BILLMONK

Because borrowing money from friends can be "awkward", BillMonk keeps track of all your friends' IOUs and debts so you don't have to remind them that they owe you. BillMonk is a social money management tool that allows a group of friends to keep running tabs on who owes who how much and for what. Users collaborate online deciding how to split past and current bills such as taxi fares or restaurant bills. BillMonk calculates how much you owe (or are owed) and then lets you pay online or by mob... ile phone through parent company [obopay's](http://crunchbase.com/organization/obopay) payment services. With obopay, BillMonk users can record bills on their account immediately after getting them by sending a text message to BillMonk. This feature will save those of us who loose receipts or forget how much we owe even before the night is over.Mobile (and online) payment integration is the killer app and differentiating feature for BillMonk, as competitor [Buxfer](http://crunchbase.com/organization/buxfer) lacks any type of payment tools and [Wesabe](http://crunchbase.com/organization/wesabe) does not have a mobile payment option. Both competitors offer a product more in tune with Quicken that helps you to understand how you spend your money through trend analysis and data visuals. BillMonk focuses solely on helping you pay and receive money from friends and settling informal debts. In addition to monetary debts, Billmonk can track things you borrow or loan to friends like a movie or a jacket even. A useful tool, BillMonk also enjoys being one of the first companies to tap the [$103 billion](http://money.cnn.com/2006/07/10/magazines/business2/mobilecommerce.biz2/) market of social money traded each year. BillMonk has a [Facebook](http://crunchbase.com/organization/facebook) [application](http://facebook.com/apps/application.php?id=2218471450&b) in addition to its mobile and browser products.More
