How do I get sales tax rates to pull from ShipCompliant?
First enable ShipCompliant in Nexternal (Settings/Compatible Software/Alcoholic Beverage Tools/ShipCompliant). Then navigate to Settings/Sales Tax/Third Party Sales Tax Provider, and pull down to ShipCompliant.
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.
