It's great that you're looking to optimize your use of QuickBooks Desktop, NMiller640.
I'll go into detail about which version of QuickBooks Desktop enables you to have two company files open simultaneously.
Only QuickBooks Accountant and QuickBooks Desktop Enterprise allow you to do this. In these versions, the first opened file is labeled Primary, and the second is labeled Secondary.
However, it's important to note that not all QuickBooks versions have this capability. Both QuickBooks Pro and Premier versions lack the functionality to open multiple company files simultaneously. So, if you're working with one of those versions, you'll need to manage one company file at a time.
Feel free to explore this article for further insights: Open and use a secondary company file in QuickBooks Desktop. It should provide you with more detailed information on the process.
Additionally, I'll provide you with an article that can be a helpful resource if you're interested in learning how to issue bills or checks between your different company files in QuickBooks. Here’s the link: Create transactions between different company files in QuickBooks Desktop Enterprise.
