Where is my Idealo cost data?
Funnel is unable to fetch realtime cost data from Idealo. The cost data becomes available once the current month's invoice appears in your Idealo account.
However, this delay does not affect clicks. So if you have a known CPC (cost per click), you can create your own cost metric based on Idealo clicks and your CPC. See this article for more information on how to do that.
My orders/order value in Funnel does not match Idealo
Funnel reports "completed", "revoked" and "processing" orders in separate metrics – these metrics are sometimes summed up to one on the Idealo platform.
