Teams are a great way to organize your users in Postal. For Business and Enterprise plans Teams can have their own Budgets, access to their own Postals in the Marketplace, and a separate Billing Account.
To add a Team:
Navigate to your Profile by clicking on your name in the top right
Find Settings on the left then select 'Users & Teams'
Select 'Teams' then select 'Create a Team'
From this menu, name your team, select the Billing Account, and determine the Budget mode.
Learn more about Billing Accounts here.
Once you've added your Team you'll want to fill it out with your Users. Learn more about adding users here.
