Here's a number most contractors don't track: their proposal close rate.
Not a rough guess. Not "I close most of them." The actual number — proposals sent versus contracts signed — over the last 90 days.
If you don't know that number, you're probably leaving more money on the table than you realize. And the fix is often simpler than it looks.
How to Calculate Your Proposal Close Rate
Take the last three months of proposals you sent. Count them. Then count how many turned into signed contracts or paid deposits.
Divide signed by sent. Multiply by 100. That's your close rate.
If you sent 12 proposals and closed 5, your close rate is 41.7%.
Industry benchmarks vary by trade and market, but most experienced contractors are somewhere between 30–60%. Anything below 30% on qualified leads — people who actually reached out wanting a quote — is usually a proposal problem, not a pricing problem.
What a 10% Improvement Is Actually Worth
This is the number that tends to surprise people.
Let's say you send 15 proposals per quarter at an average job value of $8,000. At a 35% close rate, you're closing 5.25 jobs — call it 5 — worth $40,000.
Lift that close rate to 45% and you're closing 6.75 jobs — call it 7 — worth $56,000. That's $16,000 in additional revenue from the same number of leads, the same amount of marketing spend, and the same amount of time bidding.
The close rate is one of the highest-leverage numbers in the business because everything upstream — lead generation, advertising, referrals — is already spent by the time the proposal goes out. Improving how often the proposal converts turns sunk cost into recovered revenue.
Where Close Rate Breaks Down
Most close rate problems aren't random. They're concentrated in specific situations.
The jobs you bid but should have pre-qualified: If you're sending proposals on jobs where the client hasn't been through any kind of qualifying conversation, you're converting exploratory shopping into real proposals. That tanks your rate and wastes hours.
The proposals that go cold after 5 days: There's usually a 72-hour window where the client is actively deciding. After that, the deal is effectively in limbo. If you're not following up inside that window, you're handing the decision back to inertia.
The proposals that feel like templates: Clients compare proposals side-by-side. If yours looks identical to the next one — same structure, same boilerplate opener, same line-item list — the differentiator becomes price. Defaulting to price is almost always the wrong place for the decision to land.
The Fastest Lever
The fastest-moving lever in close rate improvement, consistently, is the opener.
Most contractor proposals open with a generic header and "thank you for the opportunity to submit this proposal." The client has already read that sentence six times. It registers as a form.
The proposals that convert open with proof of listening. A sentence or two that reflects the specific concern from the conversation, the specific job context, the specific outcome the client is trying to reach. Not the general category of work — the actual job.
"You mentioned the main concern was the existing drainage running toward the neighbor's property. We've scoped the grading to redirect to the southeast corner with a French drain along the fence line, which resolves that before we touch anything else."
That opener signals: this contractor was listening. This proposal was written for this job. The price that follows feels like it belongs to a real plan, not a generic estimate.
The Second-Fastest Lever
The close happens at the end — or it doesn't happen at all.
Most proposals end with something like "let us know if you have any questions." That's not a call to action. That's a passive handoff that leaves the client with no instruction about what to do next.
A strong close is specific and low-friction: "If this looks right, I'd like to get the start date on the calendar. I'm available Tuesday and Thursday afternoon this week — want to do a quick 15 minutes to confirm the scope and lock in the timeline?"
The ask is clear. The commitment is small. The next step is obvious.
Tracking It Forward
Once you calculate your current close rate, put it somewhere you'll see it. Even a running tally on paper: "proposals sent this month / closed." Measure it the same way every quarter.
Most contractors who start tracking it start seeing it improve — not because tracking magically converts deals, but because knowing the number changes the behavior. You pay attention to proposals differently when you're watching whether they close.
And when the number doesn't improve despite better proposals, that's the signal to look at lead quality, pre-qualification, or pricing — not proposal format.
The Proposal Audit
If you want a read on why your current proposal isn't converting, the Proposal Audit Report is a free diagnostic that identifies specific friction points in your opener, scope definition, and close structure.
Most contractors who run it are surprised by how targeted the output is. It's not a generic "improve your proposals" recommendation — it tells you where the specific breakdown is in the document you're actually sending.
Run it free. If the upside is clear and the deal is still active, the Proposal Teardown Sprint takes the diagnosis to a fix map inside 72 hours.
Close rate math is simple. Improving it — with the right proposals, tracking the right signals — is what separates the contractors who outperform the market from the ones who compete on price by default.
