Every local business owner knows roughly what their rent costs, what their insurance costs, and what a slow Tuesday costs. Almost none can put a number on their most consistent expense: the enquiries that arrive after close and quietly die before morning.
Why don't owners notice the loss?
Owners do not notice missed after-hours enquiries because lost customers are silent. Nobody messages you to announce they booked your competitor. The enquiry either goes cold in your inbox overnight, or the customer read your site at 9pm, found no answer to their question, and left without contacting you at all.
This creates a comfortable illusion. The enquiries you catch feel like all the enquiries there are. It is the same survivorship trap we described in why the first reply wins: the losses happen out of sight, so the system feels fine while it leaks.
How many enquiries actually arrive after hours?
For most local businesses, a meaningful share of all enquiries lands outside opening hours, because customers research services when their own workday is done: evenings, early mornings, and Sundays. Check your own message timestamps and form submissions for the last month. Most owners doing this exercise for the first time are surprised how many arrived between 6pm and midnight.
How do you calculate your own number?
You can estimate your monthly cost of missed after-hours enquiries with four inputs and one multiplication:
Weekly after-hours enquiries × share lost × average booking value × 4.3 = monthly cost.
Or skip the arithmetic: our free missed lead calculator runs your numbers in thirty seconds.
The share lost is the fraction who book elsewhere if they do not hear back until morning. Given what we know about response speed, one in two is a defensible starting assumption; use one in three if you want to be conservative.
A worked example, deliberately modest. A salon gets 6 after-hours enquiries a week. Assume a third are lost to faster responders: 2 per week. Average first booking is $85. That is $170 a week, or about $730 a month, and it ignores repeat visits entirely. If a typical client returns even four times a year, the real figure is several times higher. Run the same numbers as an emergency plumber with a $450 average callout and the monthly cost clears $1,500 on one lost job a week.
Rather not do the multiplication by hand? Put your own average booking value and after-hours enquiry count into the calculator and it will give you the monthly and yearly figure straight away, using exactly the formula above.

What can you do about it tonight?
Work up the ladder from free to done-for-you, and stop at the rung where your numbers say the leak is closed.
Free, tonight: make your website answer the questions people actually ask, especially prices from and hours. Our 7-question website checklist covers exactly what to include. Then set an instant auto-reply on your socials and forms that links straight to online booking.
Low effort: keep your Google Business Profile complete and current, so the after-hours researcher gets answers before they even need to message you.
Done for you: put an assistant on your website that answers customer questions from your own information around the clock and captures the visitor's name and contact details when they are ready to book. That is what Nightshift does, and the arithmetic above is why it exists: against the numbers you just calculated, one recovered booking tends to settle the question.
Whatever rung you choose, choose one. The most expensive option on this list is the current one.
Quick answers
How do you calculate the cost of missed enquiries?
Multiply your weekly after-hours enquiries by the share likely to book elsewhere if unanswered, then by your average job or booking value, then by 4.3 to get a monthly figure. Even conservative inputs usually produce a number several times larger than owners expect.
Why don't businesses notice missed after-hours enquiries?
Because the loss is invisible. A customer who books a competitor never says so; the enquiry simply goes quiet or never arrives at all. Owners only see the enquiries they caught, which makes the caught ones feel like the whole picture.
What is the cheapest way to stop losing after-hours enquiries?
Start free: publish thorough answers and prices on your website and set an instant auto-reply with a booking link. If enquiries are valuable enough, a website assistant that answers questions and captures contact details around the clock typically pays for itself with a single recovered booking.
