How I can do that?

oh, sorry, I saw a wiki, but I don't remember has this explanation ...

What diference use a Contact Purchase Order Statistics Widget block, was explain in wiki, or use a workflow aggregate functionality ?

I need to know if the customer has been keeping his purchases, increasing his purchases or decreasing his purchases

I think this would be the best point to develop this, correct?
