How Much Are Missed Calls Costing Your Trades Business?
Most trades owners underestimate missed calls because they never see them add up. One here, two there, a few on a busy Monday. But every missed call is a potential job, and many callers do not leave a message. They just call the next company on Google.
Here is a simple way to work out what missed calls are costing your business, and what you can do about it. If you would rather skip the maths, use our free Missed Calls Calculator.

The four numbers you need
- Calls per week. Your phone system or provider can usually tell you this.
- The share you miss. Calls that go to voicemail or ring out: when you are busy, on the tools, at lunch, after hours and on weekends.
- How many of those callers would have booked. Not every caller is a job. Be honest and conservative.
- Your average job value. Take it from your invoices for the last few months.
A worked example
Take a business that gets 100 calls a week, misses 20% of them, would have booked 30% of those callers, and has an average job of $450. These are example numbers. Put in your own.
- 100 calls x 52 weeks = 5,200 calls a year
- 20% missed = 1,040 missed calls
- 30% would have booked = 312 lost jobs
- 312 x $450 = $140,400 a year
Even if you halve every assumption, the number is rarely small. And that is before counting repeat business: a customer who books you once for a furnace repair often comes back for maintenance and the next replacement.
Where trades businesses miss calls
- On the tools. Owner-operators and small crews cannot answer with their hands full.
- Peak hours. Monday mornings and the first cold or hot spell of the season, when everyone calls at once.
- Lunch and breaks. The office is one person, and that person needs a break.
- After hours and weekends. Often the most urgent calls, and the most valuable.
The hidden costs on top
- Wasted marketing. If you pay for Google Ads or directory listings, a missed call is a lead you paid for and then lost.
- Call-back time. Returning voicemails, playing phone tag and re-asking questions takes hours every week.
- Reputation. “Couldn’t get hold of them” is a common theme in low-star reviews.
How to stop losing them
There are three common fixes, in rough order of cost and effort:
- Call-back discipline. Return every missed call within minutes. It helps, but it depends on someone always being free, which is the problem in the first place.
- An answering service. A person takes a message. Better than voicemail, but someone still has to re-enter the details and call the customer back.
- An AI receptionist. Every call is answered at once, day or night. The JobPerfect AI receptionist recognises returning customers and books the work straight into BigChange, Simpro or Jobber. After hours, it is powered by CallRoster AI and gets real emergencies to your on-call tech.
