How to Price a Competitive Tender Without Leaving Money on the Table
July 19, 2026 · 7 min read
Picture a contractor in Lisbon who wins a public cleaning contract by undercutting the field by around 22 percent. Eighteen months later he handed it back. He had priced for the work he could see and forgotten the work he could not: cover for sick leave, the consumables clause buried in annex three, and the payment gap that ran past 60 days on a public buyer. The job looked profitable on his spreadsheet and ran at a loss in his bank account. He did not lose the tender. He won the wrong number.
That is the real risk in competitive pricing. The loud failure is bidding too high and losing. The quiet, more expensive failure is bidding too low and winning. Here is a practical way to land on a number that takes the award and still pays you.
Build Your Cost Base Before You Think About Price
Price is the last decision, not the first. Start with a clean, bottom-up cost build-up so you know your real floor before any competitor or margin enters the conversation.
A defensible build-up usually separates four layers:
That last layer is the one most bidders skip, and it is brutal on public contracts. Under the EU Late Payment Directive, public authorities are meant to pay within 30 days (60 in defined cases), but enforcement varies and real-world delays are common across many markets. If you finance three months of payroll while you wait, that is a financing cost, and it belongs in the price, not in your overdraft.
Set Margin Against Risk, Not Against Hope
Once the floor is solid, margin is a deliberate choice, not a reflex percentage. The right markup depends on how much can go wrong and how badly you want this particular contract.
Push margin up when the scope is vague, the contract is long and fixed-price, the buyer is new to you, or you are exposed to input prices you cannot hedge (steel, fuel, freight). Pull margin down, with eyes open, when the work is repeatable, the client is a strategic foothold, or the contract anchors your utilisation for a year and lets you bid the next three from a position of strength.
What margin should never absorb is a costing mistake. A thin, honest margin on a complete cost base is survivable. A healthy margin on a cost base that forgot mobilisation, demobilisation, or the bond is a trap with a bow on it. Price the risk explicitly so you can see what you are giving away when you discount.
Benchmark Competitors From Evidence, Not Folklore
You are not pricing in a vacuum, so study the field, but study it from records rather than rumour. Public procurement is unusually transparent if you know where to look.
Read these to understand the *spread*, not to copy a figure. The goal is to know roughly where the cluster of serious bids will land so your price is competitive without being reckless. A bid 40 percent below the historical average is not a masterstroke. It is usually a missing cost line.
Respect the Abnormally Low Bid Rule
There is a hard floor below which low pricing stops being clever and starts being disqualifying. Under EU rules (Directive 2014/24/EU, transposed into national law), buyers can, and in some cases must, investigate a tender that appears abnormally low. They write to you, ask you to justify the figure, and reject the bid if the explanation does not hold.
Many national systems apply a rough trigger when a bid falls well below the average of the others or below the estimate, often in the region of 15 to 30 percent depending on the regime and the number of bidders. Treat any such threshold as a warning line, not a target. If you are heading toward it, either you have a genuine, documentable cost advantage (your own factory, idle capacity, a fully amortised fleet) that you can prove on demand, or you have made an error. Have the justification file ready before you submit. Winning the abnormally-low argument is far easier when your cost build-up is already written down.
Compete on Value, Not Only on the Number
Lowest price loses its grip the moment the buyer scores on quality. Most modern public tenders are awarded on MEAT (the most economically advantageous tender), where price is one weighted criterion among several: technical quality, delivery time, lifecycle cost, warranty, environmental and social value, and after-sales support.
That changes the maths. If price carries, say, 40 to 60 percent of the score, a slightly higher number paired with a genuinely stronger technical and service offer can beat a cheaper, thinner bid. So before you sharpen the pencil, read the award criteria and their weightings, then invest where the points are. Quantify total cost of ownership when your kit lasts longer or uses less energy. Show the service level, the spares, the response time. Make the evaluator's spreadsheet reward what you are actually good at, rather than racing to the bottom on the one axis where someone will always go lower.
Bringing It Together
A winning, profitable price is a sequence: cost build-up first, risk-weighted margin second, competitor evidence third, the abnormally-low line as a guardrail, and value framing on top. Skip a step and you either price yourself out or win something that drains you.
The hard part is rarely the arithmetic. It is finding the right tenders early enough to price them properly, with days to model costs rather than hours to copy last year's number. That is the case for a daily, scored feed of matched opportunities: when relevant tenders arrive ranked by fit instead of waiting to be discovered, you spend your time on the build-up that wins the award and keeps the margin, not on the search that runs out the clock.
