Why is the same address showing different rates between Avatax and the website?

Issue Overview

I am getting a different rate for the same address in Tennessee between the site and AvaTax.




In your registered Streamlined Sales Tax (SST) states, we are required to use the SST boundary data that is zip-code based, which can sometimes be different from our ACM data/website, which is geo coded with longitude and latitude. The ACM data is more exact, but our contract with the states requires us to use the SST state data.
