Data analysing software - do you have any recommendations?

I were wondering if someone knew of some sort of programm / script to look at someones feedback and break it down to what they have sold and what period, maybe you could set it to 6 months or so, what they have sold and how many.

Just a little spy program

Want to spy on my supplier.

Hi T0pSales,

Sorry but I can't think of anything at the moment. If I do come across one, I'll be sure to let you know.

Cheers :)
