QB Issue Resolution:

“but I think I heard that an external drive would not work for hosting for QB 2015 and later.”

You can keep the Data file there.

The Program cannot be installed or “hosted” there. It is Installed on the C: drive of each computer, so that it updates the Registry. This is Windows, anything newer than XP.

“I would prefer the external ssd if it would work. I have 3 users at work (including me), and only me using at home.”

For Multi-User (concurrent) at the office, one of the computers has to be Hosting the database; not the program.

“I am currently using QB 2013 Premier, but have already purchased QB 2016 and want to check prior to installing. If we can use the external drive, we would just backup to the work and home computers prior to moving between (daily backups). Any help appreciated”

You would not Backup and move, if you are Moving the external drive.

I suggest you might want to check into Desktop Hosted, such as MyCloud or Qbox, or other solutions.
