I’m no business-travel scofflaw. But I get plenty of automated emails not-too-subtly nudging me to do my expenses already. I’ve had more than a few expense reports returned for missing receipts or other missing details. Adjusting to new rules in a new job that has me crisscrossing the country more than ever is part of the reason. Mostly, though, I—and millions of others—need to do a better job of corralling receipts and filing reports as soon as possible after a trip so they don’t pile up.
