Unapproved Purchases

In the past I’ve had a couple of instance where I did not approve a transaction. They were relatively small, and a clear error of the employee so I was able to get them to pay back the money. (for instance an employee paid door dash for a work event using the credit card, then didn’t change the card when she went home and ordered dinner).

Now though I’m looking to implement our broader policies and budgets into Ramp - but I’m still worried that in most cases, a big unapproved expense would still be charged to us and then internally we would have to deal with it and that employee. I was wondering how other organizations handle larger transactions that you are not approving. What happens when you don’t approve something?
