Smart Contractor can be run "stand alone" on one computer, or networked with any number of users

You can also run Smart Contractor on a laptop in "offline mode" where you take a copy of your office database with you in the field, make any updates or changes, and then merge it back into the office database - even after the office staff has been making changes in it.

You can run Smart Contractor with or without QuickBooks.
