Which version of QuickBooks will allow the user to toggle between versions?

QuickBooks Desktop allows users to toggle between different versions, specifically between QuickBooks Desktop Pro, Premier, and Enterprise, through the use of the QuickBooks Desktop multi-user mode. However, users must ensure that all versions are compatible and properly installed on their system. QuickBooks Online, on the other hand, does not provide the option to toggle between versions, as it is a single, cloud-based version with different subscription tiers.
