How it works
One booking. One clear trail.
Customer books
They choose a service and available time in WhatsApp or on the web.
SiniSlot checks
Capacity, payment policy, and live availability are checked again before confirmation.
Both sides get a record
The customer gets confirmation. The business sees the booking, amount, and next action.
Want to see all three steps for yourself? The sandbox opens a temporary account with sample bookings, so you can use the real dashboard and the WhatsApp booking journey without registering. It is deleted when you leave.
