Utility customer information systems (CIS) manage internal and customer-facing account operations for utility meter-to-cash processes. CIS handles customer contracts and billing against consumption data and facilitates revenue generation and collections. They support order processing, rate design, billing, payments, credit and collections. CIS includes customer self-service and communication preferences for account management and notifications. Some vendors expand to include advanced customer engagement and product and service offerings on a flexible product platform. Modern CIS is adaptable, offering deployment options from on-premises to full SaaS. CIS is central to revenue management, leveraging metered consumption data against a backdrop of service and product parameters. As utilities digitalize, CIS is evolving to encompass a broader spectrum of services, extending beyond traditional meter-to-cash processes. This expansion, often referred to as “services to cash,” necessitates innovative approaches to meet customer demands, including dynamic pricing and enhanced savings opportunities.
