I'm getting an error when we try to sync method to QuickBooks. It appears that there is a problem with the sales tax on invoices but we don't see anything wrong with the invoices in QuickBooks. Here is the text from the error, any ideas?
QuickBooks returned an error when adding/modifying a accInvoice record. The
error was: There was an error when modifying a Invoice. QuickBooks error
message: The Transaction Sales Tax field cannot be left blank, even for
non-taxable customers and sales which have no taxable items, so non-taxable
sales will be correct for this district.. The Request was: <?xml
