Reverse Auction in Government Tenders: How to Set Your Floor Before It Starts

A reverse auction is designed to find out how low you will go. The only reliable defence is to have decided that in advance, written it down, and to stop there.

How it works

After financial bids are opened, qualified bidders enter a live auction. The current lowest price is visible, and bidders may reduce their offers within the auction window. Prices only go down.

The notice sets the rules: the duration, the minimum decrement between bids, whether the window extends when a bid lands near the close, and whether the starting point is the lowest sealed bid or something else.

Read those rules before the auction, not during it.

Why bidders lose money in auctions

Because the auction supplies pressure and removes time. In a live window, with a visible competitor price and minutes on a clock, the marginal decrement always feels small. Several small decrements later, the price is below cost.

The bidder is not being irrational in the moment. They are making a decision that requires cost analysis in an environment that does not permit it.

Computing the floor

The floor is not your cost. It is the price below which losing is better than winning, which means it is cost plus the minimum contribution that justifies what the contract consumes:

• Direct cost, site overhead and head office overhead
• EMD held, and guarantee commission and margin money for the guarantee's full life
• Retention held through the defect liability period
• The payment cycle, financed by you
• Risk you are carrying, particularly where there is no price variation clause
• The opportunity cost of the capacity this contract occupies

How to price a government tender works through the build-up.

The last item is the one people skip. A contract won at break-even occupies people and plant that could have executed a profitable one. Break-even is not neutral; it is a loss of capacity.

Practical preparation

Know the rules. Decrement size, duration, extension behaviour.

Have your floor visible. On paper, next to the screen.

Decide who is authorised to bid, and give them the floor and no discretion to go below it. A junior person under pressure with no written limit is how floors get breached.

Check your connection and login well before. An auction is not the moment to discover a portal problem. See submitting an e-tender.

Do not plan to "see how it goes." That is a decision to decide under pressure.

Losing well

If the price goes below your floor, stop. Someone else will execute the contract at a price you believe loses money, and one of two things is true: their cost base is genuinely better than yours, or they have made a mistake.

If it is the first, that is real information about your competitiveness in that category and worth acting on. If it is the second, you have avoided their mistake.

Neither is a reason to follow them down.

After the auction

Where you win, the auction price is the contract price. Everything in the build-up now has to hold in execution, which makes a tight auction win a contract that needs disciplined management from day one.

Where you lose, record the winning price against the buyer and category. Over time that record tells you where you are structurally competitive and where you are not, which is worth more than any single tender. See reading award data before you bid and past awards.

Avsar keeps the award history alongside each tender so the floor you compute is informed by what this buyer has actually accepted. See the intelligence module.
