When you set up your account, you can set up the ways you want to be able to submit expenses. You can send them in via Jott, Twitter, email and more. You just send something like "Taxi 30 to airport” or something, and your expenses will be entered into your online account. Then you can download them in a number of formats to complete your expense reports. You can also take pictures of your receipts and email them to your Xpenser account for safe keeping.
 
This service is in beta, which means it’s still free. It won’t be for long.
