What is the best way to implement Best Practices?

We use line status to track new business. You probably have a specific line status you use for new business right? This status is available in the production report under the Commission folder and labeled as Transaction Line Status. As for retention, i think it depends on how your agency defines retention. Do you look at the total revenue of the account, the total renewal revenue for the agency or do you consider anything that is renewed in Epic as retained.
