First off, selling online is a simple concept at its core. It\\'s all based on you showcasing your products (or services) somewhere online, and letting people buy those products (or services) right then and there. Notice that I\\'m saying \\"somewhere online\\" and not \\"on your website.\\" As surprising as this might sound, a website is not required to sell online. All you need is to list your offering \\"somewhere\\" (like on someone else\\'s website, a social media platform, and, yes, your own site as well), and then have tools in place that would allow people to buy the thing from you. To be fully honest with you, however, having an online store website will certainly open up more opportunities and allow you to reach a wider audience.
