The short answer
For a med spa, the first reply often decides the booking. In a study of web leads, calling within 5 minutes rather than 30 made reaching the lead about 100 times more likely, and Harvard Business Review found firms that replied within an hour were nearly seven times as likely to qualify a lead as those that waited an hour longer. Because many enquiries arrive in the evening, an AI receptionist that replies in seconds protects bookings that would otherwise go to a competitor.
Key takeaways
- Interest in a treatment fades within minutes, not days: speed decides who gets the booking.
- Many beauty and spa bookings are made while businesses are closed, often in the evening.
- Every enquiry answered too late is a treatment’s worth of revenue walking to a competitor.
- An AI receptionist replies in seconds, books consultations and hands medical questions to your team.
When do people look for aesthetic treatments?
Mostly when your clinic is closed. People research treatments on their phones in their own time, and for most that means the evening.
- In Thailand, internet users spend an average of 7 hours 54 minutes online a day, 5 hours of it on their phones (Digital 2025 Thailand, DataReportal and Meltwater).
- Nielsen found Thai smartphone users chat most from 6 to 9pm, with social media peaking again at 8 to 9pm (Nielsen Thailand, reported by The Nation, 2016). In the Philippines, Nielsen saw smartphone activity peak from 6pm to 11pm (Nielsen, 2014).
- Booking data from more than 5,000 salons and spas showed 46% of appointments were booked while the business was closed: 28% in the evening and 18% before opening (Phorest data, reported by HJi, 2019).
So the moment someone decides “I want to ask about that treatment” is very often 9pm on a sofa, on LINE, WhatsApp or Instagram. If nobody answers until 10am, the moment has passed.
How fast does a lead’s interest drop?
Fast. The two best-known studies of response time both show interest falling within minutes and hours, not days. They measured different things, so they are shown separately here.

The same Harvard Business Review audit of 2,241 US companies found that only 37% replied to a web enquiry within an hour, 24% took more than 24 hours, and 23% never replied at all. The average reply, among companies that did respond, took 42 hours (as reported by SmartCompany). That gap is the opportunity: most competitors are slow.
What does one missed enquiry cost a med spa?
At least the value of the treatment they wanted, and often far more. A client who books a $300 treatment and loves the result comes back, buys follow-up sessions and refers friends. Lose the first reply and you lose all of that to whichever clinic answered first.
Calculator: what slow replies could be costing you
Bookings at risk each month: 15 · Revenue at risk: $4,500 a month, $54,000 a year
Formula: enquiries × share answered late × share that would book × treatment value. Use your own numbers: the defaults are an example, not an industry average.
Change the numbers to match your clinic. Even small gaps add up: if a handful of evening enquiries a week go unanswered until morning, that is a meaningful share of your monthly revenue. See what an AI agent costs to compare.
How quickly do customers expect a reply?
Within minutes. Messaging has become the default way to contact a business, and the expectation of speed has come with it.

| 73% of US med spa regulars are more likely to choose a med spa they can reach 24/7 | Zenoti survey, 2025 (a software vendor’s US survey) |
Put simply: if your competitor replies on LINE in a minute and you reply tomorrow, most people will already have booked with them.
How does an AI receptionist stop the leak?
It answers every enquiry in seconds, day or night, from information you have approved, and moves the conversation towards a booking.
- Replies instantly on LINE, WhatsApp, Instagram and your website chat, in English and Thai.
- Answers treatment questions about what a treatment involves, downtime, starting prices and how to prepare, using your own wording.
- Books the consultation straight into your calendar and sends a reminder.
- Hands anything medical to a person: suitability, side effects and complaints go to your team with a summary.
- Follows up with people who asked but didn’t book, so warm leads don’t go cold.

Questions
How fast should a med spa reply to an enquiry? +
Within minutes. Research on web leads found the odds of reaching someone fall sharply between 5 and 30 minutes, and replies within an hour were far more likely to turn into qualified leads.
When do most med spa enquiries come in? +
Often in the evening, when clinics are closed. Booking data from thousands of salons and spas found nearly half of appointments were booked outside opening hours.
Can an AI receptionist give medical advice? +
It should not. A well-built AI receptionist answers general treatment questions from your approved information and hands anything about medical suitability, side effects or complaints to your team.
How much revenue does a med spa lose from slow replies? +
It depends on your enquiry volume, booking rate and treatment prices. Use the calculator above with your own numbers: enquiries × share answered late × share that would book × treatment value.
How much does an AI receptionist cost? +
At PJW Partners, AI agents start from $1,000 USD for one agent on one channel, and most go live in 2 to 3 weeks.
