Journal Entries: How to Know Which Accounts to Use

Choosing the sides is the easy half. The hard half is turning a sentence into two account names, and knowing when the answer is Prepaid Insurance rather than Insurance Expense.

Quick answer: pick the accounts before the sides

Most people learn the debit and credit rules and still freeze when handed a sentence like "paid RM 6,000 for twelve months of insurance". The rules were never the problem. Naming the accounts is.

Work through four questions in order, and only reach for debit and credit at the very end.

QuestionWhat you are looking forNotes
1. What did the business receive?Cash, stock, equipment, or a service consumedThis is usually one account
2. What did it give up or now owe?Cash paid out, or a new obligation createdThis is usually the other account
3. Has the cash moved at a different time?Paid early, or used now and paying laterThis is where prepaid, accrued, and unearned accounts appear
4. What type is each account?Asset, liability, equity, revenue, expense, drawingsOnly now does the debit or credit side get decided

Once the accounts are named, deciding the side is mechanical. If that part is still shaky, the guide on which side to use and why banks say the opposite covers it.

Turning a sentence into an entry

Every transaction is an exchange. The business gets something and gives up something, and each half of that exchange is one account.

Take "the business paid RM 800 rent for this month by bank transfer". The business received the use of premises for the month, which is Rent Expense. It gave up money in the bank, which is Cash. Two accounts, identified before any thought about sides.

Question three is where most difficulty lives. If the cash moved at a different time from the benefit, the obvious account is the wrong one. That is the whole reason accounts like Prepaid Insurance and Unearned Revenue exist.

Key terms in plain English

Journal entry
The record of one transaction, listing the accounts affected and the amount debited and credited. It is where a transaction enters the books.
Narration
The short explanation written under an entry saying what it was for. It is what makes the entry understandable to someone reading it months later.
Compound entry
An entry with more than two lines. Perfectly valid, as long as total debits still equal total credits.
Prepaid expense
Something paid for before it is used. It is an asset until consumed, which is why it is Prepaid Insurance and not Insurance Expense on the day you pay.
Accrued expense
Something used before it is paid for. It is a liability, because the benefit has been taken and the obligation to pay exists.
Unearned revenue
Money received before the work is delivered. It is a liability, not revenue, because the business still owes the customer something.
Adjusting entry
An entry made at period end to move amounts into the period they belong to, such as converting part of a prepayment into an expense.

When the cash and the benefit happen at different times

This single table answers the question that trips up more beginners than any other: when to use Prepaid Insurance instead of Insurance Expense, or Unearned Revenue instead of Revenue.

SituationAccount to useTypeExample
You pay before you use itPrepaid ExpenseAssetInsurance paid 12 months ahead
You use it before you payAccrued ExpenseLiabilityMarch electricity billed in April
Customer pays before you deliverUnearned RevenueLiabilityDeposit for work starting next month
You deliver before the customer paysTrade ReceivablesAssetInvoice issued on 30-day terms

The pattern is consistent. Paying early creates an asset, because you are owed something. Receiving early creates a liability, because you owe something. Using before paying creates a liability, and delivering before being paid creates an asset.

These balances do not sit there forever. An adjusting entry moves them across as the benefit is consumed or the work is delivered, which is shown in the second worked example below.

Entries with more than two lines

Nothing says an entry must have exactly one debit and one credit. A compound entry can have several lines on either side, and it is correct as long as the two totals agree.

This is where entries most often go wrong, because a missing line is easy to overlook when there are four or five. Checking the totals with the journal entry checker catches that quickly.

Five sentences turned into entries

1. Paid RM 500 cash for office supplies used this month

AccountDebit (RM)Credit (RM)
Office Supplies Expense500-
Cash-500

Why these accounts. The business received supplies and consumed them now, so the benefit and the payment happen together. No timing account is needed.

2. Paid RM 6,000 for twelve months of insurance in advance

AccountDebit (RM)Credit (RM)
Prepaid Insurance6,000-
Cash-6,000

Why these accounts. Cash left now but no insurance cover has been used yet, so the business is owed something. That makes it an asset rather than an expense. Insurance Expense would be wrong on this date.

2a. One month later, the adjusting entry

AccountDebit (RM)Credit (RM)
Insurance Expense500-
Prepaid Insurance-500

Why these accounts. One twelfth of the cover has now been consumed, so RM 500 moves out of the asset and into the expense. Repeating this monthly empties the prepayment over the year.

