Hi there, @ Lisa J.
Pulling up a balance sheet report on a class that includes the opening balance is not yet an option in QuickBooks Online. You can only pull up the running balance of a Class.
One of the reports that show the balance is the Transaction Detail By Account and filter it by Class.
To do that:
- On the left panel, click Reports.
- Type Transaction Detail by Account in the search box.
- Change the Report period and click the Customize button.
- Click Filter to expand, put a checkmark for the Class box.
- Click on Run Report.
Here's an article for more information about customizing a report for future references: How to customize your Profit and Loss report.
Please let me know how that works. I'll be here and ready to help anytime. I'm cheering you on continued prosperity.
