Missed Calls Are Costing Your Business More Than You Think
Every missed call is a customer who was ready to buy. Here's how to calculate what they're costing you, and the three ways to stop losing them.
Most owners know they miss calls. Almost none know how many, or what those calls were worth. So the problem stays abstract, and abstract problems don't get fixed.
Let's make it concrete.
Do the math for your business
Pull up your phone system or your call log for last month and count the calls that went unanswered or to voicemail. If you can't get that number, estimate: most small service businesses miss between a quarter and a half of incoming calls during working hours, because the person who answers is also the person doing the work.
Say it's 40 calls a month.
Now, of the calls you do answer, what share are new customers or new jobs, rather than existing customers or suppliers? For most businesses it's around a third. So roughly 13 of those 40 missed calls were potential new work.
Of new inquiries, how many normally become jobs? If you close half, that's about 6 jobs.
What's your average job worth? If it's $800, that's around $5,000 a month walking away. If it's $3,000, it's closer to $20,000.
Adjust the numbers for your business. Whatever you get, that's what missed calls cost you every month, and it's usually more than any software you'd need to fix it.
Why voicemail doesn't count
People don't leave voicemails anymore, and they especially don't leave them for a business they've never used. They hang up and call the next name on the list. The customer who reaches voicemail isn't waiting for you to call back. They're already talking to someone else.
Why "I'll call them back" doesn't work either
Even when a customer leaves a message, calling back an hour later means calling someone who's already booked with a competitor, or who's now busy and doesn't pick up. Now you're playing phone tag with someone who was ready to buy an hour ago.
Speed is the whole game. The business that answers, wins.
Three ways to stop losing them
Text-back on every missed call. The simplest fix. When a call isn't answered, the caller immediately gets a text: "Sorry we missed you. What can we help with?" Many will reply, and a text conversation can book the job. This recovers some of the loss and costs almost nothing.
A person whose job is the phone. Effective, but expensive, and only during their hours. Calls at 6 p.m., on weekends, or during lunch still go to voicemail. Most small businesses can't justify a full-time receptionist for the volume they have.
An AI receptionist. Answers every call, every hour, in a natural voice. Takes the caller's details, answers common questions, books the appointment into your calendar, sends the customer a confirmation, and texts you a summary. It never puts anyone on hold and never misses a call because it's on another one. For most small businesses this recovers nearly all of the lost calls at a fraction of the cost of a person.
What it changes beyond the revenue
When every call is answered, two other things happen. Your existing customers stop feeling ignored, because they get through the first time. And you stop carrying the phone as a constant interruption, because the calls that reach you are the ones that need you.
