Welcome to the Community, @Haris4535.

Let me share some insights about why the balance sheet amounts for Accrued Payroll are not consistent monthly in QuickBooks Online (QBO).

One potential reason is the shortfall in the 3rd and 4th months' Accrued Payroll Expenses could be an incorrect account posting, or it may not have been recorded.

In QBO, it is important to ensure that the balance sheet date range matches when you created the Journal Entry for payroll. If confirmed, you can verify the transactions in the Accrued Payroll expense account to check if the correct amount is posted.

I'll also add these articles to guide you through the process of managing your payroll in QBO: 

• Create and run your payroll
• Set up and manage payroll schedules

I’ll be around the corner if you need an extra pair of hands in any QuickBooks-related matters. Stay safe, @Haris4535.
