We have an ecommerce solution that calculate the accurate tax with a web service based on State, City and County. However we cannot insert into the TAX field through the DI API. I was considering different options like inserting the tax amount in a additional expense or sinchronizing the TAX code per state into the ecommerce so once a State is selected in the shipping address we know which tax percentage needs to be charge into the order? has anyone experienced something similiar?
Thanks in advance
