A contractor growth score measures the three places home-service revenue leaks the most (calls you don't answer, leads you respond to slowly, and leads you never book) and turns them into one number that shows where your money is going. Most shops are quietly losing a fifth to nearly half of the work they already paid to generate, and they have no idea, because the lost jobs never show up on an invoice.
You can't fix a leak you can't see. This is how to find yours.
The revenue you're losing doesn't show up anywhere
Here's why this problem hides so well. When you win a job, you see it: the deposit, the truck rolling out, the invoice. When you lose one to a missed call or a slow callback, you see nothing. There's no line item for "homeowner who called at 7:12 and booked your competitor at 7:15." The money never arrives, so it never gets counted. That's the most dangerous kind of revenue leak, the kind that feels like business as usual.
So owners look at a full schedule and assume things are working. Meanwhile the leads they paid for keep slipping out the back: a roofer misses six calls during a tear-off, a plumber's voicemail eats a Saturday emergency, an HVAC office takes four hours to call a lead back who'd already booked someone else. Each one is small. Added up across a year, they're often the difference between plateauing and growing.
The three numbers that decide your growth
Growth in a service business isn't mysterious. It comes down to three measurable points, and a growth score puts a number on each.
Answer rate. What percent of inbound calls do you actually pick up, live, the first time? Most owners guess high and measure low. Every unanswered call is a homeowner with money out who is now dialing the next name on the list.
Response speed. When a lead comes in (a missed call, a form, a text) how long before someone responds? This is the response gap, the window between a lead raising their hand and you reaching back. In home services it's measured in minutes, and minutes decide who wins.
Booking conversion. Of the leads you do reach, how many turn into a scheduled job? A great answer rate means nothing if the call ends in "we'll call you back" instead of a time on the calendar.
Why fixing leaks beats buying more leads
When growth stalls, the reflex is to spend more: more ads, more lead services, a bigger marketing budget. But pouring leads into a leaky business is the most expensive way to grow. If you're booking half the leads you could, every new lead you buy gets the same broken handling and the same loss rate. You're paying full price to lose jobs faster.
Plugging the leak does the opposite. The leads are already there and already paid for. Lifting your answer rate, tightening response speed, and closing more of what you reach raises revenue without raising spend. That's the cheapest growth in your business, and it's sitting in the gaps you can't currently see.
How to score your own business today
You can get a rough read this week with no tools. Pull your call log and count, over the last month, how many inbound calls went unanswered. Then take your last twenty leads and write down how long each waited for a response and whether it ended in a booked job. Three honest numbers (answer rate, average response time, booking rate) and you'll already see which gap is costing you most.
For the precise version, the Contractor Growth Score measures all three, scores them against what high-performing shops in the trades actually hit, and shows you the dollar value of each leak in about three minutes. It turns "I think we're doing fine" into a number you can act on.
What you do with the number
The score isn't the point. The fix is. Once you know which gap is widest, the move is obvious: if you're missing calls, you build coverage so calls get answered whether or not you're free. If response is slow, you put a system on it instead of relying on memory. If booking is weak, you tighten what happens on the call. The shops that break through their plateau don't work harder on all three at once. They find the biggest leak and close it first.

Frequently Asked Questions
A contractor growth score is a quick diagnostic that measures the three points where home-service revenue leaks most: how many calls you answer, how fast you respond to leads, and how many of those leads you book. It turns those into one number that shows where you're losing money.
Start with the leaks you can't see: missed calls, slow lead response, and leads that never get booked. Measure your answer rate, your response time, and your booking conversion. Most owners find the biggest losses sit in the calls and leads they never knew they dropped.
It varies by shop, but missed calls, slow response, and weak follow-up commonly cost a home-service business a fifth to nearly half of the jobs it already paid to generate. The leads exist; they just slip through gaps in how calls and follow-up are handled.
