I think financing is very dangerous.
I have learned that it is all a mindset. I understand that some people are responsible blah blah. From my personal studies, most successful companies that actually are in the black and actually pay taxes because they make a profit have very little money financed. I have seen the "finance mindset" bankrupt large successful companies that do good work because of a hiccup.
I think the adage that you "must have" financing to create and sustain a great business is a pre-Great Recession mindset. I keep finding myself buying these people's equipment, trucks, and hell even a house for 60-70 cents on today's value.
