Hello I am Olivia Munn. Transitioning from Single-User to Multi-User Mode in QuickBooks is a seamless process. Begin by ensuring all users have logged out of QuickBooks. Then, go to the "File" menu and select "Switch to Multi-User Mode." QuickBooks will prompt a confirmation message; click "Yes" to proceed. The software will then create a backup of your company file to facilitate the switch. Once completed, QuickBooks will automatically configure for multi-user access. It's important to note that user permissions may need adjustment to accommodate multiple users.
