Why your guess is wrong in a predictable direction
Ask any tradesperson how many calls they missed last month and you will get a number between two and five. Ask them to open their call log and count, and the number is usually several times that. The gap is not carelessness. It is structural, and it comes from a simple fact: the calls you remember are the ones that turned into something.
A missed call from an existing customer resolves itself. They ring back, or you ring them, and it enters your memory as a conversation rather than a miss. A missed call from a stranger does not resolve. They ring someone else, that business does the job, and nothing about the transaction ever reaches you. There is no complaint, no follow-up, no gap in your week. The only evidence is a number in a log, and nobody scrolls back through a call log.
So the calls that cost you money are precisely the calls that leave no impression. Your memory is not sampling randomly — it is systematically excluding the expensive ones.
The calls you remember missing are the ones that cost you nothing. That is why they are the ones you remember.
Counting them properly, in about ten minutes
You do not need software for this. Every phone and every carrier keeps the record already.
- On an iPhone, open Phone, then Recents, then tap Missed. On Android, open Phone, then Recents, and filter to missed. Both keep enough history to cover a month for most people.
- For a landline or a business line, log into your carrier account and download the call records for last month as a CSV. Every major Australian carrier provides these.
- Count the unanswered inbound calls for one full month. Do not exclude anything yet.
- Now go through and mark the numbers you recognise — existing customers, suppliers, family, your accountant. Those are your low-cost misses.
- What is left is the number that matters: unanswered calls from numbers you do not know. Every one of those was somebody who wanted something and did not get it.
- Check how many of them rang once and never rang again. Those are the ones who definitely went elsewhere.
What each one is worth
The instinct is to multiply the count by your average job value, and that is wrong in both directions. Not every missed caller would have booked — some were price-shopping, some were selling you something, some were ringing the wrong number. Equally, some were worth ten average jobs, and some would have become repeat customers for a decade.
A more useful framing is this: you do not need to know the average. You need to know whether the number of genuine, unrecognised, never-rang-again callers is greater than zero on a typical month, and what one of them is worth to you. If you missed six strangers last month and one job is worth more than a year of any tool you might use to catch them, the maths is already settled and precision does not change the answer.
The pattern in when they arrive
Sort your missed calls by time of day and a shape usually appears. For trades it is generally two humps — mid-morning once people are up and dealing with whatever went wrong, and late afternoon once they are home and reminded of it. Both of those are times you are on the tools.
That timing is the part worth sitting with. It is not that you are bad at answering the phone. It is that your customers ring at exactly the hours your work makes answering impossible, and no amount of discipline changes that. The problem is a scheduling conflict, not a personal failing.
What the research says, and what it does not
There is very little Australian data on this, and a lot of quoted statistics that trace back to small or old studies. Two figures are worth knowing, both from CallRail’s 2025 survey of 1,000 US consumers: around 82% said they would call a competitor if their call went unanswered, and only around 42% said they leave a voicemail.
Those are US consumers, not Australian ones, and a survey of stated intention is not a record of behaviour. Treat them as directional rather than precise. The more widely circulated claim that 62% of calls to small businesses go unanswered traces back to a 2016 study of 85 businesses, which is too small a sample to carry the weight people put on it.
This is why counting your own calls beats every statistic on the internet. Your call log is a census of your business, not a sample of somebody else’s.
What to do with the number
If your count of unrecognised, unanswered, never-rang-again callers is genuinely zero or one a month, you do not have a missed-call problem and nobody should sell you a solution to one. Spend the effort on getting more calls instead.
If it is more than that, you have a choice between three things: answer more calls, which usually means interrupting your work or hiring someone; accept the loss as a cost of doing business; or reply automatically so the caller is held until you are free. Which of those makes sense depends on your volume and your margins, not on anything a website tells you.
