Most businesses require startup fees as well as a cash flow to finance the products being sold. However, affiliate marketing can be done at a low cost, meaning you can get started quickly and without much hassle. There are no affiliate program fees to worry about and no need to create a product. Beginning this line of work is relatively straightforward.
Shopify has three different account types as well as standalone third-party products like themes and apps. Commissions are paid for sales of any of these products, including users who sign up for a 14-day free trial and then convert to a paid account. Shopify also has a wide range of blog posts, webinars, and video tutorials that can be linked to with the standard commission paid on any sales that are generated.
Love the responses here. If you don't have the means to start with stock dropshipping is a good model to get into ecommerce. Its completely possible to have good margins and lots of research will help you find a better supplier. Try to keep a really good relationship with your supplier(s), add them on skype/facebook, get their phone number and treat them like a business friend!
