Missed Calls Are Revenue Loss

If you run a barbershop or salon, phone calls are usually high-intent. People don’t call “just to browse.” They call because they want availability and they want to book.

And in barbershops and salons as well (as many other small businesses), if you don’t pick up, a lot of callers don’t patiently wait — they just try the next place. That’s the real reason missed calls turn into missed-call revenue loss so fast.

Why callers don’t call back (especially for barbershops and salons)

When a business doesn’t answer, callers don’t all wait around.

According to CallRail, when businesses don’t answer:

21% of consumers immediately call another business
24% switch to online chat
42% leave a voicemail

Source: CallRail survey summary

That “call another business” behavior is exactly why barbershops and salons get hit so hard. The customer is ready now, and switching is easy.

Voicemail isn’t a safety net

A lot of owners assume: “If it’s important, they’ll leave a voicemail.”

But voicemail behavior has been declining. CBS News reported (citing Vonage data) that about 80% of callers don’t bother leaving voicemails. Source: CBS News on voicemail decline

Even if your business gets some voicemails, the bigger problem remains: many callers won’t wait for callbacks. They’ll just book elsewhere.

The ROI formula is simple

Here’s the easiest way to estimate missed-call revenue loss:

Lost revenue = missed calls × booking rate × average service value

Where:

missed calls = inbound calls × missed call rate
booking rate = how many callers would have booked if you answered
average service value = your average ticket

CallRail reports that, on average, 28% of calls to businesses go unanswered. Source: CallRail missed call rate

Example math for a barbershop vs a salon (CZK)

Let’s use real public prices so this stays grounded:

Barbershop example: “Classic haircut” listed at 699 CZK. Source: Barbershop Urban pricelist
Salon example: women’s cut + wash + blow-dry listed from 1,400 CZK. Source: Trichomania pricelist

Now assume a shop gets 20 inbound calls/day.

1. Missed calls/day 20 × 0.28 = 5.6 missed calls/day Source for 0.28: CallRail missed call rate

2. Booking rate For a conservative benchmark, Nextiva cites that 37% of digital marketing leads convert on their call. Source: Nextiva on missed calls

(For barbershops and salons, the real booking rate from calls can be higher because callers are often ready to book — but we’ll keep it conservative here.)

3. Lost bookings/day 5.6 × 0.37 = 2.072 bookings/day

4. Lost revenue/day

Barbershop: 2.072 × 699 = 1,448.328 CZK/day
Salon: 2.072 × 1,400 = 2,900.8 CZK/day

If you want a simple “per month” estimate (26 working days):

Barbershop: 1,448.328 × 26 = 37,656.528 CZK/month
Salon: 2,900.8 × 26 = 75,420.8 CZK/month

Again, the exact numbers will vary, but the model is the point: in high-intent industries, missed calls leak revenue every single day.

The hidden cost nobody counts: missed calls steal time from paying customers

This is what makes the problem so frustrating in service businesses:

You’re with a client (who is literally paying for your time), and the phone rings.

If you pick up: your current client is paying for that interruption with their time and experience.
If you don’t pick up: the caller often books somewhere else.

I lived the same tradeoff when I taught golf lessons. Mid-lesson, someone calls to book. If I answer, I’m stealing time from the person in front of me. If I don’t answer, I might lose the next client entirely.

Barbershops and salons have this problem all day.

What you can do today (without hiring anyone)

1) Measure your missed calls for 7 days

Count:

inbound calls/day
missed calls/day
when they happen (peak hours, evenings, weekends)

Once you see the number, the ROI becomes obvious.

2) List the top 10 caller questions

Most calls cluster around:

“Do you have availability today?”
“How much is X?”
“How long does it take?”
“Where are you / where do I park?”
“Can I reschedule?”

The faster these are answered, the fewer interruptions you have while working.

3) Stop relying on voicemail as plan A

How Switchly.ai helps you never miss a call without hiring

Switchly.ai is built for exactly this problem: high-intent callers + busy service providers.

It can:

answer calls instantly (including after-hours)
handle multiple callers without busy signals
handle booking based on available slots (so you don’t create calendar chaos)
answer FAQs and policy questions in natural language
and if there’s truly a rare edge case it can’t solve, it transfers the caller to the phone number you choose

From an owner’s perspective, the win is simple: You don’t have to choose between your current client and your next client.

The bottom line

In barbershops and salons, missed calls are rarely “maybe later.”

Often, they’re “someone else today.”

If you want to stop losing bookings without hiring, start by treating missed calls as what they are: measurable revenue loss — and a workflow you can fix with Switchly.ai.
