Switching from your actual account to a demo version isn't possible. Nonetheless, you'll be glad to know there's a workaround you can use, Alex.
You can subscribe to a trial version of QuickBooks Online. This option will allow you to practice and explore all the features without impacting your original company data.
Once subscribed, please know you have 30 days to use the trial version. To access it, log out of your original account and log in to the trial account using your new credentials.
Now that you're just getting started with the software, you might want to adjust your QuickBooks homepage. This feature allows you to configure the layout of your dashboard so it displays the information most relevant to your business needs and personal preferences.
Ensuring you have a smooth and successful experience with our software is a top priority, Alex. I'm glad we found a workaround to let you practice safely with a trial account. Remember, you have 30 days to explore and familiarize yourself with the available features.
