PRSFE Portal Software (MM)

Product Quality and Company Relationship Key to Customer Approval; Company Calls for Industry Transparency into Customer Satisfaction Portal Software, Inc. (Nasdaq:PRSFE), the premier global provider of billing and Revenue Management solutions, today announced the results of its semi-annual customer satisfaction survey. The survey, conducted by TNS Prognostics, a global leader in customer research-based consulting, found that more than 85 percent of Portal customers using versions of Portal's platform version 6.2 and greater intend to repurchase -- or upgrade to -- newer versions of the Portal platform. (Note: version 6.2 was available to customers beginning in December 2001.). Respondents cited product quality and Portal's relationship as the main drivers of their intention to repurchase. "Portal's platform approach allows us the agility, stability and scalability to capture new revenue and market opportunities as we identify them," said Joost Eringfeld, head of Billing Domain at Swisscom Mobile. "We see Portal not merely as a technology vendor but rather as a mission-critical partner in maximizing our revenue relationships." While customer surveys are more common in mature industries such as hardware, operating and database systems, Portal believes it is time to gather, monitor and communicate customer satisfaction levels in the billing and Revenue Management market. "With this announcement, Portal is definitively taking aim at the billing industry's Achilles heel -- customer satisfaction," said Paul Hughes, director and senior telecom analyst at Yankee Group. "As convergence becomes more and more of a business reality, billing and revenue management solutions will be increasingly critical to providers' competitive strength. As a result, customer satisfaction, along with time-to-market and functionality, will emerge as the key differentiators for revenue management solutions." In February, Portal announced the availability of Portal 7, a single platform that enables service providers to manage revenue on any type of network: real-time IP and circuit-switched, fixed and mobile, voice and data. The Portal 7 platform integrates and optimizes every stage of the Revenue Management lifecycle: revenue generation, capture, collection, and analysis. With Portal 7, service and content providers are able to deliver services that are optimally priced for their businesses, customers, and partners. Portal 7 ensures all transactions are captured, rated, discounted, and charged, and that bills are generated accurately and revenues collected. "Customer satisfaction in this market has historically remained a low priority -- sacrificed for the sake of customization. With the advent of product-based solutions, customers should not be required to sacrifice satisfaction for functionality," said Dave Labuda, CEO of Portal Software. "We fundamentally believe that today's hyper-competitive telecommunications market demands that carriers and content providers evaluate their billing and revenue management solutions through a lens similar to that of a CRM or ERP system, where customer satisfaction is a key metric." Methodology TNS Prognostics, a global leader in customer research-based consulting, surveyed 225 technology support, business owners and executives representing 120 Portal customers. The survey was conducted online from February 23-March 11, 2005. Portal has measured its customers' satisfaction at 14 intervals over the past eight years in an effort to enhance its products, services and support programs. About Portal Software, Inc.
