Search engine major Google is aiming to wean away 90% of the Office users from US-based software maker Microsoft.

Google VP and head of Enterprise unit Amit Singh told AllThingsD: ""Our goal is to get to the 90 percent of users who don’t need to have the most advanced features of Office."

Google generates about $1bn from five businesses that sell products and services to the enterprise.

While 96% of its revenue is generated from ads, its enterprise products account for a mere 4%.

Google, however, increased its enterprise business in 2012 by launching an infrastructure-as-a-service cloud, Compute Engine: launched Drive, which allows Google App users store document in the cloud.

The search giant has also introduced the Chromebox in addition to next-generation of Chromebooks.

"This was the year where we broke the barrier and got large-scale customer adoption," Singh said.

"We know the gaps between our features and theirs. We’re improving them week by week. We’re going to get to the 90 percent."
