Larry runs a plumbing company with three trucks. His day starts at 5am, and by 7 he is already triaging email, his calendar, and whatever broke overnight.

He is good at the work. The problem is that the work keeps pulling him away from the phone.

The phone is leaking money, and most owners never see it

Across small businesses, about 62% of inbound calls go unanswered. For plumbing, HVAC, electrical, and other home-service businesses, it is easy to understand why. The owner and the technicians are holding tools, driving between jobs, or talking to the customer already in front of them.

When the next call goes to voicemail, 85% of those callers never call back. They dial the next company on Google instead.

85%

of missed callers never call back. The job does not wait for the owner to finish the current one.

Put a number on one missed service call

A single service call may be worth $275 to $1,200, depending on the trade and the job. Miss 5 calls a week and the annual service-call value behind those calls can reach $71,500 to $312,000.

That is not a marketing problem. You already paid to make the phone ring. It rang. Nobody picked up.

The only question is who answers first.

Speed matters. Industry research suggests 78% of buyers choose the company that responds first. A trained executive assistant means the answer can be your company without adding a front-desk salary, a desk, payroll taxes, and another hiring cycle.

The second cost is quieter

When an owner eventually sells a trades business, the buyer will not pay a multiple of last year’s stress. They will usually pay a multiple of profit.

Well-run plumbing, HVAC, and electrical businesses commonly trade around 5 to 11 times EBITDA, though size, recurring revenue, market, and buyer type all matter. That means every recurring cost the business removes, and every profitable job it stops losing, can be worth several times that amount at exit.

Run it the other way. Tighten the operation enough to remove $50,000 of recurring cost in a business valued at 4 times profit, and the illustrative increase in enterprise value is $200,000.

The fix is not another truck

For Larry, the immediate constraint was not demand. It was getting the office off his plate.

An assistant could own the inbox and calendar, run scheduling and dispatch in ServiceTitan, handle customer calls and texts, qualify candidates, and chase the work that used to slip. The owner could stop spending whole days rescheduling and start using those hours where only he could create value.

Start with the calls you can already count

Look at one recent week. Count the calls that hit voicemail, the web leads that waited until the next day, and the estimates that never received a second touch. Multiply only the calls that could have been real work by your average ticket.

That number is not a promise. It is a useful baseline. It tells you whether the office has become the constraint and what one dependable operator could start protecting.
