Aria Systems and Rackspace Team to Provide On-Demand Billing for SaaS Industry

The relationship links two experienced SaaS vendors and reinforces Aria Systems' emerging position as standard for SaaS-based transaction management. To-date, Aria Systems has managed more than one million accounts with its customer care and self service tools, billed customers in 236 countries with its advanced localization features, configured and maintained 8.2 million plans and services, and automatically rated more than one billion usage units. Companies powered by and partnering with Aria include Flagship Studios, DigitalBridge, ZoomInfo, OpSource, Serena, Xythos, Marketo, Auran Games and TransFirst.

"Rackspace, like its customers and others across the industry, realizes that billing is more than simply issuing invoices and processing payments," said Edward Sullivan, founder and CEO, Aria Systems. "They see that doing business in an on-demand world is changing. They see products being reformulated into subscription-based services and expectations of real-time interaction between providers and their customers growing rapidly. And when they look at their operations, they see an untapped opportunity to drive more value from each customer interaction."

Aria Systems' approach to billing encompasses the full lifecycle of a company's recurring relationship with its customers. Its billing engine leverages the benefits of SaaS - no infrastructure to manage, no software to install, faster time-to-value and simple subscription pricing - all of which enable Rackspace's hosting customers to optimize their own SaaS delivery.

"An application is just an application until the right business tools and processes are in place to generate revenue," said Scott White, director of channel sales, Rackspace. "We believe that Aria Systems gives our customers one of the easiest, most cost-effective and powerful tools to turn applications into revenue-generating businesses."

Rackspace delivers a diverse suite of enterprise-class hosted IT services, integrating the industry's best technologies and delivering them as services.
