Yes, I had similar problem, the preview or print copy of invoice is missing Ship To:
Ask to refer: http://help.nchsoftware.com/help/en/expressaccounts/win/invoicelayout.html
Follow everything as advised, still the Ship To: is missing on preview and invoice copy.
I had checked that the Customer area the box checked, use mailing address as shipping address
Can it be a bug that need to be fixed?
