I love that you're checking out the new Month-End Review feature available to QuickBooks Online Accountant users! It's already a hit with many accountant users, so I want to make sure you have the information you need to give it a go as well. I'll show you where you can find more information about it.
There isn't a QuickBooks Community article about this feature just yet, but that's coming shortly. In the meantime, I invite you to check out this Firm of the Future blog that goes over this feature and how to use it: QuickBooks can do WHAT? Month-end review. With its screenshots and helpful explanations, it should help you with creating the items you need with this feature.
