Accretive Commerce Selects CyberSource as its Global Payment Processor.

CyberSource and Accretive Commerce form Strategic Alliance to Enable Multiple Payment Options and Advanced Fraud Protection for Accretive's Clients

CHARLOTTE, N.C. & MOUNTAIN VIEW, Calif. -- Accretive Commerce, the leading business process outsourcer of direct-to-customer commerce services, announced today they have formed a strategic alliance with CyberSource Corporation (NASDAQ: CYBS), a leading provider of electronic payment and risk management solutions, to offer CyberSource's payment management services to Accretive Commerce's clients.

Accretive customers will now be able to accept online credit card, debit card, eCheck, PayPal, and Bill Me Later transactions. They will have the ability to accept orders originating from 190 countries, verify addresses, calculate sales tax, and check orders for compliance with export regulations. Accretive Commerce's clients will also have the opportunity to utilize CyberSource's risk management services. These offerings range from fully-managed services to advanced decision systems that automate order screening, helping to increase sales conversion and reduce the risk of fraud. Finally, merchants will also be able to protect their brand by using CyberSource's token-based secure storage service, which helps keep sensitive payment data out of merchants' daily business operations.

"Consumers are increasingly looking for alternative methods of secure online payment, while merchants need the latest in risk management to reduce their exposure to fraudulent activity," said Hank Reeves, Accretive Commerce CEO. "CyberSource's services offer market-leading capabilities in both areas, and we believe Accretive Commerce's clients will be well served through our relationship."

"Accretive Commerce, like CyberSource, has significant experience serving some of the biggest brands in eCommerce today," said Carolyn Brackett, vice president, channels & alliances, at CyberSource. "We believe this alliance will provide Accretive with an even more complete end-to-end outsourced eCommerce solution, including global payment and risk management capabilities, further enhancing an already successful offering."
