FOR PLUMBING, HVAC + HOME SERVICE OWNERS
What a better close rate is worth to your shop.
No new ads. No new trucks. No new hires. Your techs already carry the job to the 10-yard line every day: lead, booked, truck rolls, diagnosis, options. This is what it’s worth to finish more of those drives.
01 / THE LEAK
Every 10 sales calls at a 40% close rate: 4 say yes, 6 say no.
EACH “NO” ALREADY COST YOU
Bought before anyone picked up the phone.
Someone answered, qualified and scheduled it.
A van and a tank of gas to get there.
Your best people’s time, spent on the diagnosis and the options.
FROM MY SHOP’S REAL JOBS




The cheapest growth in your business is the estimates you already wrote.
02 / THE MATH
One point of close rate is one more yes out of every 100 sales calls. Here is what it is worth in a year.
Examples, not benchmarks. Plug in your own numbers below.
03 / FIND YOUR ROW
Say 40% → 50%. Sales calls a month down the side, average sale across the top. Per year.
| CALLS / MO | $1K SALE | $2K SALE | $3K SALE | $5K SALE |
|---|---|---|---|---|
| 50 | $60K | $120K | $180K | $300K |
| 100 | $120K | $240K | $360K | $600K |
| 150 | $180K | $360K | $540K | $900K |
| 200 | $240K | $480K | $720K | $1.2M |
| 300 | $360K | $720K | $1.08M | $1.8M |

Calls × average sale × 12 ÷ 100 per point. An estimate for your shop, not a promise.
04 / EVEN THE SMALL READ
A shop with 120 sales calls a month, a $2,500 average sale and a 40% close rate sells about $1.44M a year. Move from 40% to 44% and that’s +$144K, or 10% more sales. Move to 50% and it’s +$360K, or 25% more.
05 / THE CHEAPEST GROWTH YOU’LL EVER BUY
Ten more points at a 40% close rate is 25% more sold jobs. That’s the same as 25% more leads, without paying for them.
More ad spend. More office time. Lead quality drops as you scale.
Hire and train. Another van lease. Months to ramp.
Same calls. Same trucks. Same team. Same costs.
06 / MY SHOP
I own a plumbing and HVAC company in Central Ohio. Here is the same math on my last 90 days.
Goal: 46% → 56% = $517K a year.
About 17 more sold jobs a month. Just 10 more yeses out of every 100 sales calls.
From my shop’s ServiceTitan tech scorecard, 90 days to Sept 27, 2026. The $517K is a projection, not a result or a promise. Your numbers will differ.
