Google is no longer offering a free version of Google Apps for businesses.
Instead of having a choice between a free and a premium version, businesses wishing to use Google Apps now have to pay $50 per user, per year.
This version gets them 24/7 phone support, a 25GB inbox, and a 99.9% uptime guarantee.
On the upside, things won’t change for existing customers, i.e. they’ll still be able to continue using the free version.
Furthermore, Google Apps is still free for individuals, and Google Apps for Education will continue to be free for schools and universities.
