How Much Is a Missed Call Really Costing Your Plumbing Business?
A simple formula for what missed calls actually cost your plumbing business per week, per year — and why fixing it usually costs less than a single lost job.
Most plumbing business owners have a rough sense that missed calls hurt. Few have actually run the numbers. Once you do, the amount of money quietly walking out the door every month is hard to ignore.
The Simple Formula
The math only needs three inputs: how many calls you miss in a typical week, what share of those would have turned into a booked job, and what an average job is worth. Multiply it out and multiply by 52 weeks, and you have your real annual cost.
Missed calls per week × booking rate × average job value × 52 = annual cost of missed calls.
Running the Numbers for a Typical Oahu Plumber
Take a plumbing business missing 3 calls a week — a conservative number for a single-truck operation during busy season. If even half of those would have booked at a $300 average ticket, that's 1.5 jobs a week walking away. Over a year, that's 78 jobs and more than $23,000 in lost revenue.
Bump the missed calls to 5 a week, which isn't unusual for a two- or three-truck crew, and the number climbs past $39,000. At a higher average ticket — water heater replacements, repipes, larger repair jobs — the same call volume can mean $46,800 a year or more, which is the exact math worth sitting with: 3 missed calls a week at a $300 job value adds up to that number by itself.
Why It's Actually Worse Than the Math Shows
The formula above only counts the job you didn't book. It doesn't count what that customer was worth over time. A homeowner who called for a repair and got no answer doesn't just skip that repair — they also skip the maintenance plan, the water heater replacement in three years, and the referral to their neighbor. First-call losses compound.
It also doesn't count reputation. A caller who couldn't reach anyone doesn't usually leave a bad review — they just never become a customer, and you never know they existed. That's revenue with no paper trail, which is exactly why most business owners underestimate it.
What Fixing It Costs
Compare that lost-revenue number to what it costs to stop it. A part-time receptionist runs well into four figures a month before payroll taxes, and still can't cover nights and weekends — exactly when trade businesses miss the most calls. A generic answering service is cheaper but still requires you to call the customer back before they call someone else.
An AI receptionist built for trade businesses, like Solid Kine, answers every call around the clock, books the job or texts you the details immediately, and typically costs less per month than the value of a single missed job. For most Oahu plumbing businesses, covering the gap costs less than what one recovered job is worth.
Do the Math for Your Own Business
Pull up your call log or just estimate honestly: how many calls do you think go unanswered in a normal week? Multiply that by half, then by your average ticket, then by 52. Whatever number you land on is money currently going to whichever competitor picks up the phone first.
If you want help running that number for your specific business, Solid Kine offers a free walkthrough that shows what an AI receptionist would have caught in your actual call volume — no contract required to see it.
