Awaiting guidelines, but as far as i am aware, the individual is responsible for their receipts, and as an imprest holder you are not required to do any of that stuff over and above the standard hotel receipts you used to do. The difference is that if someone has not spent their entitlement, you have to collect any unspent dosh. Someone else will address the receipt issue I guess.
What was wrong with the old system though?
Now I might have to spend some of my own hard earned cash on enebriation.....
