Turns out that sales taxes are more difficult to calculate than it might seem. More than 15,000 taxable regions inside the US form a mosaic for sales tax calculation. Fire districts, state districts, special taxation districts, and state rules on items all play a part. Avalara put together a new product to show the lines between taxation districts on Windows Azure.
ISV Architect Evangelist Bruce Kyle talks with Jared Vogt, Avalara's CTO, about how they developed the services, how they needed to think about moving an application from their data centers into Windows Azure. When they wanted to show on a map how a tax is calculated, they turned to Windows Azure and Bing Maps. Jared provides a demo too of GeoSalesTax.com.
