With a great interface and an even greater set of features, WhoseBill has arrived intent on becoming the standard way for people to track their every IOU from now on. This new web service can take care of tracking all that is owed, offsetting payments against each other and then settling everything up when the time comes. All that users have to do is to input what they’re paying on behalf of friends for the application to remember it all for them. The idea is that their friends will be doing exactly the same thing. WhoseBill is taking care of totaling everything up.

Moreover, users of WhoseBill can create pools with specific groups of friends, and have traditionally complex expenses (EG, arranging a club or a group holidays) dealt with in an almost instant way.
