My company is a broker in the real estate industry. As such, we send a lot of our listings to sites like Trulia.com and Zillow.com, among others. These sites direct leads to our realtors, and provide us with reports every month detailing the activity our listings have had on their site-- links back to our website, emails generated, etc.

Our Marketing and Advertising departments want to take that information and enter it into a system to keep track of everything in one place, for the purpose of producing comparison reports.

I cannot find any externally available product that provides this functionality. I would sincerely like to avoid writing this tool myself. Does anyone know of a tool that could do this?

In short, an ideal system would:

• Imports Google Analytics data via API
• Imports real estate listing site data via CSV import / manual entry
• Provides comparison reports based on data

Does anyone know of anything pre-made that can do this?
