Hi there d2jump,
It's vital for all business owners to keep their books in order in the most effective way possible to save time. QuickBooks Desktop is a robust program able to help you keep track of assets, liabilities, sales and expenses so you can see how well your company is doing financially. I can point you in the right direction for assistance with the best ways of navigating in the software.
In order to know the most effective ways of changing between companies in your QuickBooks Desktop program, I recommend reaching out to the QuickBooks Desktop support team. They'll be able to verify the ways you're currently using in order to suggest quicker ways to pivot between companies if there are more effective methods available. You can reach out to them using the methods provided in the QuickBooks Desktop software support policies.
