Online booking: rooms and equipment, no double bookings

Customers book online, day and night. Your calendar stays clean.

Zimun is an online appointment booking system for service businesses. Customers pick a free slot themselves, without a customer account. Zimun checks automatically whether the staff, rooms and equipment the service needs are available. Confirmations, rescheduling and cancellations run on their own; automatic reminders are one switch away.

Frequently asked

Common questions, answered straight.

What is Zimun?+
Zimun is a web scheduling platform that coordinates services, staff, and resources so customers can book without conflicts. It works the same way across the booking page, API and MCP.
How does Zimun prevent double bookings?+
Services can require specific staff and specific resources. Zimun locks those for the selected slot and hides times that would conflict — across every surface customers can book through.
Can Zimun book staff, rooms and equipment together?+
Yes. A service can require specific staff and specific resources: a room, a chair, a device. Zimun locks all of them for the selected slot, so a time is offered only when every part is free.
Do customers need an account?+
No. Customers book from your public page without signing up, and they reschedule or cancel through secure links in the confirmation email.
Can I use Zimun on mobile?+
Yes. The booking page and dashboards are responsive, so customers and admins can manage schedules from phones and tablets without horizontal scrolling.
Where is my data stored?+
In the EU. The platform runs on Google Cloud Platform in the region europe-west3, Frankfurt am Main. Transactional emails are sent through Mailgun's EU region, with open and click tracking disabled.
