Something that slightly worries me is the premise, but I' m sure somebody will understand better than me.
I work in construction on the financial side and you would never pay for material/stock off site unless you have a very good reason and if you do you are taking a big risk that it doesn't disappear if the company goes bust, etc.
How do they insure that the goods are as claimed and will be passed to the funder if the company goes down?
