Some business strategies like those espoused at a famous group based in Australia calls for 0 investment. But for downpayment (as in software of house projects) then progress billing. However when the principal is dishonest, he can run away with the downpayment or splurge on it for other luxuries not the project completion Or future cash flows based on on promos or membership
But things can go wrong and they will always go wrong at the most inopportune time. And the principal cant meet his obligation. And then he becomes a scammer.
Or sometimes the local laws and on environment: a typhoon or earthquake turned against him/his business.
