Nobody logs missed calls as a cost. They don't show up in QuickBooks, they don't hit your P&L, and there's no invoice for the reroof that went to the other guy. That's what makes the leak so expensive — it's invisible by default. Let's make it visible.
The math most owners never run
The formula is four numbers you already know:
- Missed or after-hours calls per week. Count voicemails, hang-ups, and everything that rings while you're on a roof or at dinner. Most small shops guess five and find out it's more.
- How many were real leads. Not every call is a job, but a homeowner who dials a contractor usually wants something. Even conservatively, half of them are quotable work.
- Your close rate on quoted work. If you get in front of the customer, how often do you win? For most trades that's 25–40%.
- Your average job value. A service plumber and a custom builder will type very different numbers here, and both will be unhappy with the result.
Multiply it out. Five missed calls a week, a 30% close rate, and an $8,500 average job is over $650,000 a year in quoted work lost to silence — from a phone that "only misses a few calls."
The leak isn't a rounding error. For most shops it's bigger than any line item they actually manage.
"But they leave a voicemail"
Some do. Here's what the research and every contractor's own experience agree on: the caller who reaches voicemail keeps dialing down their list. By the time you call back at 7 PM, they've booked with the company that answered at 2:15. Voicemail doesn't hold a lead — it timestamps the moment you lost it.
The three leaks hiding inside "missed calls"
- The after-hours leak. Nights, weekends, holidays — when emergencies happen and offices don't answer. This is usually the biggest single share.
- The on-the-job leak. You saw the call, you were elbow-deep in a panel, you planned to call back. The lead didn't plan to wait.
- The follow-up leak. The call you did answer, the estimate you did send — dying quietly in an inbox because nobody chased it on day 2, day 5, and day 12.
Plugging the first two is about answering instantly, every time. Plugging the third is about follow-up that never gets bored, embarrassed, or busy. Both are system problems, not effort problems — which is good news, because systems are installable.
Run your own numbers
Generic statistics are easy to shrug off; your own numbers aren't. Take ninety seconds with our leak calculator and put in your real call volume, close rate, and job value. Whatever number it shows you, remember it's annual, it's recurring, and it compounds every year you leave it open.
