In Ostendo there are tax matrix's that are linked to an items product tax group and a customers company tax group.
When importing an order the system will look up the tax matrix and see if there is a tax code for the given product tax group and company tax group. If there is then it will use this tax code rather than the default tax code.
Please check with the client that if the are using tax matrix's and are they set up.
If the wrong Tax group is setup you may get an error message
