Advantages of Google Apps Premier/for Business

Main page for differences

• More than 50 users (more than 3000 for U.S. non-profit other than schools). Starting from May 10th 2011, the upper limit for the free edition will move from 50 to a meagre 10!
• Mail advantages
• Triple the amount of mail storage (one can still buy more, but it will be on an individual basis and will be shared with all services instead of being limited to the mail)
• Mail redirection handling
• Mail support (even phone support for service unavailable emergencies)
• Extra mail control (Postini, mail quota, mail blacklist (inbound only))
• Much easier migration (from Outlook or Lotus, for instance)
• Shared addressbook (in practive, works very badly without a third-party addition)
• Some advanced mobile device management
• Login advantages
• Single Sign On (SSO)
• Password complexity tuning
• No ads
• User-managed forums and mailing-lists
• Access to Google API

How much does Google Apps cost?

As usual with Google poor documentation, it is not easy to have definitive answers.

Pricing for Google Apps

Edition	Pricing	Eligibility	Notes
Standard	Free	Everyone	Compared to personal account, addded value is minimal or even negative
Non-profit	Free	U.S., up to 3000 users, comply with some part of the U.S. law.	Beyond 3000 users, Premier with a 40% discount (40 $/year/user; there is no price in euros or pounds since Non-profit is only for the U.S.). Hopefully a complete feature set (contrary to Education), whatever the amount of users, but no evidence so far. Not to be mistaken with Google for non-profits
Education	Free	U.S. school
Business/Premier	50$/user/year (40€ or 35£; doesn't change with exchange rate).	Everyone	This starts from user #1, not user #51 (I have to check this, though). So, if you are 50 users using Google Apps Standard, think twice before upgrading!
