Thank you very much.

So, two questions, 

You said,  "if you wish to upgrade, yes, you no longer have access to your older companies."

What is an "Upgrade" exactly, and if I do, what happens to my old companies?

I ask that because you mention -->

in case you'd feel the need to upgrade to a newer version of QuickBooks Desktop

I wouldn't mind paying and upgrading to the latest version of Desktop, but does this mean it has to be a subscription?

Thanks again, and have a good day

Bob
