As an administrator of the account, you have the ability to grant access to or remove users from your organization.
From your Admin page, click users, and then select Invite User.
Here you can enter an email address for the user to invite them to your Order Manager. You can enable them to create orders, view all orders, or both. You can also choose to allow this user to have Admin privileges by assigning them as an admin through Role.
Removing Users from Order Manager and Organization
When viewing the list of active users on the users screen, you can remove a user by clicking the trash icon located to the right of their name.
