I'm an owner operator truck driver. I use dropbox mainly because its ui is the best. I take pics of my bol, payment pdf's, fuel receipts, food receipts, repairs receipts, and any other expenses I have and sync to my accounting folder which is shared with my accountant. Its just way easier to use than drive. And I get the 100 gig package for $100 a year and write it off in taxes. Win win.
