Some transactions in Netsuite need to have the tax based on the origin address only.
- Use the AvaTax-POS tax code on the transactions.
Note: It may be necessary to create this tax code if it doesn't already exist. In that case, simply duplicate the settings for your AvaTax tax code, but make the tax code name "AvaTax-POS" instead of "AvaTax".
