Business plan pricing is based on the number of active users.
A user is anyone using your Kudoboard system, regardless of whether they are a board creator or simply a contributor. Contributors are those who post on boards. Board recipients who do not create boards or post on boards are not considered users unless you have proactively added them as a user or they have registered as a user.
Click the person icon in the upper right corner of the page.
