>Time for me to think/ask an advertiser about what he wants (i.e. ability to login and see impression/click counts, etc.) and what the CPM rate(s) should be.

The problem is often that we can't guarantee the stats like google does. (for clicks) That's why i either sell a guaranteed minimum impressions per month or a flat CPM rate.

Still track the impressions and clicks, but only as a indicator or email them reports to save the hassle of managing credentials.
