The Best Customer Relationship Management System – Grant Cardone Dan Moore with VinSolutions talks with Grant Cardone on CRM’s, which stands for Customer Relationship Management. These systems are software that helps you keep in contact with your customers. CRM’s help you follow customers up and sell them. You want to make your job easier as a sales person, but you also want to make the customer’s experience better. You can use data to market with the right message at the right time to people rather than praying and spraying general messages out to everybody. New customers are more expensive to acquire than people you already have. The biggest mistake people make is not using the data they have.
