If you're an administrator of a Dropbox for Business account, sign in to the Dropbox website and click on Admin Console in the sidebar on the left. Then click on Account. From there, you can see the number of licenses you have left and buy more if needed.
Fortunately for administrators and storage space hogs alike, everyone on your Business account can check how much space your team has left on the Account Info tab. Just click on your email address at the top of any page and select Settings from the menu.
If you're worried about hitting your storage space limit, we want you to breathe a little easier. Simply contact us and we'll be happy to work with you to up your available space to whatever you need.
