What a missed call actually costs a trade business

A missed call is the only business expense that never appears on a statement. No invoice, no line item, no direct debit. It just quietly does not happen, and the money goes to whoever picked up instead.

That makes it easy to ignore, and easy to overstate. Plenty of people selling answering services will quote you a frightening industry statistic. We would rather show you the arithmetic and let you put your own numbers in, because the answer varies enormously by trade and the honest version is more useful than the scary one.

The four numbers you need

Everything turns on four figures you already know, or can find in about ten minutes.

1. Calls you miss in a week. Check your phone. The missed-call log is right there, and it is usually a worse number than people expect, because it includes the ones during a job, during a drive, and after five.
2. How many were new work. Not suppliers, not the bank, not your mum. For most trades this is somewhere between a third and half of missed calls.
3. How many of those you win when you do answer. Your own close rate on inbound enquiries. If you have never measured it, most trades sit somewhere between one in two and one in four.
4. What a job is worth. Average job value, not your best month.

Then multiply the four together.

A worked example

Take an electrician missing eight calls a week. Say three of those are new work, they win one in three of the enquiries they actually speak to, and an average job is £320.

Eight missed, three new, one in three won, £320 a job. That is one job a week, or roughly £16,000 a year of work that rang out.

Run it again for a business with a lower job value and fewer missed calls — four missed, one new, one in four, £140 — and you get under £2,000 a year. Still real money, but not an emergency.

That spread is the whole point. The number is not a constant. It is worth an hour of your time to work out which end of it you are at, because the answer decides whether you need to do anything at all.

Half the value of this calculation is discovering you do not have a problem. The other half is discovering you have a large one.

Voicemail is not the answer, and everyone already knows it

The standard advice is to make sure calls go to voicemail. In practice, most people ringing a trade for the first time will not leave one. They are standing in a kitchen with water coming through the ceiling, and the next number on the search results is right there.

The three things that genuinely move the number:

• Somebody answers. A person, a service, or a machine — the caller does not care much, as long as they get an answer and a time.
• A missed call gets a reply fast. A text back within a minute, with a booking link, recovers a surprising share of what rings out. Not all of it. But this is the cheapest intervention available and almost nobody does it.
• The answer can actually book. An answering service that takes a message and emails it to you has moved the admin, not removed it. You still ring back, you still find a slot, you still write it in the diary.

Where this gets uncomfortable

Here is the part that answering-service salespeople skip: if your missed-call number is small, none of this is worth paying for.

A £79-a-month answering service costs about £950 a year. If your arithmetic came out at £2,000 of lost work, and the service recovers half of it, you have spent £950 to make £1,000. That is not a business decision, that is a rounding error with paperwork.

At £16,000 of lost work, the same £950 is obviously worth it. The reason to do the calculation is to find out which of those two businesses you are.

What we built, and when it is not for you

Bizzle Phone is an AI receptionist: it answers, it knows your services and your hours, it books into your actual calendar, and it texts back the calls it could not take. It costs £29 a month with a hundred minutes included, and it is included in the Team and Growing plans.

It is a good answer if you are missing real work every week and you would rather not pay a person to sit by a phone that rings six times a day.

It is the wrong answer if you miss two calls a week and both were the same supplier. Do the multiplication first. If the number is small, spend the £29 on something else — and if you want to see what the arithmetic looks like across your whole admin bill rather than just the phone, we wrote about what the back office actually costs.
