We have a limit to our meals as well, $80 per person. When the flag comes up, it generally nudges the expense reporter to show the breakdown of the meal - food/alcohol/tip. We also prefer itemized receipts but do not yet require them. This is due to the fact that many of our preferred hotel partners and more large businesses are pushing through level 3 data that has the breakdown on there.
We switched from travel allowance globally to actual meal expenses with a daily cap at $85 domestic / $110 overseas (USD). Travel allowance was still in place for some Countries who require that type of meal reimbursement.
The company ended up saving ~ $1 million a year on individual travel meals ~ 1500 employees expensing meals.
Thanks @jessek21 - that is a real good news story! Thank you for sharing!
