Selling goods and services online can net significant income, provided you can set aside time to manage your online business. Remember, when you sell a physical product to an online customer, you are responsible for shipping, whether doing it yourself or partnering with a dropshipper. You must also maintain an up-to-date inventory and comply with all relevant tax laws. If you have the bandwidth for this, you may find that you love selling online—particularly when you can do so from the comfort of your home.
