A customer portal is a self-service online platform that allows customers to access essential services such as support, order tracking, account management, and knowledge base resources. These portals improve customer experience by offering 24/7 accessibility, reducing the need for direct customer service interactions. Businesses integrate customer portals into their CRM systems to streamline communication, provide personalized support, and enhance customer engagement. Features often include live chat, ticket submission, product documentation, and payment management. Industries like e-commerce, SaaS, and banking use customer portals to empower users with self-service options, reducing operational costs and improving response times.
