Google Analytic Tracking Issue (&utm_nooverride=1)

[jannkuzel]

Hello,

We have a problem that means we are unable to track our AdWords and organic work at all.

Looking at "/All Traffic Sources" and clicking on "Ecommerce Tab" in Analytics we can see that (made up ratio :)):
£2 is attributed to Google/ CPC
£1 is attributed to Google / Organic
But £100 to Payment Provider/ referral and also various referrals from banking transaction pages.

All of the revenue/conversions are being credited to the payment provider or the bank security checks the payment goes through.

After having done some research we have found that the problem may be that Google Analytics attributes the purchase to the most recent click (on the payment provider button) rather than the initial click on the cpc campaign/organic or direct etc. Some people have suggested using the "&utm_nooverride=1"  
tag which we wanted to run past you guys and confirm whether adding  
this tag to the payment provider 'buy now' button on our website will  
presumably fix this referral problem? Alternatively does the tag need  
to be entered into our CPC campaigns as well? Or can you please guide  
us in another way?

We have also heard that "cross-domain" tracking could be the solution. So we are really confused what to do and where hoping someone had maybe been through something similar and could advice before we fully launch into a solution.

In addition, it should be noted that our 'Goals Funnel Visualisation'  
of 'checkout' breaks up at the penultimate stage of the checkout. All  
customers exit through the /checkout_process (penultimate) but are recognised returning to the successful checkout page but there is a missing link in between these  
two stages as 0% pass through is shown even though they do return?

Thank you so much in advance for all your help.
