A journal entry is a record of an accounting transaction.  It can be a transfer from one account to another or a full summary of a day's transactions like what we do at bookkeep.com.  

Below is an example from QuickBooks.  You must choose an account for each line and EITHER a debit or credit amount.

Very important to note that the debits totals MUST match the credits totals or you cannot record the entry.  (Read more about a Perfectly Balanced Daily Summary).
