A reverse auction is the only part of a [GeM](https://gem.gov.in/) bid where the platform actively tries to make you poorer. Everything before it rewards preparation. This part rewards nerve, and punishes the lack of it. I’ve watched sellers do clean, disciplined work for three weeks, qualify technically, and then throw away their margin in the last ninety seconds — because someone undercut them by a few rupees and they couldn’t stand to lose. So let me go deeper than the [L1 bidding explained](/blog/l1-bidding-explained/) post did. Not what L1 means — you know that. How the auction itself is wired, where the trap is, and how to walk out of it with a contract worth having. ## The auction only starts after you’ve qualified A reverse auction doesn’t happen on every bid, and it never happens first. It’s a tool the buyer chooses to switch on, usually for goods and standard services where price is the deciding factor and the field is large enough to create real competition. The sequence is fixed. Bids open, the technical evaluation runs, and only the technically qualified sellers are admitted to the auction. If your documents were short or your offered item missed a specification clause, you’re not in the room, no matter how aggressive your price was going to be. This matters because the whole arc of [how tenders are evaluated and awarded](/blog/how-tenders-are-evaluated-and-awarded/) sits upstream of the auction. The auction is the last gate, not the first. (If you’re still getting comfortable with the earlier gates, the [GeM bidding process](/blog/gem-bidding-process-explained/) walkthrough covers them end to end.) The buyer then sets the auction up with a few parameters that decide everything about how the next thirty or sixty minutes will feel. ## Four numbers and one rule Understand these before you ever join an auction: - **Start price.** The ceiling. On GeM the auction usually starts from the lowest evaluated price already on the table — the L1 from the sealed financial bids. That becomes the figure everyone is trying to beat. You can’t bid above it. - **Decrement value.** The buyer fixes the minimum step you must move by. If the decrement is a fixed rupee value or a percentage of the start price, you can’t shave one rupee off the current low. You must drop by at least that step. - **The live decremental window.** Once it opens, the clock runs. Sellers revise their price downward, each new bid has to beat the standing lowest by at least the decrement, and the current L1 is shown live. You watch the number fall in real time and decide, again and again, whether to chase it. - **Automatic time extension.** If a bid lands in the final minutes of the window, the clock extends — often by a set few minutes — to give others a chance to respond. ### Why the decrement matters The decrement is deliberate. Small decrements let the price drift down gently over many rounds. Large decrements force big, painful jumps and end the auction faster. Read it before you start, because a large decrement changes your floor maths completely. ### Why the time extension catches first-timers A “two-minute warning” is not a deadline. The auction doesn’t end until a full extension period passes with nobody bidding. So the idea of sniping at the last second — winning before anyone reacts — doesn’t work here. Every late bid simply resets the timer. Plan for an auction that ends when the bidding genuinely stops, not when the original clock says. ## You see the price. You don’t see the people. This is where the psychology lives. On GeM you see the current lowest price and your own rank. You don’t see who is behind the other bids, and you don’t see how many sellers are actively willing to keep going. That asymmetry is engineered to unsettle you. When the number drops below yours, you don’t know if it was a serious competitor with a real cost advantage or a desperate seller about to win a loss. You only know you’re no longer L1. The platform is counting on that uncertainty to pull one more decrement out of you, then another. The buyer benefits from every seller assuming the others can go lower. ## Set your floor price the day before, in a quiet room The single most important number in the entire auction is one you calculate the day before, with a spreadsheet and no adrenaline. Your floor. The lowest price at which this contract is still worth doing. It’s not your cost. It’s your cost plus everything the contract does to your cash: - Your all-in delivery cost, including freight, taxes you can’t pass on, and any wastage. - The [EMD and the ePBG](/blog/emd-epbg-mii-mse-tender-terms/), which lock up capital or a bank limit for the full contract duration. That money isn’t earning for you while it sits there. - The payment cycle. If this buyer pays in ninety days and you pay your suppliers in thirty, you’re financing the gap. Price that financing in. (Government buyers have [payment-timeline rules for MSMEs](/blog/government-tender-payment-rules-msme-45-day/) — know where you stand before you assume the worst, or the best.) - A real margin, not a token one. A contract at break-even is a contract that consumes capacity you could have spent on a better one. Write the floor down. Then treat it as a wall, not a suggestion. The entire purpose of writing it down beforehand is that the calm version of you is smarter than the version watching the number drop at minute forty. Do the floor maths early The floor only works if you saw the tender days before auction day, not hours.

