How to use groups to manage payments for your organization.
Groups are sub-categories within an organization. All the members of a group will be billed to the same payment option—so you can set one credit card for a group of people, or have another group bill their reservations to their own credit cards.
You can see and manage groups on the People page. Click on the Groups tab to take a look at your organization's groups!
This page will show you all of the groups in your organization.
To add a group, click the Add group button on the right side.
To edit a group once you've set it up, click the Edit button (the little green pen icon). From this page, you can give your group a name, manage your group members, and edit the payment settings for that group. 
Finally, to delete a group, click the Delete button (the little green trashcan icon).
