Posting Transactions in Journal Entries

Transactions passed what is referred to as the Accounting cycle. The first step in this cycle is the subsidiary books. In practice, however, most of the types of this book are not used. Journal books and cash books are the only common prime books used by most entities. I have discussed the cash book here. In this article, a practical guide on journal entry is discussed.

Step 1: Understand the transaction. Without a transaction there cannot be a journal entry. Therefore, you need to understand the transaction. If you do not understand it, ask a question from your superior or the person initiating the transaction. It is when you have an understanding of the transaction you can move to the next step.

Step 2: Identify the accounts in the transaction. You can learn more about how to understand a transaction here. Generally, a transaction usually has two accounts. However, some transactions may involve more than two accounts. If you have understood the first step, there will be little difficulty in identifying the accounts involved.

Step 3: Identify the account(s) to debit and that to credit. This can be done by applying the double-entry principle. That is, debit the receiver of value and credit the giver of value.

Step 4: Draw up the Journal book. Now you can write up the journal entries and post the debit and credit account and amount accordingly. The debit and credit side must have the same amount.

Step 5: Give a narration. The last step is to provide narration or summary of the transaction. Your narration should be simple and easy to understand by someone who wasn’t there when the transaction was initiated and recorded. The narration may also include the date the transaction occurs if such date is different from the date the Journal book is prepared.


Below are two examples of recording transactions in a journal book.

Example One: Payment of electricity bill through a bank debit of 5,000 Naira on 15th September 2020.

Here the accounts involved are Electricity bill and bank account. While the amount is N5,000 Naira and the date is the 15th of September.

Remember that double-entry principle requires debit of the receiver of value and credit of the giver of value.

From the above, Electricity bill is receiving the value while the bank is giving or paying the bill. Therefore, Debit the Electricity bill account and Credit Bank account. This is shown in the journal entry as seen below.

Posting transactions in the journal entry

Example Two: A customer, Mr Dennis was mistakenly credited by an amount of 100,000 Naira for repayment of debt instead of Mr Daniel’s.

The person who initiated the transaction was Mr Daniel. But, Mr Dennis’ account was credited. This is an error and correction or reversal of the entry must be done using a journal book.

Therefore, Mr Dennis’ account will be debited to remove the money from his account. Then, Mr Daniel’s account will be recorded correctly by crediting his account with the amount. This is shown in the MS Excel sheet below. You may also notice the narration.
