An estimate if none of these callers reach you. Real value depends on how many are genuine jobs.

You are open roughly 9 hours a day across 5 days. That leaves a large window each week when calls can still come in and no one is there to answer.

The calls that come when you are off the clock

Customers do not only ring during your working hours. They call on their way home, after dinner, and at the weekend, often at the exact moment a problem appears. A burst pipe at nine in the evening or a broken-down car on a Sunday does not wait for Monday morning.

For a lot of small businesses, a meaningful share of calls lands outside opening hours. This tool uses an honest assumption of around 30 to 40% and lets you adjust it. It then shows how many calls that is each week and, with your average job value, a rough figure for what is at stake if none of them reach you.

What to do with the estimate

Treat the value figure as a ceiling, not a certainty. Not every after-hours call is a job, and some callers will try again the next day. But many will not. They will ring the next business that answers, which is why out-of-hours cover so often pays for itself.

You do not have to answer the phone yourself at midnight to capture these calls. An out-of-hours answering setup can take the caller’s name, number, and job details and pass them to you, so you start the next working day with a list of real enquiries rather than a string of missed calls.

Frequently asked questions

For many small businesses, roughly 30 to 40% of calls arrive outside normal working hours: early mornings, evenings, and weekends. That is the assumption behind this tool, and you can adjust it to match your own pattern.

Because it is an assumption, not a measured fact about your business. A weekend trade sees a very different pattern from a weekday office. Change the slider to reflect when your customers actually call.

No. The point is to show the calls you cannot answer while you are off the clock. You can capture those calls with a call-back system or an out-of-hours answering setup, without picking up the phone yourself.
