What it means
The word carries two closely related meanings, and which one applies depends on who is offering what. In markets, a bid is a buyer's price, sitting opposite the seller's ask.
In procurement and construction, a bid is a supplier's proposal to carry out work at a price the supplier sets. In the procurement sense a bid is a substantial document rather than a number.
It sets out the price, what is included and excluded, how long the price holds, the delivery schedule, and commercial terms such as payment timing and liability caps. Buyers score all of these together, which is why the cheapest bid does not automatically win.
Pricing a bid means building it from the bottom up. You cost the direct labour and materials, add a share of overheads such as insurance, premises and supervision, then add a margin for profit and risk.
Get the overhead allocation wrong and you can win plenty of work while quietly losing money on every job. Bids are normally binding for a stated validity period, often 30 to 90 days, which protects the buyer from a supplier withdrawing part way through evaluation.
Large public contracts sometimes require a bid bond, a guarantee that the winner will actually sign the contract, forfeited if they walk away. Bid discipline is a genuine management skill.
Chasing every opportunity spreads the bidding team thin and pushes down the average win rate, while a deliberate decision not to bid frees resource for the opportunities you can realistically win. Tracking win rate and the cost of bidding turns that judgement into numbers the business can manage.
In practice
Real-world examples.
Example
A civil engineering firm bids $8,400,000 for a bridge repair contract, including a $250,000 risk allowance for ground conditions. The allowance is itemised separately so the client can see exactly what is being priced for.
Example
A day trader watching a share quoted at 41.20 bid and 41.35 ask places a limit order to buy at 41.22, improving on the existing bid to move to the front of the queue rather than paying the full ask.
Example
A catering company decides not to bid for a hospital contract after scoring it against its own criteria. The scope requires a night shift capability it does not have, and the $30,000 cost of preparing the submission is redirected towards two smaller opportunities it is well placed to win.
Formula
Calculation
For a procurement bid built up from cost:
Total Cost = Direct Costs + Allocated Overhead
Bid Price = Total Cost + Margin
Worked example. A commercial fit-out contractor is bidding for an office refurbishment. Direct labour and materials come to $340,000. The company recovers overhead at 18% of direct costs and targets a margin of 12% on total cost.
Allocated Overhead = $340,000 x 0.18 = $61,200
Total Cost = $340,000 + $61,200 = $401,200
Margin = $401,200 x 0.12 = $48,144
Bid Price = $401,200 + $48,144 = $449,344
The contractor submits $449,344 and knows that any price below $401,200 loses money once overheads are properly counted. If competitive pressure forces the price down to $420,000, the margin falls to $420,000 - $401,200 = $18,800, which is only 4.7% of total cost and probably too thin to absorb any site problems.Case study
Seen in the real world.
Tremont Mechanical is a fictional heating and ventilation contractor used here as an illustrative example. It had been winning around 45% of the contracts it bid for, which the sales director considered excellent until the finance director looked at margins across the completed jobs.
The problem was in the overhead recovery rate. Tremont had been applying 9% to direct costs, a figure set six years earlier, while actual overheads had grown to nearer 17% of direct costs after two office moves and a larger estimating team. Bids were therefore priced roughly 8% below where they should have been, and the high win rate was a symptom rather than a success.
Tremont recalculated the recovery rate, repriced its live bids, and introduced a formal decision on whether to bid at all, scoring each opportunity for fit, competition and margin potential. The win rate fell to 28% over the following year, but gross margin on completed work rose from 6% to 14%, and the bid team spent its time on fewer, better opportunities. This is an illustrative story, but the pattern behind it is common.
Watch out
Common mistakes.
- Confusing margin with markup, so a bid priced at cost plus 12% markup delivers less than a 12% margin on the final price.
- Using an out of date overhead recovery rate, which makes bids look competitive while eroding profit on every job won.
- Bidding for everything that arrives, which dilutes quality across submissions and lowers the overall win rate.
Questions
People also ask.
What is the difference between a bid and a quote?
A quote is usually a simple price for defined goods or services, while a bid is a fuller competitive submission covering price, scope, timing and terms.
Can you withdraw a bid after submitting it?
Not usually within the stated validity period, and on public contracts a withdrawal can mean forfeiting a bid bond.
How do you know whether to bid?
Score each opportunity for how well it fits your capability, how strong the competition is, and what margin is realistically achievable, then decline the ones that fail.
