Improving Your Proposal Win Rate: Measure and Steer
The win rate of proposals (or quotes: the words are used interchangeably) is the share of sent proposals that get accepted, by count or by value, over a fixed period. An agency that sends 40 proposals in a quarter and wins 14 of them is at 35% by count. It is the number that determines how much you need to quote to hit your revenue target, and therefore how many non-billable hours go into business development. This article covers how to calculate the win rate, what a normal percentage is, where proposals fail in practice, and six changes that raise the percentage without you having to get cheaper.
Calculating the win rate: count or value, and over which period
Two choices determine whether the number means anything.
Count or value. By count every proposal weighs the same; by value large proposals weigh more. An agency that wins many small jobs and loses the large ones sees 45% by count and 20% by value. Track both; the gap between them is a signal in itself.
The period of the proposal, not of the decision. Count a proposal in the quarter in which it was sent, and judge that quarter only once the decision window has passed. Otherwise every current quarter looks worse than it is, because the open proposals have no outcome yet.
win rate = won proposals ÷ (won + lost + expired) × 100%
Expired proposals (no answer, validity date passed) count as lost. Leaving them out flatters the number: at most agencies, "no answer" is the largest category.
What is a normal win rate for an agency?
There is no industry benchmark that applies everywhere, because the percentage mainly depends on when you quote. As a guideline for agencies and consultancies:
| Situation | Win rate by count |
|---|---|
| Follow-up engagement with an existing client | 60 to 80% |
| Warm request after a conversation, single bidder | 40 to 60% |
| Request with two or three competitors | 25 to 40% |
| Cold request, tender or public procurement | 10 to 25% |
An agency average of 30 to 45% is healthy by that measure. If it sits structurally above 60%, you are probably quoting too late in the conversation or too cheaply; below 20% you are quoting too early, to too many parties, or to the wrong ones.
Where proposals fail in practice
Agencies that call back on their lost proposals rarely hear "too expensive" as the first reason. The real causes, roughly in order of how often they occur:
1. No decision. The client chose nobody. The project was postponed, the budget holder changed, or the question was never urgent enough. This is the largest category and the only one you can prevent before you write the proposal.
2. No follow-up. The proposal was sent, the client opened it, and then it went quiet, on both sides. After three weeks the attention is gone.
3. Wrong scope. The proposal answers the request, not the problem. The client asked for a website and had a lead problem.
4. Too much choice or too little. One option without an alternative feels like take it or leave it; five options with six lines each nobody reads to the end.
5. Price. It does come up as a reason, but usually only when one of the four above was also in play.
Six changes that raise the win rate
1. Qualify before you quote. Three questions in the first conversation: is there a budget, who decides, and when does it need to be done? If you get no answer to one of them, write a one-page exploratory proposal instead of a full quote. Fewer proposals, higher percentage, and the hours you save are billable elsewhere.
2. Record a probability per opportunity, and check whether it was right. Put a percentage on every opportunity in the pipeline and compare the estimate with the outcome after a quarter. Agencies that do this discover they underestimate warm requests and overestimate tenders, and start dividing their time differently. In Horixa the probability is a field on the opportunity, and Insights uses it to calculate the weighted pipeline value.
3. Make accepting the easiest action. A PDF that has to be printed, signed, scanned and emailed back loses to a link with one button. Let the client open and accept the proposal online, and make sure the acceptance is recorded with a timestamp. See what an interactive proposal is and what it does and does not include.
4. Give the proposal a validity date and use it. Not as a pressure tactic, but as an occasion: a week before the date you call, not to ask "whether there is any news", but to ask what is still missing to decide. A proposal that expires without a touchpoint was never a real opportunity.
5. Offer two options, not one and not five. A basic version and a fuller one, with the difference explained in one sentence. The client then chooses between two yeses instead of between yes and no.
6. Let the proposal be the project. If the budget from the proposal also becomes the budget of the project, and work outside that budget is visible, you do not have to pad the proposal to be "safe". You can quote sharply, because you know that whatever falls outside it is treated as out-of-scope work rather than as a loss. In practice that is the biggest lever on price without touching the margin.
Worked example: what five percentage points are worth
A consultancy sends 120 proposals per year with an average value of €15,000 and wins 35%: 42 engagements, €630,000. Each proposal costs an average of eight hours in conversation, writing and follow-up: 960 non-billable hours per year.
| 35% | 40% | 35%, but 20% fewer proposals | |
|---|---|---|---|
| Proposals sent | 120 | 120 | 96 |
| Won | 42 | 48 | 34 |
| Revenue | €630,000 | €720,000 | €504,000 |
| Hours in business development | 960 | 960 | 768 |
Five percentage points higher is €90,000 in revenue here for the same business development effort. And the third column shows why qualifying (change 1) only pays off if the percentage rises with it: quoting less without choosing more sharply just costs revenue.
Frequently asked questions
How do you calculate the win rate of proposals? Won proposals divided by all sent proposals with an outcome (won, lost and expired), times 100%. Calculate by count and by value, and assign proposals to the period in which they were sent.
What is a good win rate for proposals? For an agency or consultancy, 30 to 45% by count is healthy, with large differences per situation: follow-up engagements with existing clients win 60 to 80%, tenders and cold requests 10 to 25%.
What is the difference between win rate and probability? Win rate is the realised percentage after the fact. Probability is the estimate beforehand per opportunity, which you use to calculate the weighted pipeline value. By putting the two side by side after every quarter, you learn to estimate better.
Why are proposals not accepted? Usually not because of the price, but because the client chose nobody (no budget, no urgency, change of decision-maker), because follow-up stalled, or because the proposal answered the request and not the problem.
Does an online proposal help the win rate? Yes, for two reasons: accepting is one click instead of printing, signing and scanning, and the acceptance is recorded immediately, so there is no dispute about what was agreed. In Horixa the client opens the proposal via a link without an account and accepts with one click; the acceptance is recorded with a timestamp.
How do I track the win rate of proposals in software? With a sales pipeline in which every opportunity has a stage, a value and a probability, and in which won and lost opportunities keep their status. In Horixa that pipeline is in every plan, and Insights (from the Growth plan) calculates the weighted pipeline value.
