Unlike starting a business with physical products, selling digital products is less expensive and requires less work. You don't have to pay extra manufacturing, shipping, or maintenance fees with your online business. Once you purchase your product (or create it yourself) and build your website, all that's left to worry about ismarketing your digital products and generate the most profit.
With the low cost required to start, selling digital products offers you a PASSIVE income stream. This means that once you do the work once, you could never touch it again and you could still be making sales. When you purchase a DFY digital product, the work is already done for you! You are allowed to resale and duplicate those products as much as you like to make the most sales.
