Hi LJS72,
Welcome to the Community. QuickBooks Online is a great program that gives you the ability to easily manage your books. I'd be glad to provide you with information regarding the budget feature.
At this time, the program doesn't offer the option to create budgets for the balance sheet. You can create budgets for profits and losses.
If you'd like to include the option to create budgets for the balance sheet, I recommend that you send us Feedback by clicking on the Gear icon at the top. This is sent to our Development Team to consider for future updates.
Let me know if you have questions, I'll be happy to help.
