CentralPlanner can be used in parallel for one or more businesses. We consider the accounts separately, i.e. the data won't be mixed at any time and also the bills will be charged separately. This also means that you have to invite the users separately for each account.
For users who work in multiple accounts we provide a convenient option to switch between accounts. If you want some of your users to have access to multiple CentralPlanner accounts, invite them with the same email address also to your second (or third ...) account. The users will see a black bar at the top of the system where all reservation books are listed.
Now one can switch between the reservation books with only one click.
Users that you invite to only one of your reservation books, have only access to this particular system.
