Newbie question about tracking sales on pay per click

I've tried Overture Pay Per Click for the last month now but the thing that strikes me is I have no way of tracking sales per keyword. I have affiliate software which *could* do this but it would mean an affliate account for each keyword/phrase which would be ludicrous bearing in mind I am experimenting with about 20 to 30 keyword phrases and possibly looking at other Pay Per Click engines. Is there a recommended script that will do this (free or otherwise). What I'm looking for is software/script that will tell me Overture made a total of X in Y month, with a breakdown of each keyword/phrase sales. Any suggestions?

Categories

PPC engines can be categorized in "Keyword", "Product", "Service" engines. However, a number of companies may fall in two or more categories. More models are continually being developed. Currently, pay per click programs do not generate any revenue from site traffic to sites using these programs. Only when visitors click on banner advertisements or pop-ups is revenue generated.
