After-hours calls: the hidden revenue most businesses are leaving on the table

A significant share of calls to local businesses happen outside business hours. Almost none of them get answered. Here's what that costs — and how to fix it without hiring anyone.

30 January 2026

Most small business owners think of their phone as a business-hours tool. The phone rings during the day, staff answer it, appointments get booked. After 5pm, it goes to voicemail.

The problem is that customers don't stop calling at 5pm.

When people actually call

Call data from Turnless businesses shows a consistent pattern: a significant share of inbound calls — often 20–30% — happen outside standard business hours. The peak after-hours window is 5pm to 8pm on weekdays, when people have finished work and are thinking about the things they need to sort out.

For trade businesses, there's also a meaningful volume of calls on weekends and early mornings — people who've noticed a problem and want to get it sorted before the week starts.

These calls don't get answered. They go to voicemail, or the caller hangs up when they hear the voicemail greeting. Either way, the business doesn't know the call happened, and the revenue opportunity disappears.

The invisible cost

The reason most business owners don't worry about after-hours calls is that the cost is invisible. You don't see the calls you didn't answer. You don't know how many people called at 6:30pm, got voicemail, and booked with a competitor instead.

But the maths is straightforward. If your business misses four calls a week outside business hours, and each call represents a potential booking or job worth $200, that's $800 a week — or roughly $40,000 a year — in revenue that never appeared on any report.

For businesses with higher average job values — plumbers, electricians, HVAC — the number is significantly higher.

Why voicemail doesn't work

The standard response to after-hours calls is voicemail. But voicemail has a fundamental problem: most people don't leave messages.

Research consistently shows that voicemail response rates have declined sharply over the past decade. Younger customers in particular are unlikely to leave a voicemail — they'll hang up and try the next business, or look for an online booking option.

Even when customers do leave voicemails, the callback often happens the next morning — by which point the customer may have already booked elsewhere, or the urgency has passed.

What actually works

The businesses that capture after-hours revenue have done it by making sure every call gets a real response, regardless of when it comes in.

Turnless answers calls 24/7 in a natural voice. A customer who calls at 7pm gets the same professional experience as a customer who calls at 10am. The AI handles the conversation, books the appointment or captures the job details, and notifies the business owner by SMS.

For reception businesses — salons, dental practices, allied health — after-hours callers can book directly into the next available slot. For trade businesses, the AI captures the job details and flags urgent calls for immediate attention.

The customer gets a response. The business gets the booking. The revenue that used to be invisible shows up.
