Towngas has historically been the sole supplier of town gas in Hong Kong, serving over 1.4 million households. However, the gas industry now faces increased competition. Towngas implemented a customer relationship management (CRM) framework in the 1990s to achieve competitive advantage, focusing on customer service. Key aspects of the CRM framework included a costumer focus team, total quality management, and an enterprise customer management system. This approach helped Towngas maintain over 45% of residential customers and led to increased sales growth and customer retention despite industry challenges. The document recommends further strengthening Towngas' CRM approach through improved customer data and processes, expanding product offerings, and generating new business lines.
