Beauty salon booking software with WhatsApp reminders and automatic slot refilling
Reminders by WhatsApp are a buying criterion today because your clients already use the channel. TerminJet sends the reminder and uses that same consented channel afterwards to offer a freed-up slot to the waitlist. Booking is easy. The difference is that the gap after a cancellation does not stay empty.

WhatsApp reminders and slot refilling in one channel
A reminder in the channel your clients actually read
Emails land in the inbox and stay unread. A WhatsApp reminder arrives and gets read. Your client confirms, reschedules or cancels with a single tap, instead of calling the salon.
Freed-up slots fill themselves
If a client cancels the 4pm lash lift, TerminJet offers the appointment to the waitlist automatically, one by one via WhatsApp or SMS. Whoever says yes first gets the spot. Your treatment room stays booked, without anyone reaching for the phone.
The right time block for every treatment
Manicures, facials, HydraFacial and permanent make-up all take different amounts of time. The template stores the real duration and buffer time for each treatment, instead of forcing everything into a rigid 30-minute grid.
Online booking on your own domain
The beauty salon booking system runs online and white-label on your website, in your colours, under your name. No commission per new client, no third-party portal between you and your regulars.
An empty treatment room on Saturday is real money lost
The figures are meant as honest ranges, not as promises. What you see depends on your occupancy, treatment value and waitlist size.
- 5-15%
- of appointments fall through at short notice from cancellations or no-shows, depending on the salon
- 60-120 EUR
- treatment value that goes unused when a Saturday slot sits empty
- < 60 sec.
- until the first waitlist request goes out after a cancellation
- 0 EUR
- commission per new client, because booking runs on your own domain
How the WhatsApp reminder with slot refilling works
- Schritt 01
The client books online and gives consent
She chooses a treatment and time on your website and agrees to WhatsApp or SMS reminders when she books. The consent is documented, and unsubscribing is possible at any time.
- Schritt 02
TerminJet reminds automatically
Before the appointment, the reminder goes out by WhatsApp. With a single tap the client confirms, reschedules or cancels. That cuts no-shows and takes load off the front desk.
- Schritt 03
A cancellation triggers the waitlist
If a booking is cancelled, TerminJet contacts waiting clients through the same consented channel and offers the open slot. The first to say yes gets the spot.
- Schritt 04
The calendar updates itself
The refilled appointment lands in the calendar automatically. A gap turns back into revenue, without anyone chasing people by phone.
Why reminders and refilling belong together
Many tools only send a reminder. TerminJet uses the same documented WhatsApp consent twice: first for the reminder, then for the offer when a spot opens up. That turns one channel into real revenue protection instead of just a nice notification.

One cancellation at 2pm, two very different days
A client cancels her Saturday HydraFacial at short notice. What happens next decides whether the room stays empty.
- The cancellation comes in by phone during a treatment
- No one has time to call through the waitlist
- The slot stays empty until the evening
- 60 to 120 euros of treatment value are gone
- Reminders only went out by email and often stayed unread
- The client cancels with one tap on the WhatsApp reminder
- TerminJet asks waiting clients automatically, one by one
- The first to say yes gets the spot, and the calendar updates
- The room is booked again, the revenue stays
- The front desk never reaches for the phone once
Frequently asked questions
Are we allowed to simply remind clients by WhatsApp?
Only with consent. TerminJet collects it at booking and documents it. Clients can unsubscribe at any time. Sending and data run GDPR compliant via EU hosting.
What happens when a client cancels at short notice?
TerminJet offers the freed-up slot to the waitlist automatically, through the same consented WhatsApp or SMS channel. Whoever says yes first gets the spot, without anyone making a call.
Can the reminder go by SMS too, in case someone does not use WhatsApp?
Yes. WhatsApp is the preferred channel, SMS serves as a fallback. That way you also reach clients without WhatsApp, in each case only with their consent.
Do we have to switch our website?
No. The beauty salon booking system is embedded white-label into your existing site. The look and the domain stay yours, only the booking and reminder part is added.
Do we pay commission per new client like with booking portals?
No. TerminJet runs as your own instance on your own domain. You pay a fixed monthly price plus a one-time setup, no commission per appointment or new client.
Who sets this up?
TerminJet is set up and supported by a digital agency in Germany. We configure treatments, durations, reminder texts and cancellation rules, and embed the booking into your website.
