The main difference of dropshipping in comparison with Amazon FBA is that you are selling the products without keeping the inventory and not purchasing them in advance. You simply import the supplier's product to your store, launch ads, and receive orders. Then you pay a part of your profits from the sale to the supplier, he sends the product to the customer, and you earn a margin. Thus, you do not need much money to start a business. No doubt, there still are some risks, but much lower than in other business models.
If you choose dropshipping, all you need to do is: buy a domain, choose a Shopify plan, import products, set up some apps, set an advertising budget, and start to make a profit in 3-4 weeks after you build the store.
Shopify is currently the most popular platform for work. No doubt, there are numerous other platforms with various options and features. However, in our opinion, Shopify is a platform that includes everything you need to create an online store. It allows entrepreneurs to start their own business with zero experience and minimum investment. The platform gives access to a variety of mobile-responsive themes and widgets.
