E-commerce websites are like physical stores in that they allow people and businesses to buy and sell to each other on a single platform. However, the main difference between e-commerce and physical commerce is that e-commerce transactions don't happen in person at a store. If you want to buy or sell tangible goods, digital products, or services on the website, you'll need an eCommerce website.
Whether it is bartering or buying and selling, the idea of trade has been around for a long time. No one can be on their own. Because of this, goods and services need to be in demand and sell. Transactions have been happening worldwide for a long time, both locally and across places. Keeping the same idea in mind, now think about something electronic.
