Can you be more specific? What do they need to do? Do they download the latest premier trial? Enterprise? They do not trust this will allow them to view their data indefinitely. Can I get verification from Intuit?

Again, they do not want to edit the old data; just view, and possibly print relevant items. You only allow 2 years of history to be imported and they've been around and using QB for 20+ years. They have customers who owed them in the past and want to pay up and start buying again. I don't want to get into how they would post that in QBO, they just need to see the details in the desktop file.
