Watch it work
From a new service to a booking in the diary.
A quieter way to stay booked
Your diary shouldn’t depend on a trail of messages.
When every appointment starts with “What times do you have?”, the admin grows quickly. Details get buried, gaps appear and follow-ups take over the day.
OpenSlot puts your real availability in one clear booking page. Customers choose a suitable service and time, while you keep control of what can be booked.

Request a deposit or full payment during booking, with booking and payment status kept distinct.