3. Received RM 3,000 from a client for work starting next month

AccountDebit (RM)Credit (RM)
Cash3,000-
Unearned Revenue-3,000

Why these accounts. Cash arrived but nothing has been delivered, so the business owes the client work. That is a liability. Crediting Revenue here would report income the business has not earned.

4. Used RM 400 of electricity in March, bill arrives in April

AccountDebit (RM)Credit (RM)
Electricity Expense400-
Accrued Expenses-400

Why these accounts. The benefit was consumed in March, so the cost belongs to March even though no invoice exists yet. The unpaid obligation is a liability.

5. Sold RM 1,000 of goods, RM 400 paid in cash and RM 600 on credit

AccountDebit (RM)Credit (RM)
Cash400-
Trade Receivables600-
Revenue-1,000

Why these accounts. One sale produced two different assets, so the entry needs three lines. Total debits of RM 1,000 still equal the single RM 1,000 credit.

Four traps worth naming

1. Reaching for debit and credit too early

The sides are the last decision, not the first.

Example

Given a sentence about paying rent, people immediately think about which side rent goes on before confirming whether the account is Rent Expense or Prepaid Rent.

Why it matters. Choosing a side for the wrong account produces an entry that balances perfectly and is still wrong. The trial balance will never flag it.

What to do. Name both accounts in full before thinking about sides at all.

2. Expensing something paid for in advance

Paying does not make it an expense yet.

Example

RM 6,000 of insurance covering the next twelve months is debited entirely to Insurance Expense on the day of payment.

Why it matters. The benefit has not been consumed. Recording it all as an expense understates profit this period and overstates it in the eleven periods that follow.

What to do. Debit Prepaid Insurance, then move RM 500 into Insurance Expense each month with an adjusting entry.

3. Treating a deposit as revenue

Cash received is not the same as revenue earned.

Example

A RM 3,000 deposit for work starting next month is credited to Revenue on receipt.

Why it matters. The business still owes the customer the work, so the amount is an obligation rather than income. Recording it as revenue overstates this period and leaves nothing for the period the work is actually done.

What to do. Credit Unearned Revenue, and move it to Revenue as the work is delivered.

4. Forgetting to reverse an accrual

The expense gets counted twice when the real invoice arrives.

Example

March electricity is accrued at RM 400. In April the actual bill is posted in full, and nobody removes the accrual.

Why it matters. The same cost now sits in the books twice, overstating expenses and understating profit. It also leaves a liability that never clears.

What to do. Reverse the accrual at the start of the new period so the real invoice can be posted normally.

Notice that all four produce entries that balance. A wrong account never disturbs the totals, which is why they survive into the trial balance untouched. The guide on errors a balanced trial balance will not catch explains how they are eventually found.

Checklist for any entry

  • I wrote down what the business received before thinking about sides.
  • I wrote down what it gave up or now owes.
  • I checked whether the cash moved at a different time from the benefit.
  • I used a prepaid, accrued, or unearned account where the timing differed.
  • I identified the account type for every line.
  • I applied the debit and credit rule for each type.
  • I confirmed total debits equal total credits.
  • I added a narration explaining what the entry was for.

Journal Entry FAQs

How do I know which accounts a transaction affects?

Ask what the business received and what it gave up or now owes. Those two answers are usually your two accounts. Then check whether the cash moved at a different time from the benefit, because that is when a prepaid, accrued, or unearned account belongs in the entry instead of the obvious one.

What is the difference between the journal and the ledger?

The journal records transactions in date order as they happen, so it reads like a diary. The ledger groups the same entries by account, so you can see everything that hit Cash or Rent Expense in one place. Every entry starts in the journal and is then posted to the ledger.

Do debits always have to be listed before credits?

By convention yes. Debit lines are written first and credit lines below them, usually indented. It is a formatting convention rather than a rule that changes the accounting, but following it makes entries far quicker for someone else to read.

Is a narration required on a journal entry?

It is not mathematically required, but leaving it out is a mistake you will regret. Months later, an entry without an explanation is very hard to verify or correct, and it is usually the first thing an auditor or accountant asks about.

What is an adjusting entry?

An entry made at period end to move amounts into the period they belong to. Converting one month of a twelve-month prepayment into an expense is an adjusting entry, as is recording an expense that has been incurred but not yet billed.

Does the Journal Entry Checker tell me if I picked the right accounts?

No. It totals your debit and credit lines and confirms whether the entry balances, which catches arithmetic problems and missing lines. Whether Prepaid Insurance was the right account rather than Insurance Expense is a judgement it cannot make, and a wrong account will still balance perfectly.
