How to void, reverse, or delete a journal entry form a year ago?

Hi there haroldc1,

It's important that all your transactions are entered correctly so that your books are well-balanced. QuickBooks Online is a great tool able to help you keep track of sales and expenses so you can see the profit of your business. I can provide some information about reversing a journal entry.

Deleting a journal entry will affect last year's books, so if you'd like to affect the current period instead, you can create a new journal entry in the current period affecting the same accounts, except that the credits and debits from the original entry are reversed.
