Companies I've worked at make it fairly easy for me to expense a purchase, with just manager sign-off or similar. I just need some sort of up-front price for pre-approval, and a receipt afterward to send to accounting. As soon as you get any contracts involved, this becomes very difficult to get through the system. Are there open source projects out there which successfully make enhancement requests look like "purchases", rather than consulting?
