Customer Community Plus is a type of Community license that should be used to meet the requirements of allowing customers to submit cases and see a dashboard of case resolution history. Customer Community Plus licenses are used for external users who access Experience Cloud sites and need to access standard CRM functionality, such as creating and managing cases, viewing reports and dashboards, or collaborating with other users. Customer Community Plus licenses are based on the number of named users and are suitable for frequent or high-value customers who need full access to Service Cloud features.
