Thanks for your interest with this feature in QuickBooks, @NNeese,

If you already purchased a QuickBooks Enterprise license and installed it on your computer, you have the option to use a test file. All live versions of the program is equipped with sample files so our customers can run tests without penetrating the actual account.

You can access the test account on the QuickBooks startup page when you launch the program. See this illustration:

If you're currently working on the actual company, you can switch to the sample file by clicking the File menu and selecting Close Company/Logoff.

Adding your business information is optional for test accounts. Access the company file anytime just like how you normally open the actual company.
