Customer relationship management (CRM) is a crucial aspect of any successful business. It involves managing and analyzing customer interactions and data throughout the customer lifecycle. The goal is to improve customer service relationships, assist in customer retention, and drive sales growth. CRM systems compile customer data across different channels, or points of contact, between the customer and the company. These could include the company's website, telephone, live chat, direct mail, marketing materials, and social media. CRM allows businesses to learn more about their target audiences and how to best cater to their needs.
