About Booked

Booked helps organizations and groups of all sizes efficiently manage, book, and track resources of any type. With multiple intuitive schedule views and powerful searching tools, users can quickly find available times for the resources they need. Beautifully simple calendar views allow everyone to see resource availability at a glance.

Do you have have odd schedule times or periods? Are some of your items unavailable every weekend? Does something have different hours on Mondays? Booked can accommodate any schedule you can come up with.

Administrators appreciate the vast ways Booked can be configured and managed. They can ensure resources are fairly distributed using quotas. And control usage of certain items with reservation approvals. If a reservation owner doesn't show up, Booked can automatically cancel that reservation, freeing it up for someone else. If your team needs time to set up or clean up, add an automatic reservation buffer.

Everyone is always up to date with all availability. This means no more meeting room conflicts, no more running out of chairs or laptops or whatever else your users need for a reservation. Set up a tablet next to your resource to see real time availability and allow ad-hoc reservations. Set up reminders so users don’t forget when a reservation is starting or ending.

Booked takes the stress and overhead out of scheduling so you can make the most efficient use of your limited resources. Your team can focus on getting stuff done instead of figuring out when they can get stuff done.
