Metrics and Reporting

Id love if there was a way to calculate things the day it was actually completed rather than the day it was ordered.
Examples:
Revenue is calculated when a job is ordered rather then completed
Service performance, new clients, unique clients are all calculated on order base rather than job completion.

In my eyes, none of this should be calculated on the order date as things get cancelled and change. A new client isn’t a new client until you actually preform the media for them. Id love for there to be a way for all this to be calculated on the date jobs were completed rather than ordered.
