Bing conversions should be with ad click time rather than when conversion is actually recorded.
Conversions are now reported based on the time of the ad click that led to the conversion. Second, assists are now reported based on the time of the ad click that contributed to a conversion.

Importing offline rev currently works well but we can't see which search terms contributed to the revenue coming in nor the imported conversions on a search term level. Same with publisher websites - it would be useful if we could see what actual value these websites are driving in, currently we can say ok cool these websites have a good CPA and decent conv. rate but that means very little if the bottom line is not there.
The scenario/context here is lead gen/affiliate, and my specific industry is online gambling. The moment of revenue coming in is very distant to the one of the click appearing hence the importance of tying the rev back to the moment of click and associated search terms/placement, etc.
