, and stop once the lowest bid passes your floor.
What happens if I do not bid in the reverse auction?
Under the goods manual's tender cum reverse auction procedure, your financial bid price stays as your valid offer, and your rank uses the lower of your auction bid and your financial bid. On GeM, bid to RA offers stay valid for 30 days from the auction start, so assume your sealed price can still be accepted.
Can the buyer negotiate after a GeM reverse auction?
The goods manual says there shall be no negotiation once an e-reverse auction is closed. GeM also has a separate L1 negotiation feature at the financial evaluation stage, allowing up to five requests with 72 hours for the seller to respond to each. Check the bid terms, and price any revised offer against the same floor you set before the auction.
Can an MSE get the order without being L1 in a GeM reverse auction?
Yes, for part of the quantity. If L1 is not an MSE, eligible MSEs within 15% of the L1 price can be offered quantity if they match it, and GeM lets the buyer split such a bid among up to five MSE sellers. Make in India preference works in a similar way, with a 20% band for eligible local suppliers.
