@kdfrawg There are corporate expense solutions like Concur and Nexonia. The apps aren't the problem per-se, as they basically allow me to do my expense report "as I go" which helps tremendously.
The issues I have are correlating activities on my credit card statement to entries on my expense report. It really doesn't help that Citi lumps all the "foreign exchange fees" into a single charge that doesn't even show up when I log in online.
It would also be nice if the website wouldn't try to automatically adjust the exchange rate on a particular entry AFTER I've already set it manually.
