These changes better equip the company to continue its rapid pace of product and process innovation.

In related news, Christy Ross has been named vice president of business development. She will oversee Bill.com's growing strategic relationships with software providers, resellers, and financial institutions.

"I'm very excited to announce these appointments," said Rene Lacerte, founder and CEO at Bill.com. "Mark is a proven leader with a strong sense of customer and market needs and a unique ability to bridge the gap between technology, usability, and process. Dan has done an incredible job advancing the customer service and payment operations groups, building a scalable process and delivering world-class customer service. Under their stewardship we've kept up with intense demand for new features and customer support, while preparing the company for its next phase of growth. Christy brings our organization incredible depth and experience in working with strategic software and financial markets partners. Among other things, these appointments will allow me to work even closer with our customers, accounting firms, and partners."

Prior to Bill.com, Orttung was vice president of platform and engineering for Rearden Commerce, helping the company grow to over 700 customers and more than 40 distributors, while building his team to over 100 employees. Meanwhile, Lind spent several years at Ariba before joining Bill.com. At Ariba he led a cross-functional team in the strategy, development and launch of the Ariba Supplier Network, the world's largest business-to-business procurement and supply chain network, growing it from pre-IPO to over 25,000 suppliers in 30 months.

The appointments of Orttung, Lind and Ross follow a year of tremendous growth for Bill.com, which saw monthly recurring revenue, total number of paying customers, and unique paid vendors each increase by over 800% in 2009. Meanwhile, small and medium sized business and accounting firms saved time and money managing over $500 million in bills using Bill.com, demonstrating the product's power, reliability and ease-of-use.
