buxfer.com

I have been using buxfer.com for over a year and a half to track my personal expenses, but the best part of the software is to settle shared expenses. Each person involved in the transaction is a different buxfer user. Each time you make a shared expense for home, say splitting money for lunch, all you do is to enter the amount, how much each person owes and thats it. Every one involved in the transaction gets an email informing them about the expenses. Its basically a sophisticated excel sheet to track common expenses. My roommates and I have found it to be very useful tool. The website has a wide variety of analysis tools and can give you an idea of where to cut down the expenses. Another nice thing is that you do not need to sign up if you have an AOL, Facebook, Openid, google, yahoo or msn username, which makes the sign up process significantly easier. I think its a great tool for personal and shared expenses.
