Mobile app should have a way to import pdf receipts from drop box.
I use concur as well as Expensify. For concur I can send the pdf directly from my email to the app. I have encountered problems email pdf to Expensify app and it take a bit of time. I figure If concur can do it Expensify should be able to make this functionality. The only work around I have found is to take a screen shot which for multiple page pdf doesn’t work.
