The Accounts Health dashboard allows a user to analyze revenue realization, length of relationship, and customer lifetime value across accounts. Revenue realization is the actual revenue as a percentage of planned revenue. Length of relationship is the duration between today and the start date of the first sales agreement with an account. Customer lifetime value is the total of revenue generated to date and revenue anticipated from the account. These metrics help the user to assess the performance and potential of each account and identify opportunities for growth or retention.
