Thanks for joining the thread, @drako42.

Allow me to provide some info about customizing the balance sheet in your QuickBooks Online Accountant account.

You can customize the balance sheet in your account using the steps provided by my colleague @JamesDuanT above. These reports are the same in QuickBooks Online and the QuickBooks Online Accountant Edition. 

If you don't see these customization options, I recommend opening the program in a private browser where your web information data isn't saved. Then, you can customize the balance sheet to show non-zero balances. After doing so, you'll want to clear your cache and cookies to help prevent any loading or formatting issues within QuickBooks again.

I'm only a post away if you have any other questions. Best wishes!
