You pay for Receptive per team user, depending on your plan.
Team Users are people in your organization that you invite to access Receptive.
Team Users can (depending on their permissions) submit and prioritize their own feedback, view and manage incoming requests, vote and prioritize on behalf of customer users, and look at Receptive's reports to understand the value of different requests.
Prices per team user vary depending on the plan you choose. Pricing is available here.
