Aria Systems, Inc., the only provider of enterprise class Billing and Customer Management Software as a Service (SaaS), announces the opening of its new office in San Mateo, CA. The expansion is due to growing demand for Aria’s services and represents the latest in a series of milestones in 2009. Despite the economic downturn, Aria has grown and thrived in 2009. Aria consistently wins against on premise and on-demand competitors and is being selected as more companies expand and additional industries consider using Billing in the Cloud.

In addition to its core customer base in SaaS and Media, Aria has expanded its product to service new industries including renewable energy utilities, insurance companies and cloud service providers. Having grown 10X in the past year, Aria now serves up in excess of 10 million transactions around the globe each month.

Also, Aria Systems has announced several partners that have become proficient at deploying and integrating its Subscription Billing platform. The Aria professional services partners have enabled Aria to scale rapidly and deploy more customers globally.

"The economic downturn has been a catalyst for accelerating SaaS adoption," Said Edward Sullivan, Aria’s CEO. "New companies and industries are now beginning to see the clear advantages of leveraging the Cloud."
