An activity has one start and end time on the same day, e.g. a 1-hr drop-in art class for $25. You can also make these activities recurring, e.g. starting Apr 26 and repeating every Friday for two months.

A "series" is a group of activities purchased together, spanning multiple days (e.g., 10 1-hr music classes or a Mon-Fri summer camp).

Parties can be purchased either by a single customer (private) or made available to the general public.

Appointment schedules allow you to block off of time throughout the day that customers can then reserve. For example, you can set up 30 minute blocks of time from 9am to 1pm — customers can then choose which 30 minute block they would like to reserve.

Memberships are automatically billed according to weekly, monthly, or annual schedules that you can customize.

Class packs are multiple reservations for different events, purchased as one.

Any products you sell outside of your normal schedule, e.g. class deposits, t-shirts, etc.
