Bid or No-Bid: A Framework for Choosing the Right Tenders

July 18, 2026 · 6 min read

A mid-sized engineering firm I spoke with last year submitted 31 bids across TED (Tenders Electronic Daily), Portugal's BASE/portal Acingov, and a handful of World Bank notices on UNDB. They won two. The proposals were solid. The problem was upstream: they were bidding on almost everything that matched a keyword, and most of it was never theirs to win. The fix was not better writing. It was a disciplined bid or no-bid decision made before a single page of the proposal got drafted.

Bidding is expensive. A serious response to a public tender can absorb anywhere from a few days to several person-weeks, plus translation, certifications, bid bonds, and the opportunity cost of the senior people who should be delivering paid work. Every "yes" to a low-probability tender is a quiet "no" to a better one. The goal of a bid or no-bid framework is simple: spend your proposal budget where it actually converts.

Start With Hard Gates, Not Gut Feel

Before you score anything, run the tender through a small set of pass or fail filters. If it fails any one of these, it is a no-bid, regardless of how attractive the contract looks.

Eligibility and exclusion grounds. Do you meet the legal and financial criteria? Many EU notices set minimum turnover (often capped at twice the contract value under the 2014 Procurement Directives), insurance levels, and require an ESPD (European Single Procurement Document). Missing one mandatory certificate, an expired ISO 9001, a CE marking you do not hold, disqualifies you on page one.

Deadline reality. Open procedures under the EU directives run a minimum of around 35 days, but complex bids need every one of them. If you find the notice with eight days left and it requires a notarised consortium agreement, be honest.

Mandatory references. If the tender demands three comparable projects above a value you have never delivered, no narrative will paper over it.

Show-stopper terms. Unlimited liability, a bid bond you cannot fund, payment terms of 90-plus days you cannot carry, or a jurisdiction clause you will not accept.

Hard gates protect you from the most common waste: pouring effort into a tender you were never legally or operationally able to win.

Score the Four Dimensions That Matter

Tenders that clear the gates move to scoring. Rate each on a simple 1 to 5 scale across four dimensions, then weight them.

1. Strategic fit (weight 25%). Does this contract move you somewhere you want to go? A reference with a national health service, an entry into a new country, or a framework agreement that unlocks repeat call-offs is worth more than a one-off of the same size. A tender can be winnable and still be a no-bid if it pulls you off strategy.

2. Capability fit (weight 30%). How closely does the scope match what you genuinely do? Score a 5 when it is squarely your core offer and a 2 when you would be subcontracting half of it or learning on the client's budget. Be ruthless. Buyers in regulated sectors (medical, defence, rail) read straight through stretch.

3. Win probability (weight 30%). This is where most firms lie to themselves. Look for the tells:

Is there an incumbent? Defending suppliers win a large share of recompetes, so an unknown buyer with a happy incumbent is a steep hill.

Did you shape the requirement? If the first time you heard of this need was the published notice, your odds drop sharply versus a buyer you have been talking to for months.

How price-driven is the award? Check the award criteria split. A 70% price, 30% quality weighting rewards the lowest cost base, not the best solution.

How many bidders do you expect? A niche, complex scope with three plausible bidders is very different from a generic supply tender with twenty.

4. Profitability and risk (weight 15%). Estimate the realistic margin after the true cost of delivery, then discount it for risk: penalties, scope ambiguity, currency exposure in cross-border work, and payment reliability of the contracting authority.

Multiply each score by its weight and total it. Set a threshold (say 3.2 out of 5) below which you do not bid without a senior override. The discipline is in honouring the threshold.

Weigh It Against the Cost of Bidding

Score tells you how good the opportunity is. It does not tell you whether it is worth the spend. Put a real number on the cost of bidding: estimated person-days at loaded cost, plus translation, legal review, bid bond fees, and any travel or sampling. Then compare it to expected value.

A rough but honest calculation: expected value = contract margin x win probability. If a tender carries 40,000 in realistic margin and you put your win probability at 20%, the expected value is 8,000. If your bid will cost 10,000 to prepare, the math says walk away, even though the contract looks big. Run this for every shortlisted tender and a portfolio view appears: you stop chasing large, crowded, price-led contracts and start winning the smaller, specialised ones where your odds are real.

A Simple Matrix You Can Use Today

Plot every qualified tender on two axes: fit and win probability (your combined score) against cost and effort to bid.

High fit, low effort: bid, and bid well. These are your bread and butter.

High fit, high effort: bid selectively. Commit only what you can resource without starving the easy wins.

Low fit, low effort: bid only to keep a buyer relationship warm or to build a reference, never as a habit.

Low fit, high effort: no-bid, every time. This quadrant is where good firms quietly bleed.

Keep a one-page bid or no-bid log: the decision, the scores, and the reasons. Six months later you can see whether your win-probability estimates were honest, and recalibrate.

The Monitoring Problem Underneath All of This

None of this works if you only see half the tenders, or see them too late to qualify them properly. The firms that bid badly are often the ones drowning: refreshing TED, BASE, SAM.gov, UNGM, and a dozen national portals by hand, then scrambling when something surfaces with a week to spare. Good qualification needs early sight and breathing room.

That is the quiet case for a daily, scored feed of matched tenders. When relevant opportunities arrive filtered to your sectors and countries, ranked by fit, with the deadline and award criteria visible upfront, the bid or no-bid decision becomes calm and routine rather than a last-minute gamble. You spend your judgement on which tenders to win, not on finding them.
