No software can syndicate legitimate customer feedback to a Google+ profile and turn them into a rated Google+ Review. Their is no software on the market that can do that can replace a customer taking action themselves to leave a rating and a review on a Google+ Profile. 

What Rep Kahuna does is it takes that customer feedback and formats it as a post that is then syndicated to a Google+ profile and it will show up in the post/image content feed for that business.

To encourage customers to leave Google+ reviews you want to make sure you are taking full advantage of all Rep Kahuna review gathering resources; feedback pages, the mobile app, media center, request campaigns, thank you campaigns, and sign-in campaigns.
