In order for sales management to actually use the revenue reporting information to actually track sales persons' progress towards sales goals, this NEEDS to be implemented for reporting. Not having this means my sales VPs don't even bother using Hubspot to track progress on sales goals, which, in turn, means my sales people aren't nearly as diligent as they should be in tracking their deal progress and ensuring the information is accurate.
I don't really give a hoot about WHEN a contact was created. What I measure my sales people on is the amount of closed deals and associated revenue. My sales VPs can't do this if the reports only show Jan-Dec when our fiscal year is April-March.
