You're under a sink with both hands busy. The phone buzzes in your pocket and stops. You finish the fitting, wipe your hands and look: a missed call from a number you don't know, no voicemail. You think, if it's serious they'll call back.
The one real line the system we run has answered since August isn't a plumbing shop, but its callers behave the same way: they aren't calling to chat, they're working down a list.
So here is what that one call costs. Not a dollar figure we invented. The real pieces, and where each number comes from.
ServiceTitan looked at call data from more than 3,000 trades businesses. Shops with fewer than five techs booked 24% of their calls. Shops with 25 or more techs booked 59%.1 Same trade, same kind of caller. The difference is that the big shop has someone whose whole job is the phone, and the small shop has you, under a sink.
Time of day makes it worse. For the small shops, the booking rate went from 26% at its best to 9% after 6 pm.1 Those are the hours you're driving home, eating, or asleep.
Invoca, which tracks calls for home service companies, found that 27% of calls to home services businesses are not answered at all.2 More than one in four. If you think your number is lower, count for a week. The method is at the bottom.
A missed call isn't one loss. It's four.
The obvious one. CallRail asked 1,000 U.S. consumers what they do when a business doesn't pick up, and 82% said they'll call a competitor.3 For a plumbing call that means the next shop on the map. You don't lose a lead. You hand it to the guy across town.
Same survey: 78% said they have abandoned a business after an unanswered call.3 Not the job. The business. A plumbing customer is worth years of calls if you keep them: the water heater in three years, the remodel, the call from their mother. The first unanswered call ends all of that before it starts.
Nobody recommends the plumber who didn't answer. The shop that picked up gets the "who did you use?" at the barbecue. There's no study for this one. You already know it's true.
The cost nobody counts. You get home, sit down and start calling back numbers. A lot of them don't pick up, because people screen calls from numbers they don't recognise: 87%, in a ZipWhip survey that Numa's roundup cites.4 The ones who do pick up have already booked someone. You spent your evening confirming losses.
Ask people and they say they do. In CallRail's survey, 42% of consumers said they leave a voicemail when a business doesn't answer.3 Watch what they actually do on a home services line and it's different: Invoca measured less than 3% of callers pushed to voicemail leaving a message.2
That gap is the whole story. People believe they'd leave a message. Then the recording starts, and they hang up and dial the next number. It matches what we hear on the line we run: people talk to a voice that asks them a question. They hang up on a beep.
The easy answer is "get someone on the phone". Most small shops can't. The Bureau of Labor Statistics expects about 42,000 openings a year for plumbers, pipefitters and steamfitters over the decade, and describes the work as full time, including nights and weekends, often on call for emergencies.5 Every hand you have is billable and tired. Pulling a tech off jobs to sit by a phone costs more than the calls.
The same page says the trade is growing 7% from 2025 to 2035, much faster than the average job.5 More demand, same number of hands. The phone problem gets worse before it gets better.
Don't take our figures or anyone's. Do this for one week:
That's your real cost. And if the ServiceTitan pattern holds for you, the evening calls are the ones least likely to have been booked.1
We run an AI receptionist for home service shops (plumbers, HVAC, roofers and others). She only answers when you don't: your line forwards to her after you miss the call, and if you pick up, nothing changes. She answers in your shop's name, gets the caller's name, number, what's wrong and how urgent, in English or Spanish, and texts it to you the second the call ends. Calls that aren't a lead wait for one summary in the evening.
We set it up and we run it. Nothing to install, nothing to learn. She has been answering a real business line since August.
If you take one thing from this: the caller who hangs up on your voicemail is not calling back. Whatever picks up instead of the beep is what saves the job.

Your phone rings first, and only the calls you miss go somewhere useful instead of voicemail. What conditional forwarding is, how Verizon, AT&T, T-Mobile and business phone systems handle it, and the tests to run once it's on.
The three ways a small shop covers the phone when nobody can pick up, judged on one thing: what happens to the caller. With the numbers, and the honest downsides of each, including ours.
