Win/loss analysis for bid teams
A win rate tells you how often you win, not why. This guide covers what to record after every tender, how to get and read a debrief, the handful of numbers worth tracking, and a quarterly review that turns results into better bids. It comes with a free outcome-log template.
Why most bid teams don’t learn from their results
Most firms know their win rate. Far fewer know why they win or lose, because the reasons live in people’s heads and fade within weeks. When the next similar tender arrives, the team repeats the same pricing, proposes the same weak expert, or makes the same compliance slip.
Win/loss analysis is simply a habit: record a few facts about every tender you decide on, ask for feedback every time you lose, and review the record on a fixed schedule. It costs a few minutes per bid, and it is the only reliable way to improve both your proposals and your bid/no-bid decisions.
What to record after every tender
Record the result as soon as it is known, while the details are fresh. These fields cover almost every question you will want to answer later:
| Field | Why it matters |
|---|---|
| Result | Won, lost, cancelled or withdrawn. Cancelled tenders are not losses and should not drag down your win rate. |
| Published budget or estimate | The reference point for every price comparison. |
| Our price and the winning price | Shows whether you are pricing above the market, and by how much. |
| Our technical score and the winner’s | Where the evaluation discloses them, the clearest signal of how far your proposal is from winning. |
| Winner | Over time, tells you who you keep losing to, and where. |
| Main loss reason | One primary reason per loss, so results can be compared (see below). |
| Debrief notes | What the contracting authority told you, in its words. |
| Lessons learned | One or two sentences on what you would do differently next time. |
Record the tenders you decided not to bid, too, with the reason and the stage you decided at. Without them you can only see whether you win the bids you chase, not whether you are chasing the right ones.

Pick one main loss reason
Most losses have several causes, but if every loss lists five reasons you can never count anything. Choose the one that decided the outcome from a short, fixed list: Price, Technical score, Disqualified, Late submission, Cancelled, Other. Put the nuance in the lessons learned.
- Price: you passed the technical evaluation and lost on the financial score.
- Technical score: another tender scored higher on quality, or yours fell below the technical threshold.
- Disqualified: the tender was rejected for non-compliance, such as a missing document, an eligibility problem or a format error.
- Late submission: the tender arrived after the deadline.
- Cancelled: the contracting authority cancelled the procedure. Track these separately from losses.
Disqualification and late submission are worth singling out: they are entirely within your control, and every one of them wasted the full cost of the proposal. The target for both is zero, and a single case deserves a fix to your submission process, not just a note.
Always ask for a debrief
The contracting authority’s view of your tender is the most valuable feedback you will get, and donor rules give you a way to ask for it.
Under PRAG, the European Commission’s rules for EU external-action contracts, the contracting authority must inform unsuccessful tenderers in writing when it notifies the award. For service contracts of €300,000 or more, the contract can only be signed after a standstill period of 10 calendar days when the notification is sent electronically, or 15 days otherwise. Unsuccessful tenderers can request further information, and the contracting authority may disclose anything that is not confidential, for example comments on the strengths and weaknesses of their tender, so they can do better in future tenders. World Bank-financed procurement likewise lets unsuccessful bidders request a debriefing from the borrower once the intended award has been notified. Check the deadlines in each tender’s documents, because they are short.
What to ask
Ask in writing, promptly, and keep the questions specific:
- Our technical score for each evaluation criterion, and where we lost the most points.
- How our key experts were assessed against the requirements.
- The winning technical score and price, where these can be shared.
- Any compliance issues, however minor, that the committee noted.
Then read the answers against the evaluation grid published with the tender. Points lost on one criterion in several debriefs point to a repeatable weakness, such as the methodology section or a particular kind of expert.
The numbers worth tracking
Win rate, by segment
Your overall win rate hides more than it shows. Break it down by sector, funder and country, and count only decided bids: wins divided by wins plus losses, leaving cancelled tenders out. Treat small samples with care. With ten decided bids in a segment, a single result moves the win rate by ten percentage points.
Winning discount
The winning discount shows how far below the published budget or estimate the winning price landed:
winning discount = (budget − winning price) / budget
If the budget was €1,200,000 and the contract went for €996,000, the winning discount was 17%. Take the median across tenders in the same sector or funder, rather than the average, so that one unusual award does not skew the picture. Comparing your own price on the same basis shows how far off the market you are: in that example, a €1,080,000 offer sat about 8% above the winning price.
Technical gap
Where scores are disclosed, record the gap between your technical score and the winner’s. A consistent gap of several points is a proposal-quality problem, and as the price check in our bid/no-bid guide shows, a lower price rarely closes it in quality-weighted evaluations.
Who beats you
Count how often each competitor wins against you, in which sectors, and at what typical winning discount. A handful of names usually accounts for most of your losses, and knowing their pricing habits tells you which tenders are worth contesting.
Process failures
Disqualifications plus late submissions, as a share of submitted bids. This should be zero.
Run a quarterly review
Recording results only pays off if someone looks at them. Once a quarter, put an hour in the diary with the bid managers and whoever signs off on bid/no-bid decisions, and work through the same agenda:
- Process failures. Any disqualification or late submission, its cause, and the fix.
- Price. Your offers against the winning discount in your main sectors and funders.
- Technical gaps. Criteria where debriefs keep showing lost points.
- Competitors. Who beat you most often, and whether that changes which tenders you pursue or who you team with.
- Bid/no-bid calibration. Compare the decision scores of the bids you won and lost. If low-scoring bids win as often as high-scoring ones, your scoring criteria need adjusting.
- Track record. References and CVs that evaluators rated weak, to update before the next tender. The key expert CV guide shows how evaluators score CVs.
End each review with no more than three changes, each with an owner. A short list that gets done beats a long one that doesn’t.

Track outcomes in BidderOps
Each opportunity has an Outcome tab for the result, award value, winner, loss reason and lessons learned, and tenders you decide not to bid stay in an archive with their rationale. From those records, BidderOps calculates winning-discount benchmarks by sector and funding source, builds profiles of the competitors who beat you, and uses your results to sharpen the win probability on every new bid.
