Ecommerce, many times spelled as “e-commerce”. It stands for “Electronic Commerce”. When you buy something online, typically through a shopping cart or order process, and you receive that product. That’s e-commerce. When you’re building a site, and people say, are you going to need e-commerce, that means do you need to organize and maintain products that people can purchase. E-commerce platforms typically come with payment processing and product management. Some come with inventory in the cases you have a physical product.
