E-Commerce websites are integrated with shopping carts (or product catalogs) and highly secure payment collection systems and make it easy to sell all types of items on the Internet.
You can actually sell literally anything: products, services, subscriptions, memberships, books or downloadable items such as music, art, pictures, electronic books and so much more! You can sell anywhere from a single product to millions of products (e.g. amazon.com).
The most important aspect of e-commerce website development is to provide a great user experience and to make sure that your e-commerce website is responsive and works on all types of devices – from smartphones to tablets to laptops to desktop computers.
