Five tender errors that cost marks before you submit

Most tender teams have a final review.

The problem is that a final review often asks the wrong question.

Instead of asking, "Will this score well?", the team asks whether the document looks finished.

That distinction matters.

A bid can be polished, professional and completely free of spelling mistakes while still leaving substantial marks on the table.

Here are five of the most common problems.

1. Missing part of the criterion

Tender questions often contain several requirements.

A question might ask you to explain your approach to delivery, risk management, reporting and continuous improvement.

A response that explains delivery beautifully but barely addresses reporting has not fully answered the question.

The prose may be excellent. The coverage is not.

The check

Break every question into its individual requirements before reviewing the answer.

Then ask:

Can I point to the exact section that answers each one?

If you cannot, you have found a potential scoring gap.

BidReview's tender review checklist recommends checking every award criterion and sub-criterion individually.

2. Making claims without evidence

"We have extensive experience."

"We have a proven methodology."

"We consistently deliver excellent results."

All three statements sound positive.

None gives an evaluator much to score.

The problem is not that the claims are necessarily false. The problem is that the evaluator cannot award additional marks simply because you say something is true.

Replace claims with evidence.

Instead of:

We have extensive experience delivering complex transformation projects.

Give the evaluator something concrete:

We delivered a three-year transformation programme for a 4,000-user organisation, reducing average processing time by 31% within the first 12 months.

The second statement gives the evaluator something they can point to when justifying a mark.

3. Burying the answer

Evaluators are not reading your tender for pleasure.

They are working through multiple submissions against a scoring framework.

That means your answer should not make them search for the point.

Lead with it.

If the question asks how you will manage mobilisation, begin with your mobilisation approach.

Then explain it.

Then provide the evidence.

Do not spend the first 300 words explaining why mobilisation matters.

The buyer already knows.

4. Ignoring the scoring bands

A surprisingly common review asks:

"Is this a good answer?"

The better question is:

"What mark would this answer receive, and why?"

Scoring forces the team to confront the gaps.

A response might be good enough for a 3/5 while the team assumes it is a 5/5.

That difference matters enormously when the criterion carries significant weighting.

Look at the evaluator's descriptors and ask what specifically separates your answer from the next band.

If the higher band requires "strong evidence", where is that evidence?

If it requires "detailed understanding", what demonstrates that understanding?

5. Leaving compliance until the end

Compliance checks should come first, not last.

A missing mandatory document, incorrect format, incomplete form or missed deadline can undermine an otherwise excellent submission.

The final review should therefore begin with the things that can end the bid outright.

Then check criteria coverage.

Then evidence.

Then scoring.

Then readability and presentation.

That order is deliberate.

BidReview's existing pre-submission tender checklist follows the same principle: check disqualifiers before leaked marks, and leaked marks before presentation.

The five-minute test

Before submitting, pick each quality question and ask five things:

  1. Have we answered every part?
  2. Is every important claim evidenced?
  3. Can the evaluator find the answer quickly?
  4. What band would this receive?
  5. Is there anything that could make the answer fail a threshold?

If the team cannot answer those questions confidently, the bid is not finished.

It has simply been written.

And those are not the same thing.
