CRM software stands for Customer Relationship Management software. It's like a computer program that helps businesses keep track of their relationships with their customers. It can be used to record information about customers, like their names, addresses, phone numbers, and what they've purchased before. It also helps businesses stay in touch with customers by sending emails or texts with updates or special offers. By using a CRM, businesses can make sure they're staying connected to their customers and improving the overall customer experience.
