A CRM (Customer Relationship Management) system focuses on managing a company's interactions with current and potential customers, enhancing customer service, sales, and retention. It tracks customer data, communication history, and sales activities. Conversely, a CMS (Content Management System) manages digital content creation, editing, and publication for websites. It facilitates content organization, collaboration, and version control without requiring technical expertise. While CRM optimizes customer interactions, CMS streamlines content management.
