In LivePlan, you can create as many new "Companies" as you like. A Company is basically a container, which holds all of these features:
With each new Company you create, you'll have access to create fresh versions all of the above.
There isn't a limit to the number of Companies you can create in your account. But in the default account, there is a limit to how many of your Companies can be active at one time. An active Company is a company that's available for editing, and for sharing with collaborators. Companies that aren't currently active are stored in your archive. Keep in mind that you cannot edit or print content from a Company while it is archived.
It's easy to switch between Companies in your account, archiving one and making another active. For more on creating Companies and switching between them, read Managing your companies and plans.
If you'd like to have more than one active Company in your account, you can upgrade. For more on this, read Changing the number of active companies on your account.
