Tax rates are incredibly difficult to track at scale. There are more than 13,000 sales and use tax jurisdictions in the United States alone, and each one is subject to ongoing rate and taxability updates. A solution like Avalara allows you to offload the process of researching and applying the tax rates and rules valid at the point of sale. Automation both improves your tax compliance and reduces the amount of time and effort you or your staff have to put into determining product taxability and rates.
