One laser device and two bookings make for a nightmare day. Set up your devices and rooms, link them to services, and let Planimore stop busy resources from being double-booked.

Changes you'll notice from the very first week, the kind that genuinely lighten your day.
Add your devices and rooms. Keep identical ones (e.g. 3 laser devices) in a single record with a quantity.
Choose which resource each service uses. Clients never pick equipment; the system reserves it for the booking.
When every unit of a resource is taken, that time disappears from the online calendar and no second booking can be added.
Lower the quantity for a device under maintenance or deactivate the resource; the calendar adjusts itself.
