What a missed call actually costs an Australian service business
A missed call is not a missed conversation. It is a job that went to whoever answered second. Here is the arithmetic, using your numbers instead of a vendor's.
Johan Iskandar · 3 August 2026
A missed call costs you the calls missed per month multiplied by your close rate multiplied by your average job value. Twenty missed calls a month, a 30 per cent close rate and a A$900 average job is roughly A$5,400 a month, or about A$65,000 a year, of work that went to whoever answered instead (illustrative figures — the point is to run it with yours).
The uncomfortable part is that this is the conservative version. It counts only the job on the phone, not the repeat work, not the referral, and not the review that customer would have left.
Run it with your own numbers
| Input | Where to get it | Example |
|---|---|---|
| Missed calls / month | Your phone or VoIP call log — unanswered plus after-hours | 20 |
| Close rate | Jobs won divided by enquiries, from your CRM | 30% |
| Average job value | Revenue divided by jobs, last 12 months | A$900 |
| Monthly leakage | Multiply the three | A$5,400 |
| Annual leakage | Monthly × 12 | A$64,800 |
Two notes on honesty. Not every missed call is a new job — some are suppliers, wrong numbers and existing clients, so discount your missed-call count to the ones that plausibly represent new work. And your close rate on a call you return four hours later is not your close rate on a call you answer; it is lower, which makes the number above an understatement rather than a sales figure.
Why service businesses miss calls
Not through carelessness. The people who can answer are on the tools, under a house, driving between jobs, or already on another call. Calls arrive precisely when the business is busiest, and a large share arrive when it is closed. Voicemail does not rescue this: a caller with an urgent job dials the next business on the list rather than leaving a message.
For trades, solar installers and anyone whose enquiries spike with weather or an incentive announcement, the pattern is worse — the volume arrives in bursts, which is the exact condition a fixed number of humans handles badly.
The fix, and its payback math
Route unanswered and after-hours calls to a voice agent that answers, qualifies, books, and logs, with a human reviewing the transcripts until it is proven. What that looks like in practice, including what it costs to run, is in the AI receptionist guide for Australian SMBs.
The payback is the crudest calculation in this business: if recovered work per month exceeds the running cost, it pays for itself, and for most service businesses with real call volume that happens in the first month or two. Fixed build price and running cost are both on the pricing page so you can run the sum before you talk to anyone.
Before you buy anything, measure
Pull last month's call log. Count unanswered and after-hours calls. Multiply. If the number is small, your bottleneck is somewhere else and you should go find it — the triage in how to automate admin work will tell you where. If the number is large, you now have the one figure that makes the decision obvious, and a Foundations Session turns it into a scoped plan with the payback written down.
Questions people actually ask
Multiply the calls you miss in a month by your close rate and by your average job value. Twenty missed calls, a 30 per cent close rate and a A$900 average job is about A$5,400 of work a month that went to whoever answered. The formula matters more than any benchmark, because it uses your numbers.
Very few, and the ones who do are the exception rather than the pattern. Most callers with an urgent job simply dial the next business on the list — which is why an unanswered phone reads as lost work, not as a delayed conversation.
Because the people who can answer are on the tools, on another call, driving, or off the clock. It is not a discipline problem. Calls arrive while the work is being done, and after hours, which is exactly when a business is least able to answer them.
Route unanswered and after-hours calls to a voice agent that answers, captures the job details, books the appointment, and logs the lead — then have a human review the transcripts until it is proven. That covers overflow and after-hours without adding a salary.
Within minutes, not hours. Speed of first response is the single largest lever on whether an enquiry converts, and it is the one thing an always-on agent is unambiguously better at than a busy human.
Run the payback: if the recovered work per month exceeds the running cost of the agent, it pays for itself, and that is usually decided by call volume and job value rather than business size. Two recovered jobs a month covers a lot of automation for a business with A$900 jobs.
It wins the jobs where the caller is deciding right now — burst pipe, lockout, a quote needed before tomorrow. Those are the calls with the highest urgency and the lowest patience for voicemail, and they mostly arrive outside business hours.
