The basic idea behind an online drop shipping
business is that, as a small business owner, you
don’t have to maintain a large inventory (or any
inventory whatsoever) of products or handle any
delivery to your customers. That eliminates the
financial cost and risk of having a warehouse full
of stuff you might not sell, and the hassle of
arranging to send orders all over the country or
the world. In fact, you don't have to manufacture
or store any products at all.
The only thing you have to focus on is marketing
and advertising to find the customers and make
the sales. Once the sale is made the rest is
handled by others. Your only cost is the expense
of marketing and advertising to acquire a new
customer.
