Appointment businesses · 03 / 13
Booking and queue app
Customers book, move and cancel in the app, the system reminds them and fills cancelled slots from the waiting list, and the front-desk phone goes quiet.
Appointment businesses “The phone rings all day with bookings. Front-desk staff drop the customer in front of them to answer it, and people still forget their appointments.”
The problem
Almost every service business takes bookings by phone and a diary, or a diary that has moved into Google Sheets. The person at the front desk is the only one who knows what is free, so every call has to go through them. The customer at the counter waits, the customer on the line waits, and after hanging up the booking still has to be written down. Written in the wrong column, it becomes a double booking.
A customer who forgets is a slot wasted, because nobody knows they are not coming until the time has passed, and the person who wanted that slot has no way to know it was free. Reminder calls happen only in shops where staff have spare time, which is almost none.
How we solve it
We build an app that puts the diary in the customer’s hands. They see the real free times of the staff member or room they want, book on the spot, and if you take deposits they pay by PromptPay or card in the same step. The booking goes straight into the shop’s diary, the same one every branch sees.
Before the appointment, the system sends a reminder with confirm and reschedule buttons. If the customer cancels, it offers the slot to the waiting list in order, and when the customer checks in from the app it tells the staff member they have arrived. The staff screen shows the name, last service and any notes from previous visits, so the greeting is right from the moment they walk in.
Deposit refunds and moves that affect other customers still need a member of staff to confirm. The system prepares everything, and no money moves until a person approves. If a staff member calls in sick, the manager closes their diary in the app, and the system contacts everyone booked with them to choose a new time.

Who gets what
Syncs with Google Calendar or your existing queue system through its API. Deposits go through a certified payment gateway, so no card numbers pass through us, and customer history is held to PDPA rules with a log of who viewed it.
Front-desk staff stop writing bookings down from the phone, and see the customer’s name and history before they reach the door.
