You're on a job. Phone rings. You're up a ladder or elbow-deep in a hot water system. You let it ring out. No big deal, right? They'll call back if it's urgent.

Except they don't call back. They ring the next sparkie in their search results. And that single missed call just cost you anywhere from $400 to $2,500 in revenue you'll never see again. For most Australian tradies, missed calls aren't an inconvenience - they're the single biggest leak in the business.

The real numbers behind missed inbound calls

Let's start with what we know from industry data. According to BIA/Kelsey research, 85% of callers who can't reach a business won't call back. They move on. For trade services where the caller has an immediate problem - blocked drain, no power, aircon dead in summer - that percentage climbs even higher.

Now look at your own call log. If you're running ServiceM8 or similar job management software, pull your missed call report for last month. Most plumbers we've spoken to are running at 20-35% missed call rates during business hours. Electricians sit around 25-40%. HVAC techs often higher again during peak summer.

The maths gets ugly fast. If you're getting 40 inbound calls a week and missing 30% of them, that's 12 lost opportunities every single week. Multiply that across a year and you're looking at over 600 jobs you never even quoted on.

What's an average job actually worth?

This varies wildly by trade and job type, but let's use some realistic Sydney metro figures. A typical emergency plumbing callout - blocked drain, burst pipe, leaking tap - averages $450-800 once you factor in callout fee, labour, and parts. Electrical work runs similar for basic jobs, higher for switchboard or rewiring work. HVAC service calls often start at $300 for a diagnostic, then climb to $1,200-2,500 if they book a system replacement.

For this worked example, let's be conservative and use $650 as your average job value. That's below what most ServiceM8 users report, but it keeps the numbers realistic.

Here's the calculation:

• 40 calls per week coming in
• 30% missed (12 calls)
• 85% of those 12 won't call back (10 lost jobs)
• 10 jobs x $650 = $6,500 in lost weekly revenue

That's over $25,000 per month walking out the door. For a sole trader or two-person outfit, that's often more than the total monthly revenue they're actually banking.

The callback myth

Most tradies convince themselves they'll return missed calls during smoko or at end of day. And sure, you do call some back. But by then the customer has usually already booked someone else. The job we listened to last Tuesday was a perfect example: blocked toilet at a rental property, property manager needed it sorted same day. Called four plumbers. The one who answered first got the job. The other three got voicemail.

Even when you do reach them on callback, you're now competing. When you answered immediately, you were the solution. When you call back three hours later, you're an option they're comparing against the bloke who's already on his way.

What this costs over a year

Using the same conservative numbers:

• $6,500 lost per week
• 52 weeks = $338,000 annual revenue gap
• Even if you only count 45 working weeks (holidays, sick days), that's still over $292,000

Now factor in repeat business and referrals. A customer you never spoke to can't become a repeat client. Can't refer you to their neighbour. Can't leave you a Google review. The lifetime value of that missed call compounds fast.

For context, most trade businesses operate on 15-25% net margins after costs. So that $292,000 in lost revenue represents roughly $44,000-73,000 in actual profit you didn't take home. That's a ute. A second van. A full-time apprentice. Or just a decent chunk of your mortgage paid down.

What to do about it

You've got three basic options. One: hire someone to answer calls. Expensive, and they're not on the tools. Two: keep missing calls and accept the loss. Three: automate it.

An AI receptionist picks up every call in under two rings. Books the job straight into ServiceM8. Sends the customer an SMS confirmation. Takes payment details if you want. Handles basic questions about your rates and service area. Never calls in sick. Costs less per month than you're losing in a single day of missed calls.

The setup fee at VoxReach is $5,500, and inbound calls run from $0.42 per minute. For most tradies, that investment pays for itself in the first month just from recovered jobs. Sign up free at app.voxreach.com.au/signup - you get 30 minutes of calls to test it with real customers before you commit to anything.

Or keep missing calls. Just know exactly what it's costing you.
