How many calls is your business actually missing?

31 July 2026 · 6 min read

Most owners have a gut feeling about missed calls. Very few have a number. The gap matters, because a feeling can't tell you whether to change anything, and a number usually can. Here is a way to find yours in two weeks, using tools you already have.

Why a number beats a feeling

When you're on a roof or under a sink, a missed call feels like a small thing. It rings out, you get on with the job. By Friday you've forgotten it happened.

But missed calls tend to cluster. They happen when you're busiest, which is also when you're least likely to ring back the same day. A tally shows you the pattern: how many, at what times, and on which days. That's the information you need before you spend a penny on fixing it.

What you'll need

Nothing you don't already own. Set aside ten minutes to get set up, then a minute a day after that.

• Your mobile call log. Both Android and iPhone let you filter to missed calls. That's your main source.
• Your landline voicemail, if you have a landline. Note the time each message was left, not just that it exists.
• Your phone provider's online account, if your plan includes call records. Some do, some don't. Worth a look, because it catches calls that never showed on the handset.
• A notepad or a single spreadsheet. One row per missed call. Nothing fancy.

The two-week tally

Two weeks is long enough to smooth out a freak quiet spell and short enough that you'll actually finish it. Pick two ordinary weeks. Not the week you're on holiday, not the week after a storm.

Each evening, open your missed calls and log anything from that day. For each one, write down four things:

1. The date and time.
2. In-hours or out-of-hours (your hours, whatever they are).
3. Whether you rang back, and whether you got through.
4. What it turned out to be, if you found out — new enquiry, existing customer, wrong number, sales call, or unknown.

Why the in-hours and out-of-hours split matters

These two piles have different causes and different fixes. In-hours misses usually mean you were on another call, driving, or elbow-deep in a job. Out-of-hours misses mean nobody was there at all — evenings, early mornings, weekends, lunch.

If nearly all your misses are out-of-hours, the problem is coverage. If they're spread through the working day, the problem is that you can't be in two places at once. Both are solvable, but you'd approach them differently, and you can't tell which you've got without the split.

Clean the list before you do any maths

This is the step most people skip, and skipping it is how you end up with a scary number that isn't true. Go through your two weeks and cross off:

• Repeat dialers. Someone who rang three times in four minutes is one enquiry, not three.
• Wrong numbers.
• Sales and spam calls. You'll recognise most of them.
• Existing customers with a query. Still worth answering, but not new revenue.
• Calls you rang back and won anyway. Those aren't lost. They cost you time, not money.

What's left is your pile of possible new enquiries that never reached you. That's the only pile worth doing arithmetic on.

Now do the maths — with your own figures

Here's a worked example. A plumber finishes the tally and, after cleaning the list, has 12 unanswered new enquiries across two weeks. That's 6 a week. He reckons roughly 1 in 4 enquiries turns into work, and his average job is £180.

6 × 1/4 = 1.5 jobs a week. 1.5 × £180 = £270 a week. Over 48 working weeks, that pattern would come to £12,960.

Now change the assumptions and watch what happens:

Same method, very different answers. That's the point. Put your own three numbers in and you get a figure that's actually about your business.

What your split is probably telling you

Once you've got two weeks of data, the read is usually straightforward.

• Mostly out-of-hours, low in-hours. You're fine during the day. You just aren't reachable when people happen to think about their boiler, which is often in the evening.
• Mostly in-hours. You're busy, which is good news. The fix is about handling overflow while you're on the tools.
• Low in both, and you already ring back same-day. You may not have a missed-call problem at all. Spend your attention elsewhere.
• High in both, clustered on particular days. Look at what happens on those days. It may be a scheduling issue rather than a phone issue.

When you might reasonably do nothing

Not every business needs to change anything after this exercise, and it would be daft to pretend otherwise.

If your tally comes back with two or three genuine missed enquiries a fortnight, and you ring them all back within the hour, the honest answer is that your current system works. If you're already booked out for three months and turning work away, extra enquiries aren't a benefit — they're more admin.

Some trades genuinely don't run on the phone. If most of your work comes from a merchant's recommendation, a builder you sub for, or repeat customers who text you directly, then your call log isn't where your business lives. Audit the channel that actually matters instead.

And if you have someone in the office answering the phone properly, you may find the tally simply confirms that. Good. That's a useful thing to know for £0.

If the number does bother you

That's what we built RedAgents for. The AI receptionist answers calls 24/7 in your business's name, books jobs, sends quotes, and sends you a WhatsApp update after every call, so you always know what was said. You keep your existing number — nothing about how customers reach you changes.

Setup takes about 60 seconds from your website URL. There's a 7-day free trial with no credit card, and plans start from £29 a month. Nothing reaches a customer without your approval, which matters when it's your name on the van.

But do the tally first. Two weeks, a notepad, one minute a day. Whether you end up changing anything or not, you'll stop guessing — and you'll know exactly what you're deciding about.
