"We continue to believe that the automation of transaction tax compliance will be adopted over an extended period, as customers upgrade systems, expand their businesses both domestically and internationally, and respond to changing government rules...We believe our broad tax content, robust platform, partner channel, and pre-built integrations position Avalara as a clear choice to lead this automation cycle," said Avalara CEO Scott McFarlane in prepared remarks included in the earnings release.
