What Is an E-commerce App?
An e-commerce app is a mobile application that enables businesses to conduct commerce electronically over the Internet — allowing companies to sell products or services directly to customers through their smartphones and tablets. Beyond simply providing an online storefront where customers can browse products and complete purchases, a well-built e-commerce app typically includes a broader suite of business-critical features.