One more decrement. The problem is the decrement is fixed, so “one more” might be a meaningful chunk of your margin, not a rupee. Sellers who win this way often discover the win at the moment they realise they’ve priced below their floor and can’t withdraw cleanly. Then there’s ignoring the cash impact. A price that looks profitable on the P&L can still drown you on cash. The ePBG ties up a bank limit you might need for the next three tenders. A long payment cycle means you fund the whole job out of pocket for months. The short version: a contract you can’t cash-flow isn’t a win, it’s a slow loss with a certificate attached. Treating the time extension as a deadline is the third. You bid hard near the original close because you think it’s about to end, then watch the clock reset and a fresh round of undercutting begin — after you’ve already spent your buffer. And finally, joining auctions you were never going to win profitably. Some auctions are won at prices only a seller with a structural cost advantage can sustain. An OEM with their own manufacturing, or a player clearing inventory, will have a floor below yours. There’s no tactic that beats a genuinely lower cost base. MistakeWhat it actually costs One more decrement to retake L1A real slice of margin, not a rupee Pricing without the ePBG cash hitA bank limit frozen for the contract term Ignoring a long payment cycleMonths of self-funded working capital Treating the timer as a hard closeYour buffer spent before the real ending ## Sometimes the win is to not win This is the discipline almost nobody talks about, and it’s the one that keeps you in business. Sometimes the right move in a reverse auction is to hold at your floor, let it pass below you, and lose on purpose. If the price has dropped under your floor and shows no sign of stopping, the seller who keeps bidding is volunteering for a loss. Let them have it. You’re not failing to win — you’re refusing to fund someone else’s order at your own expense. The seller who can sit still while the number falls past their floor, and feel nothing, is the seller who’s around next quarter to win the auction that actually makes sense. Set the floor. Join knowing the start price and the decrement. Expect the timer to extend. Watch the number fall without flinching. And when it crosses your wall, stop. The auction is designed to take your margin. Your only job is to decide, calmly and in advance, exactly how much of it you’re willing to give. The calm version of that decision only exists if you saw the tender early enough to do the maths before auction day. That early sight, with the value and EMD already extracted, is what we built [TrackTender](/subscribe/) to give you — so you reach the auction with your floor already on paper instead of in your head. ## Frequently asked questions What triggers a reverse auction on GeM? The buyer chooses to switch it on, usually for goods and standard services where price decides and the field is large enough for real competition. It never happens first; bids open, technical evaluation runs, and only technically qualified sellers are admitted to the auction. What is the start price in a GeM reverse auction? The start price is the ceiling, and on GeM the auction usually starts from the lowest evaluated price already on the table — the L1 from the sealed financial bids. You can't bid above it. Can you snipe a GeM reverse auction at the last second? No. If a bid lands in the final minutes the clock extends, often by a set few minutes, so every late bid simply resets the timer. The auction ends only when a full extension period passes with nobody bidding. How do you calculate your floor price for a reverse auction? Build it from your all-in delivery cost including freight, taxes you can't pass on and wastage; the EMD and ePBG that lock up capital; the payment-cycle financing gap; and a real margin. Write it down beforehand and treat it as a wall, not a suggestion. What can you see during a GeM reverse auction? You see the current lowest price and your own rank. You don't see who is behind the other bids or how many sellers are still willing to keep going — an asymmetry engineered to pull one more decrement out of you. When should you deliberately lose a reverse auction? When the price has dropped under your floor and shows no sign of stopping. Holding at your floor and letting it pass means you refuse to fund someone else's order at your own expense — which keeps you in business to win the auction that actually makes sense.
