PowerReviews and Salesforce have partnered so you can easily implement PowerReviews natively, within your Salesforce admin instance. This enables you to quickly start collecting and displaying ratings and reviews on your products. PowerReviews also offers the ability to collect and display questions and answers about your products and services. Depending on the package you purchased, the PowerReviews extension installs both ratings and reviews, and questions and answers.
