Most bids don’t lose because they’re weak. They lose because they leak marks — a point here, two points there — across answers that everyone on the team thought were fine. The losses are quiet, predictable, and almost always fixable before submission, if you know what to look for.
If you understand how procurement panels actually score quality, the leaks make sense: every one is a place where you’ve made it hard for a time-pressured evaluator to award you the mark you deserve. Here are the ones that do the most damage.
1. Claims with no evidence
The single biggest cause of lost marks. “We have a proven track record.” “Our methodology ensures success.” “We are committed to quality.” These are claims, and a claim is unscoreable — the evaluator has nothing to point to, so they default to the middle band.
The fix: behind every claim, put a named, specific, verifiable proof point. A client, a number, a date, an outcome. At least one for any heavily weighted answer.
2. Answering the topic instead of the criterion
Teams write what they want to say about a subject rather than what the criterion is actually asking to be marked. The response reads well and scores poorly, because half of it is being marked against a requirement it never addressed — or not marked at all.
The fix: map every criterion and sub-criterion before writing, and make it obvious which requirement each paragraph answers. Mirror the language of the criterion.
3. Burying the answer
Evaluators scan. If your direct answer is three paragraphs down, after the context and the preamble, there’s a real chance it’s skimmed past — and an answer that isn’t seen can’t be scored.
The fix: lead with the answer. State your approach in the first line or two, then support it. Write so the mark is earnable in the first ten seconds of reading.
4. Ambiguity and hedging
“We would aim to,” “where possible,” “subject to,” “we hope to.” To you, these feel honest and careful. To an evaluator scanning for risk, they read as exactly that — risk — and risk is the easiest thing to mark down.
The fix: commit. Replace conditional language with definite statements of what you will do, how, and by when.
5. The generic ceiling
A response can be complete, compliant, well structured and well written — and still land at a 6 or a 65. A structurally complete answer with no specific proof is, by definition, a mid-band answer. Generic competence has a ceiling, and it sits close to the pass line.
The fix: don’t try to break the ceiling by writing more. Break it with evidence the evaluator can point to. (See procurement scoring matrix examples for what separates a mid-band answer from a top-band one.)
6. Unread, uncaptioned graphics
A diagram with no benefit-led caption is decoration. Evaluators under time pressure read captions; if the caption doesn’t tell them what the graphic proves, the graphic earns nothing — and the space could have carried evidence.
The fix: every visual gets an active, benefit-led caption that states what it demonstrates and why it matters to this requirement.
7. Ignoring the weightings
Most teams spread effort evenly across the document. But a five-point gain on a 30%-weighted answer is worth six times a five-point gain on a 5% one. Polishing low-weight answers while high-weight ones sit under-evidenced is one of the most expensive habits in bidding.
The fix: weight your effort by the marks. Put your best evidence, your best people, and your final review hours where the score actually lives.
8. Failing the qualifying thresholds
Many tenders set minimum scores on individual criteria — fall below and you’re out, regardless of your total. A single under-evidenced mandatory answer can disqualify an otherwise winning bid.
The fix: identify every threshold and pass/fail gate first, and make certain each of those answers clears it before you worry about maximising elsewhere.
The pattern behind all eight
Every one of these is the same mistake wearing a different hat: making the evaluator work to find your marks, instead of handing them the justification. Fix that, and the leaks close.
The reliable way to catch them is to stop reading your bid as the author and start scoring it as the evaluator will — in their band language, hunting for the deduction. There’s a repeatable method for that in Bid review methodology.
