Abacus is already my favorite expense reimbursement app and it just got better with the addition of foreign currencies.
Now you can enter expenses in a foreign currency and Abacus will automagically do the conversion to US dollars using the current exchange rate.
To record an expense in a foreign currency, click on "USD" to the right of the amount you've entered. A drop down menu will display with some of the more common options. If the currency you're looking for doesn't show up, just start typing the name and it will appear. I haven't tested it too much, but it sure seems like all the options are there. Even Bitcoin!
This is just the sort of small improvement that can make a big difference for cloud-based businesses, which aren't limited by their location on the globe (or by fiat currencies). Now I just need a client in Tahiti to justify that travel expense...
Abacus has more details in their blog post about the new feature.
