An account can be in multiple Organization at the same time.
For example, if you:
- work for a company;
- do freelancing;
- and build your own company at the same time;
You can be in all 3 Organization at the same time, saving you lots of time from logging in for each of them repeatedly.
Whenever you create a new organization, you will be assigned as the super admin for that space.
Payment information is also assigned to Organizations, not individual users.
