I have selected ShipCompliant within Nexternal to calculate sales tax rates, but the rates are not calculating as I expect - what could be the problem?
Response:
To get the rates you expect for each location, you will need to make sure that you have made the correct tax preference selections within ShipCompliant - please contact ShipCompliant with any questions on that.
Further, if a state requires that you charge tax on shipping as well as products, you will need to check the appropriate "TS" boxes within the Nexternal tax tables.
