Rivly allows the creation of multiple roles by admin users in order to invite other users to participate in your organization with varying levels of permission. Examples of this could be for an accountant or customer service agent. To learn more about the different types of user roles possible within a single seller account, please check out our article user roles and permissions.
If you are a user that has been given access to more than 1 seller account with your single login, you will have the ability to change between the various seller accounts by clicking the seller name in the horizontal menu at the top of the screen. This will provide you with a dropdown list of available seller accounts.
