Avalara

Avalara solves Tax. But it's not like you may think. Imagine every product you buy, every service you subscribe to, every transaction you make. It all needs to be taxed. Every city, county, state, country taxes differently and every transaction which crosses those boundaries (effectively every transaction) needs to account for those differences. Now imagine retailer (brick/online), the wholesaler, manufacturer, importer/exporter and the depth and breadth of the challenge in getting the tax right. Avalara takes on that burden and makes it easier for businesses of all sizes to do business globally. It's a very challenging domain in terms of scale, reliability and complexity and Avalara do it better than anyone.
