The main purpose of Customer Relationship Management (CRM) is to enhance interactions with current and potential customers, improving satisfaction and loyalty by centralizing customer data and enabling tailored marketing efforts. In contrast, Lead Management focuses on effectively capturing, tracking, and nurturing potential customers throughout the sales process, prioritizing leads based on their likelihood to convert and guiding them through the sales funnel. Together, CRM and lead management create a cohesive strategy that optimizes customer relationships and drives business growth.
