The Seattle, Wash.-based sales tax software company lost $24.1 million in the most recently ended quarter, compared to $10.3 million in red ink a year earlier. Revenue for the quarter was almost $70 million, up from $55.3 million last year. In the company’s first earnings webcast, CEO Scott McFarlane said the Supreme Court’s Wayfair decision and major regulatory change in other countries are driving interest in Avalara products.  “We are seeing increasing business activity,” he said. He noted 29 states have adopted economic nexus laws that require remote sellers to collect sales tax, following the Wayfair decision. These factors “are driving interest and customer conversations.” McFarlane said the mid-market remains the biggest sector for his company. But Avalara is also gaining notice from larger organizations. “Increasingly, enterprise companies are coming to us,” he said. Countries other than the United States represent an important area for growth.
