Well, just as the name already suggests, normal business usually and already has enough capital that is sufficient to carry on in its business, while start-ups may also have some capitals (but not enough capital) to finance their products, but still they have some things to be settled so as to enable them to bring their products to sell, or they may lack enough capital to render their service efficiently. In other words, a start-up may not yet have a well developed business-work-frame, just like a normal business.
