Opening Balance Equity
QuickBooks Online (QBO) creates this account the first time you enter an opening balance for a Balance Sheet account. As you enter the opening balances, QBO records the amounts in the Opening Balance Equity account. This ensures that you have a correct Balance Sheet for your company, even before you have entered all your company's assets and liabilities.
After you have entered all of your opening balances, you might want to move the amount in Opening Balance Equity to your other equity accounts, but you will want to consult your accountant for advice.
