<prompt> Human: I work for a billion dollar publicly traded company. If I have to travel for work, I pay for my expenses, then file the receipts and get reimbursed.When I worked at much smaller companies, I would also pay the expenses up front they would advance the money if needed, so maybe it is similar at all companies.Is this the standard, most common method of managing expenses?  <response>: In my experience, yes. You pay, you file your monthly expense report, you get reimbursed.
