Under the Admin menu, go to Journal Entry.
Click New.

Choose relevant Period – it will default to the current period.
Enter the relevant Date.
In the Ref No field enter the journal number (if you want to number the journals) or include a note as to the nature of the journal (e.g. GST refund June).

Click Add Trans and Find the correct Account in the list.
Enter the Amount in either the Debit or Credit field.
Select the correct DR/CR. DR = debit and CR = credit.
Select the correct Tax Category and, if necessary, ensure the Tax Amount is correct.
Enter journal Details.

Continue clicking New Row until the journal is complete and the balance in the top right hand corner is $0.00.

Click Hold. This will save your journal, but not submit it to the system. You can now check the journal or leave the screen and come back and edit the journal later if necessary.
Once confirmed that the journal is correct, click Save.
