I'm here to lend a hand with your question about reports in QuickBooks Online (QBO).
A Balance Sheet and Profit & Loss report contains similar information but also has some important differences which both provides a crucial analysis.

Since your Balance Sheet report is a cumulative report that carries a beginning balance.
