SaaS-based sales tax automation service provider Avalara has added certifications for Microsoft Dynamics AX and NAV to its AvaTax Web-based sales tax tool.

The certification signifies that AvaTax has met Microsoft’s highest standard for partner-developed software and can now carry the Certified for Microsoft Dynamics (CfMD) logo for Microsoft Dynamics AX, GP and NAV products. Avalara earned certified status for Microsoft Dynamics GP in 2010.

According to Microsoft, solutions that are CfMD have demonstrated development quality and compatibility with the Microsoft Dynamics product on which they run by passing rigorous software testing for Microsoft Dynamics performed by VeriTest, a service of Lionbridge. 

In addition, the Microsoft Dynamics partner must be either a Silver or Gold Certified Partner in the Microsoft Partner Program and must have customers who are successfully using the certified solution and are willing to recommend it.

“Our promise to provide a fast, accurate and affordable way to simplify the complexity associated with sales tax extends across all ERP solutions we support,” said Avalara founder and chief executive Scott McFarlane. “Achieving the CfMD designation three times over further illustrates our commitment to software excellence.”

Avalara specializes in seven Microsoft Dynamics products: AX, AX for Retail, CRM, GP, NAV, RMS and SL.
