The General Journal is an advanced register used to enter transactions without needing to open individual accounts. The General Journal shows the transaction entries for all accounts on one register.
Entering transactions in the General Journal is more complicated than entering them in the individual account registers. The advantage is the General Journal provides a more comprehensive view of the transactions you have entered in all your accounts.
The General Journal defaults to showing only the previous month of transactions. This is changeable by using the "Filter By..." on the View menu.
