WhatsApp Business is a specialized communication platform designed to help small-to-medium businesses (SMBs) professionalize their customer interactions. By integrating business-specific tools—such as automated messaging, product catalogs, and in-app payment capabilities—into the familiar WhatsApp interface, the app lowers the barrier to entry for digital commerce. Targeted at SMB owners who need to streamline support and sales, the app occupies a dominant position in the Business category. Its primary differentiator is the seamless fusion of a globally ubiquitous messaging platform with enterprise-lite features like conversation labeling and Meta Verified authenticity.
