Thanks for dropping by, @mcoult45.

Currently, we don't have an updated workbook that you can rely on to practice more complex scenarios in QBO. However, you can look for blog sites and other websites to look for an updated workbook. Also, I suggest visiting this page: QuickBooks Online Courses. There you can experience the best of our professional QuickBooks Online trainers.

Training resources are available before you take the advanced certification. In addition, you can test yourself with these unanswered posts: Unanswered questions. Professional Tax Advisors, Accountants, All-Stars (experienced QuickBooks professionals and accountants), QuickBooks Community, and experienced QuickBooks Online users gather to this site to help other users.

There you can practice yourself with your answers. Make sure to look for the product tagging before answering the question.

Just in case you want to try or test something in QBO, you can use our test drive: https://qbo.intuit.com/redir/testdrive.

Please let me know if you have more questions. I'll wait for your reply here. Stay safe and healthy!
