Depends on how burned your boss has been. For a while finance departments just paid invoices without question. It was a lot cheaper than what we have now. Then someone in finance did an audit of a routine invoice (a random thing to show a junior how it could be done if requested) and discovered the "services rendered" on the invoice was just sending an invoice - no other work was being done. Now the company spends a lot of money to carefully verify every invoice is for real work done. It might cost more money in the long run but it doesn't feed fraud.

The above might be an urban legend, but it is still a good story.
