Private Web Stats/Analytics and Reports Tool for each vendor

We are using NopC as a selling platform for separate vendors. Is there a tool out there where I can track the stats for each vendors homepage and products. Then present a private report within each vendors admin area?

It would be nice if it was very easy to use and nice looking reports.

Whenever a vendor logs in to your site and clicks into Administration, he will see some basic statistics ...his bestsellers by amount and his bestsellers by quantity.

I know it's not what you are really wanting, but you could set up some reports in Google Analytics to be auto-emailed to your vendors on a daily or weekly basis.
Once in Google Analytics for your site go here:
in left menu >> Reports >> Behavior >> Site Content >> All Pages
In the list that appears, find the row with a vendors URL (example: /vendor-seo-title ) >> click the URL >>
.. this is the report for the traffic statistics for that vendor's home page
Near the top of the report, click the Email button, input the vendor's email address, and set up the frequency that it should be sent, etc.

There are also some good plugins for reporting
