Specifying Multi-User Mode
For more than one person to work with a QuickBooks file at once, users must work with the QuickBooks file in multi-user mode. The first person who opens the file needs to specify multi-user mode for others to be able to open the file. To specify multi-user mode, choose File⇒Switch to Multi-User Mode. You can tell that you’re working in multi-user mode because the QuickBooks title bar indicates so. When other people open the QuickBooks file, it automatically opens in multi-user mode. For another user to work in single-user mode, the other users must close the QuickBooks file, and the user wanting to work in single-user mode needs (or may need) to choose File⇒Switch to Single-User Mode command.
