Most detailing shop owners think they have a pricing problem. They don't. They have a math problem they've never bothered to do.
A shop owner I know runs a solid operation — two bays, good reviews, a waiting list in peak season. He was proud of it. When I asked him what his close rate was on new inquiries, he gave me the contractor's universal answer: a blank stare followed by a number he made up. "Maybe 40 percent?" We pulled his actual numbers. Instagram DMs, web form submissions, missed calls, texts that sat for a day before getting answered. Real close rate: 11%. He was losing nearly nine out of every ten leads — and had convinced himself he was doing fine because the bays stayed full. He wasn't full. He was surviving on the fraction of customers patient enough to wait him out.
Here is the number you need to tattoo somewhere visible: the industry proxy for home services conversion is about 1 in 5 inquiries becoming a booked job. That's your 20% benchmark. Your real number is almost certainly lower.
The research on this isn't new, but nobody in this industry talks about it. MIT tracked lead response behavior for years — their finding: 78% of customers buy from the first business that responds (MIT Lead Response Management Study, Dr. James Oldroyd, 2007). First. Not the cheapest. Not the most reviewed. The first. That same study found that responding within five minutes makes you 100 times more likely to reach a prospect than if you wait thirty minutes. One hundred times. Not 10. Not double. A hundred.
The average business in this country takes 47 hours to respond to an inbound inquiry (Drift/InsideSales, 2017). More than half of all contractors — across every trade — take five days or longer. And the brutal end of the funnel: 85% of callers who reach voicemail don't leave a message and won't call back. They just move to the next result on Google. Meanwhile the shops wondering why "leads have dried up" are sitting on a graveyard of ghosts — people who tried, got silence, and booked somewhere else. Leads responded to within five minutes convert at 38%. The industry average is 7.8% (Estatehub 2026 Benchmarks). That gap — 38% vs 7.8% — is entirely a response-time problem. The inquiry is the same. The customer is the same. The only variable is how fast you picked up.
Here's how the math breaks for a detailing shop specifically. A PPF inquiry isn't like a window quote — the customer has already decided they want protection film. They're not comparison shopping the concept. They're comparison shopping the shop. Your competition isn't convincing them to skip PPF; it's the guy two miles away who texted back in four minutes while your form submission was sitting in a shared inbox. Detailing customers skew toward enthusiasts who do their research in the evening — after 6pm, on their phone, while their car is in the garage. That's when the DM gets sent. That's when the web form gets filled. If your shop's response window is "business hours, next morning," you're losing a category of customer you'll never even know you lost — because they found someone else before you woke up.
Now do your own math. Pull the last 90 days. Count every inquiry that came in — every form submission, every DM, every text, every call — whether you closed it or not. That number is your lead volume. Then count how many of those became booked jobs. Divide booked jobs by total inquiries. That's your close rate. Compare it to 20%. Multiply the gap — the percentage points between where you are and where you should be — by your average job value. Now multiply that by the number of leads you receive in a month. That's the revenue you're leaving on the table every thirty days. Not annually. Monthly. Write the number down. Put it next to that blank stare you gave me when I asked about your close rate.
Same shop. Same work. Same bay. The only thing that changes is whether someone picks up.
