Once you get into a bureaucratic loop (like this job sounds like), plan on waiting forever for your money. I've seen invoices bounced for checking the wrong box on 1 of 18 forms. Once that got fixed, it travelled further up the pipeline until it got kicked out because the forms as submitted were stapled together in the wrong order (I'm not kidding).
Generally everyone in the bureaucrat chain is trying to do their job right, but nobody looks at the big picture. They just want the invoice off their desk; it makes no difference to them if it gets kicked further up the chain or kicked out the door and right back to you.
