Avalara Reaches Impressive Software-as-a-Service Milestones - Sales Tax Automation Goes Mainstream.

1,000 Businesses Using AvaTax[TM], the Leading End-to-End Web-Hosted Sales Tax Solution; More Than 21,000 Customers Utilizing Avalara Services

BAINBRIDGE ISLAND, Wash. -- Avalara (www.avalara.com), the leading provider of Web-service based sales tax automation solutions for small and mid-sized businesses, today announced that it has met the 1,000th mark of businesses using its AvaTax[TM] solution, while more than 21,000 customers utilize the innovative and affordable solutions offered by Avalara. As the leading web-hosted on-demand sales tax solution, AvaTax is offered as a Software-as-a-Service (SaaS) alternative to more expensive and less adaptive software sales tax calculating and management solutions.

"When we founded Avalara, we had a vision of revitalizing the manual and error-prone sales tax industry by delivering a transactional tax solution via the Internet," said Scott McFarlane, founder, president and chief executive officer, Avalara. "We've delivered on that vision through an affordable SaaS solution, and to have 1,000 businesses and more than 20,000 users utilizing AvaTax and its components are significant achievements. While our competitors scramble to switch from traditional enterprise software models, we continue to pioneer the SaaS sales tax movement for calculation, reporting, returns and remittance while exceeding our customers' expectations. As momentum continues to increase for sales tax automation, we expect to double our AvaTax customer base in 2008 and reach the 2,000 business mark."

Through the SaaS AvaTax solution, Avalara provides small- and mid-sized businesses (SMB) clients the outsourced power of a real-time transactional tax solution that employs the current tax rates, sourcing, jurisdictional assignment, taxability rules, and exemption requirements. The innovative SaaS approach offers SMB clients functionality that previously was only available to large enterprises.

"Sales tax automation is inevitable. Sales tax compliance is a statutory requirement that has no benefit to businesses, only risk. Sales tax compliance is perfect for automation and outsourcing, and software-as-a-service is the perfect model to deliver the service to small and medium business around the world," said McFarlane.

"Avalara has been proactive and visionary at building a business to provide tax processing using SaaS techniques," said Randy Johnston, executive vice president of K2 Enterprises, a premier provider of technology continuing professional education (CPE) in the United States and Canada. "They observed a need and have fulfilled it in a way no one else has done."

AvaTax offers the most accurate and affordable global solution for sales, use and VAT tax management services to SMB clients. Through the solution, Avalara processed more than 10.5 million transactions in January 2008 alone. "We filed $714 million in sales tax returns for January filings, with $411 million of that total processed in approximately 7,800 separate filings completed in just two days through our automated remittance service," said Rory Rawlings, founder and chief tax automation officer at Avalara. "That's quite an accomplishment for our business."

Avalara has continued strong and impressive growth since first offering its products in early 2005, when it had approximately 100 users and reseller-partners. Today the company serves more than 21,000 customers across all of its product lines including solutions that manage, automate and simplify sales tax and compliance tasks.
