Providers are entities that offer Bookable services. Often different business locations, departments, or rooms that have unique booking needs.


It’s why you use Periodic. A Reservation is made when the timeslot on a Bookable is selected and booked. Customers (and sometimes Staff) make Reservations.


Staff can add Resources to Bookables. If a Resource is connected to a Bookable, the availability of the Bookable will be further constrained by the availability of the Resource.

Resource Capacity

Setting the Resource Capacity to anything greater than 1 allows multiple, overlapping reservations on the same Resource. It’s helpful to set this to something greater than 1 when your Resource can hold more than one Reservation at a time, such as a class, teacher, or group Reservation.

Resource Groups

Allows Resources to be grouped and applied as that group to a Bookable. This also allows for various selection methods of Resources on Reservations.


Allow multiple Reservations for the same timeslot. Perfect for classes or tours. This option also allows you to define if a customer can only make a single reservation or if a customer can make multiple reservations for their friends, family members, cats, etc.

Providers and Bookables are required to have subdomains. Subdomains are the URLs Customers use to navigate to the Booking Site for a specific Provider or Bookable from their web browser. 


Add Tags that you can reference in Options and Reports. Tags will display in the Reservation data on any PDF or CSV download. 

Timeslot Selection

With the default setting of 1, set limits on how many time slots can be selected consecutively in a given Reservation. Helpful when enabling Customers to book several hours or days in a row.

Universal Mode

A Marketplace setting for Customers. When a Marketplace is set to Universal Mode, Customers are shared between Providers. Helpful to use if Customers can visit multiple locations of a business. 


The Waitlist feature exists on Bookables, allowing customers to request a Reservation even if that timeslot is taken. Administrators can turn this on when they want Customers to request timeslots already reserved.
