Yes... it is called Prosper202 (free).

Prosper202 Pro (paid) uses the Google/Yahoo/MSN API to determine EXACTLY what your costs are. The free version counts on you telling the script what you will be paying on a per click basis (which you know can vary wildly). Still, the free version just requires you to do the books at the end of the day to get everything perfect.

ok thanks will check it out, still open to any other suggestions
