A journal entry in QuickBooks Online is a way to manually record financial transactions that don't fit into other transaction types. It is useful for adjusting entries, correcting errors, recording opening balances, and handling specialized transactions.
To create a journal entry in QuickBooks Online, you can access the journal entry feature and enter the necessary details such as accounts, amounts, and descriptions. QuickBooks Online will automatically update the general ledger and financial statements based on the information provided in the journal entry.
