Capturing expenses can be a real burden on business travelers; I personally can't count the number of times where I ended up paying for something rather than being to have a company foot the bill, simply because I wasn't able to find a receipt or didn't log an expense somewhere. JetSet Expenses (US$4.99) has been around for a while but was recently updated to version 2.1 to add new functions for helping keep your business expenses in order.
Version 2.1 has a number of updated features to make current and new users happy. First, the app now supports the larger Retina display of the iPhone 5. It's also providing support for printing expense reports (perfect for sending them to those pesky accountants) on an AirPrint printer or using an AirPrint workaround like Printopia with an older printer and a Mac.
Expense reports can now be sorted by date, either from newest to oldest or vice-versa. A function has been added to lock the expense date; all expenses added after it is locked are filled with that date until you unlock the date or change it.
Support for Google Drive and Dropbox has been updated as well. I was happy to see that with a single tap an expense report can be uploaded as a .CSV file directly to a Google Drive spreadsheet. In Dropbox, a JetSet Expenses report goes to a specific JetSet Expenses folder. The .CSV file is accompanied by pictures of any receipts that have been attached to the expense report.
