I agree with the other comments in this thread, it seems like it would be a fairly simple thing to expose the Margin (ACV) field, which already exists in the UI on the Line Item screen, to the reporting and analytics section.
We just purchased HubSpot 2 months ago, and I really don’t want to have to go the custom property route as a workaround for this, when it seems like it should be an easy fix, since the data is all there.
It also doesn’t help with internal buy-in, when we’re rolling out our beautiful new system, to have to make excuses for why things don’t work the way stakeholders expect them to.
