A CRM system, or Customer Relationship Management system, is a software tool that helps businesses manage their interactions with current and potential customers. It organizes customer information, tracks sales, and streamlines communication, allowing companies to improve their relationships and enhance customer satisfaction. By centralizing data, CRM systems enable businesses to analyze customer behavior and preferences, leading to more effective marketing strategies. These systems can also automate various tasks, such as sending follow-up emails or scheduling appointments, which saves time and increases efficiency. Popular CRM systems include Salesforce, HubSpot, and Zoho, each offering unique features tailored to different business needs.
