Choose the FTP-Stream Business Edition that meets your needs. Each plan is limited by only two factors:

Site users. That's the number
of password protected logins you can setup on the control panel. Each
login is assigned a home folder to which they are jailed when they
login so no customer will see files you have uploaded for another
customer.
In addition to the site logins you add on the panel there is
one special login – admin. This is your login. Use admin
to access the site as admin is not jailed to any folder so
can see into all the customer folders, drop files into any
folder, pick files up from any folder and move files between folders.
You manage your logins on the control panel and can delete them or
reassign them at any time. If it suits your business process you can
give the same login out to multiple people, if for example they are
working on the same project and need to share files.
There are no further limits or additional charges. In particular,
there is no bandwidth limit or bandwidth charges, and no limit to the
number of times your users can login.
If you are not sure which plan you need just make your best guess,
you can upgrade or downgrade on the control panel at any time.
