Web systems for e-commerce represent a great opportunity for companies looking to expand their business. In particular, B2C (Business-to-Consumer) e-commerce systems involve commercial transactions that take place between a company and the end customer.

The fundamental elements of a website supporting
B2C e-commerce can be summarized in the following list:

• Home page
• Category section
• Search functions
• Product catalog
• Individual product description
• Shopping cart
• Checkout process

The Home page is The company is the customer's first point of contact, therefore it is
of fundamental importance, as it must not only capture attention but
also be clear and functional for navigation, including references to the
main elements of the site.
 

Product categories have the primary purpose of making it immediately clear
what can be purchased. They can be organized through:

• navigation bar
• lists or areas

Search functions allow the user to locate a specific product.
The search interface must be simple so that the user does not feel discouraged when approaching its use. However, it should also feature search refinement features, which advanced users can enable as needed.

The product catalog aims to display all the products for sale. To catalog products, it is necessary to determine one or more classification criteria.
The classification depends on various factors, such as the number of products, the type of products, and the type of store.

The product page must provide customers with product information to help them make a purchasing decision and must provide after-sales support. It can become a full-fledged microsite, reaching up to ten pages in size and with its own defined navigation structure. The product page is discussed in detail in this post.

The electronic shopping cart is one of the fundamental components of a B2C e-commerce site, so it is discussed separately here.
