On paper, the answer is no. In practice, unless you have a fair amount of cash and tech knowledge, you should probably use an eCommerce platform.
Just consider the tech hurdles involved in launching an eCommerce store for a while. You need to build a website, host it, optimize it for SEO, optimize it for mobile users, and you need to deal with the whole rigmarole of setting up a secure payment gateway so you can accept credit cards and other payment methods. And those are just the challenges I can list off the top of my head — I’ve never attempted this project myself, and I’m sure there are other potential hurdles.
All of this is to say that there is a reason why working with eCommerce platforms is such a popular choice: a platform takes care of the technical problems for you. If you’re looking to set up an eCommerce website for your UK dropshipping business, for example, doing it yourself could take dozens of hours of work and research. While working with a platform like this one could allow you to get the job done for free in under an hour.
