If you have more than 1 office, you should create 1 account for each office. However, we can connect those accounts to merge into 1 account so you have 1 place where all your virtual tours are. Please ask support for more information if you wish to take advantage of this feature.
If you are a photographer serving many different clients then you should sign up for a photographers account. This way you get to use a different logo for each client and you can manage all your clients in 1 account.
