Managing expenses is only a pain because my company doesn’t trust me when I tell them I spent $20 on a meal. And have to give them both a digital, and then physical (signed!) receipt.
But none the less, all company expenses needs to be verifiable by some kind of receipt in the accounting to be legal. At least thats how it works in my country. So someone has to enter that into some sort of system, ideally the economy people would take care of that.
