Super-simple API integration to add tax handling to a web application
TaxJar was very easy for us to implement, didn't require hoops and red tape to get setup, and has been foolproof for us so far. The error messages...have been clean and easy to correct. It's a great comfort knowing we don't have to worry about the tax implications of transactions -- we just submit the data to TaxJar and they tell us how much to charge. Awesome!
