What one missed call really costs a service business

Most owners think of a missed call as a small annoyance. Run your own numbers and it usually turns out to be the most expensive thing that happens in the business all week.

Start with your average job

Take your last month of invoices and divide total revenue by the number of jobs. For a lot of plumbers, HVAC techs and electricians that number lands somewhere in the hundreds of dollars, and the big jobs, like a water heater, a panel upgrade or a new system, run into the thousands. Write your number down. That is what a caller is worth when they become a customer.

Then ask what happens when nobody answers

Think about the last time you called a business and got voicemail when you had a leak, a dead furnace or a car that wouldn't start. Most people don't leave a message. They go back to the search results and call the next number. The caller who reaches a person first usually gets the job, even if the price is a little higher.

So a missed call from someone who needs help now isn't a delayed job. It's usually a job that went to someone else.

Count how many you miss

Pull up your phone's call log for one week and count the calls you didn't answer during working hours, plus anything that came in at night or on the weekend. Don't count spam. Be honest: every call that came in while you were on a ladder, under a sink or driving counts.

Do the math

Missed calls per week, times the share of them that were real jobs, times your average job value, times 52. Even with cautious numbers, say two real jobs a week at your average ticket, the yearly total is usually far more than any answering service costs.

That doesn't count the repeat business and referrals a new customer brings, which is often worth more than the first job.
