Iwould like to follow along in QBOPlus online

Hi, Rosadmit. In QuickBooks Online (QBO), there's a test drive sample company file available that you can use to practice and get comfortable with the product. 

The QBO Test Drive is a free demo that allows users to learn, practice, and troubleshoot without affecting actual financial data. Users can create invoices, generate reports, and test workflows, with all changes resetting after closing the session. For more details, please refer to this article: Test drive and practice using QuickBooks Online.

However, please note that the Test Drive sample file does not reflect all the latest updates in the software. To access and explore all features and options, consider using the 30-day free trial of QBO as an alternative. You can find more information about the free trial in this article: QuickBooks Online Pricing &  Free Trial | Official Site.

Please let us know if you require any additional assistance with this matter. We'll be around to help.
