How would you describe the funded proposal system?

I have some understanding of what the funded proposal system is, a way of monetizing your marketing so that you get paid before someone spends a lot of money with you or joins your MLM business. How would you expand on that? I'm focusing on seminars and getting this book ready so I have something to market to people there. How would you describe the funded proposal system to someone who just wants to make money online-my clients. And knows nothing about any of this?
