OSS World 2003

BOCA RATON, Fla.--(BUSINESS WIRE)--Feb. 17, 2003

Daleen Technologies, Inc. (OTCBB:DALN), a global provider of licensed and outsourced billing, customer care, event management and revenue assurance solutions for traditional and next generation service providers, announced today that the company will showcase its expanded billing and OSS products, including the RevChain(TM) billing and customer care suite, Simpliciti.net(TM) event management software, and BillingCentral(R) outsourcing solution at the Telestrategies OSS World 2003 Convention, at the Ernest Morial Convention Center in New Orleans, February 19-20, 2003. This is the company's first public demonstration of products obtained through their recent acquisition of Abiliti Solutions.

Today as a result of merger and consolidation activity, many service providers find themselves having to deal with more complex technology infrastructures involving multiple billing and OSS applications, data warehouses and a growing number of different event data streams. At the same time, economic pressures are forcing them to scrutinize their back office systems and processes, searching for ways to capture more revenue and improve overall operational efficiency. Daleen's RevChain and Simpliciti.net products are designed with flexible, performance-enhancing features that can help service providers overcome these network complexities, eliminate avoidable costs, redundancies, errors and delays, while eliminating potential revenue leaks and reducing operating expenses. RevChain leverages the latest open Internet technologies and industry standards to simplify and streamline integration with other mission critical billing and OSS applications, allowing service providers to establish a single convergent billing platform across their enterprise. Previously available only as a licensed solution, RevChain is now offered as a turnkey outsourcing solution through the company's BillingCentral ASP.

Visitors to Daleen's booth (611) will also learn how RevChain can work in combination with Simpliciti.net to help providers protect and increase their profit potential through better event management. Daleen's Simpliciti.net event management solution provides a centralized audit and control point for managing network events across an enterprise, validating and enhancing event records, and distributing them in their appropriate format to other downstream billing and OSS applications, fraud systems, and data warehouses. Its dynamic rules-driven architecture and web-based user interface give providers the flexibility they need to quickly, efficiently, and cost-effectively support new services or event data formats without complex programming. By transforming data scattered throughout the back office into a common format for viewing and reporting, Simpliciti.net also allows service providers to aggregate data across service types, conduct comparative analyses, and track trends in usage to provide valuable business intelligence.

"We're very pleased to introduce Daleen's newly expanded product and service offerings to the OSS audience," said Frank Dickinson, senior vice president of product management and marketing at Daleen. "Since launching our RevChain platform here in 2001, we've seen a dramatic increase in our customers' focus on profitability. Now in addition to the advantages available with RevChain, our Simpliciti.net and BillingCentral offerings provide even more options for improving their business performance. I encourage everyone to stop by and take a closer look at what Daleen now has to offer."

RevChain and Simpliciti.net are both available as a site license or as a turn-key solution through BillingCentral, Daleen's carrier-class outsourcing operation. Staffed by billing and telecom experts with an intimate knowledge of Daleen solutions, BillingCentral offers service providers who prefer outsourcing a high-value, efficient solution that is custom-tailored to their specific business requirements. Customers receive end-to-end support, including technical back-office support, event collection and processing, data center facilities, reports, analysis and reconciliation, invoice generation and delivery to the print vendor, and revenue assurance. With a lower up-front investment, BillingCentral gives service providers the advantage of the latest RevChain and Simpliciti.net products, rapid implementation, and guaranteed service quality from Daleen's experts, while allowing them to concentrate on their core business.
