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.

Explore how OpenSlot works
01

Your booking page, ready to share

A professional home for services, availability and the details customers need before they book.

02

Availability that works around you

Choose working hours, breaks, notice periods and time away without opening every hour of your week.

03

Payments without awkward follow-ups

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

From setup to booked

Open your calendar in three thoughtful steps.

Start simply, then add more services, staff and booking rules when the business needs them.
