You can join an existing business account on Fovira when the admin of the business account invites you to join.
Admins can send invitations to all their team members who should be added to the same business account.
The invitees will get the 'Account id' of the business account in the email invite.
Once you sign up to Fovira, you will get the option to either 'Create a new account' or 'Add to an existing account'. Select 'Add to an existing account'.
If the admin of the account invites you to a business account, you will get an email with the account id. Use this account id to join.
You will now be added to the account.
