Ever go on a trip with a group of people and tried to equally share some of the costs? Yeah, me too. Did it all work out? Kind of. It can be a pretty big hassle trying to keep track of everything, huh? That's where Expenseus.com comes in. To quote part of their website:

      "Managing group expenses can be a social and logistical nightmare! If you are consistently spending money with the same people, you'll inevitably owe someone back, or they'll owe you. It's a hassle to keep track of all these exchanges, and when the time comes for reckoning how you stand with each other, it’s impossible to remember who owes whom, and everyone wonders if they got paid back."

Expenseus.com is an awesome web application that keeps track of all of the expenses for your group. Once everyone has entered in all of the expenses, you get a nice report showing the minimum amount of transactions needed to equal out all of the shared costs.

For example: Let's say Jimmy owes Bobby $10, and Bobby owes Suzie $10. Much of the time the transaction goes like this; Jimmy gives Bobby $10. Then, the next day Bobby gives that same $10 to Suzie. With Expenseus, the middle-man gets cut out. It knows that Jimmy should just pay Suzie $10 bucks and everything is square.

If you go on frequent group trips or consistently share expenses with the same people, this tool could be your next BFF. Best of all, the site is free to use!
