Accounting Logic System™ — Lesson 4
How to Identify a Business Transaction for Journal Entries
Before writing any journal entry, first understand what has actually changed in the business. This five-step method helps beginners identify the correct accounts, classify them and decide the debit and credit logically.

The Five-Step Transaction Identification Method
- Understand the transaction. Read the complete transaction and identify what the business received, gave, spent, earned, bought, sold, owes or is entitled to receive.
- Identify the affected accounts. Every transaction affects at least two accounts. Name each separate account; do not describe the effect as “one account twice.”
- Classify each account. Decide whether every affected account is Personal, Real or Nominal. For a three-account transaction, review the worked account-classification example.
- Apply the correct rule. Use the rule for that account type to decide which account is debited and which is credited.
- Determine the amount and write the entry. Debit and credit must be recorded for equal amounts. Add a short narration explaining the transaction.
Quick formula: Understand Transaction → Identify Accounts → Classify Accounts → Apply Rules → Determine Amount and Write Journal Entry.
Rules to Apply After Classification
| Account type | Debit when | Credit when |
|---|---|---|
| Personal Account | Receiver, or receivable from them | Giver, or payable to them |
| Real Account | Property comes in, or its value increases | Property goes out, or its value decreases |
| Nominal Account | Expense or loss | Income or gain |
For the meaning of the two sides of an account, first review Debit and Credit Explained Through Logic. For the complete framework, read the Modified Golden Rules of Accounting.
Worked Examples
Example 1: Started business with cash ₹1,00,000
- Accounts affected: Cash Account and Capital Account.
- Classification: Cash is a Real Account; Capital represents the proprietor and is a Personal Account.
- Logic: Cash comes into the business, so Cash Account is debited. The proprietor gives capital to the business, so Capital Account is credited.
- Journal entry: Cash A/c Dr. ₹1,00,000; To Capital A/c ₹1,00,000.
Example 2: Bought furniture for cash ₹20,000
- Accounts affected: Furniture Account and Cash Account.
- Classification: Both are Real Accounts.
- Logic: Furniture comes in, so Furniture Account is debited. Cash goes out, so Cash Account is credited.
- Journal entry: Furniture A/c Dr. ₹20,000; To Cash A/c ₹20,000.
Example 3: Sold goods on credit to Riya for ₹15,000
- Accounts affected: Riya Account and Sales Account.
- Classification: Riya is a Personal Account. Sales is a goods-related Real Account in the Accounting Logic System™.
- Logic: The amount is receivable from Riya, so Riya Account is debited. Goods go out through sale, so Sales Account is credited.
- Journal entry: Riya A/c Dr. ₹15,000; To Sales A/c ₹15,000.
Example 4: Paid shop rent ₹5,000 in cash
- Accounts affected: Rent Account and Cash Account.
- Classification: Rent is a Nominal Account; Cash is a Real Account.
- Logic: Rent is an expense, so Rent Account is debited. Cash goes out, so Cash Account is credited.
- Journal entry: Rent A/c Dr. ₹5,000; To Cash A/c ₹5,000.
Example 5: Received commission ₹3,000 in cash
- Accounts affected: Cash Account and Commission Account.
- Classification: Cash is a Real Account; Commission is a Nominal Account.
- Logic: Cash comes in, so Cash Account is debited. Commission is income, so Commission Account is credited.
- Journal entry: Cash A/c Dr. ₹3,000; To Commission A/c ₹3,000.
Special Note About Goods Accounts
In this learning system, accounts connected with goods are treated as Real Accounts because they represent the movement or value of goods. These include Purchases, Sales, Purchase Return, Sales Return, Opening Stock, Closing Stock and Goods Destroyed. Always identify whether goods come in, go out, increase or decrease before deciding the effect.
Transaction Analysis Worksheet
Before writing the Journal entry, complete one row for every affected account. A simple worksheet prevents beginners from skipping an account or applying one rule to every account.
| Account affected | Type | What changed? | Rule applied | Effect | ₹ |
|---|---|---|---|---|---|
| Account 1 | Personal / Real / Nominal | Receiver, giver, property, expense, income, receivable or payable | Write the exact applicable rule | Debit / Credit | Amount |
| Account 2 | Personal / Real / Nominal | Describe the second effect | Write the exact applicable rule | Debit / Credit | Amount |
| Additional account, if any | Personal / Real / Nominal | Describe its separate effect | Apply its own rule | Debit / Credit | Amount |
Control check: add all debit amounts and all credit amounts. The totals must be equal even when three or more accounts are involved.

Illustration 6: Purchased goods for cash ₹12,000
| Account | Type and logic | Effect | ₹ |
|---|---|---|---|
| Purchases A/c | Goods-related Real Account; goods come in | Debit | 12,000 |
| Cash A/c | Real Account; cash goes out | Credit | 12,000 |
Solution: Purchases A/c Dr. ₹12,000
To Cash A/c ₹12,000.
Illustration 7: Returned goods worth ₹3,000 to Ayaan
| Account | Type and logic | Effect | ₹ |

Solution: Ayaan A/c Dr. ₹3,000
To Purchase Return A/c ₹3,000.
Illustration 8: Received ₹14,500 from Riya in full settlement of ₹15,000
Three accounts are affected. Cash comes in; Discount Allowed is a loss; Riya gives value and her ₹15,000 receivable balance is settled.
| Account | Type and logic | Effect | ₹ |
|---|---|---|---|
| Cash A/c | Real Account; cash comes in | Debit | 14,500 |
| Discount Allowed A/c | Nominal Account; business loss | Debit | 500 |
| Riya A/c | Personal Account; giver and receivable settled | Credit | 15,000 |
| Total | Debit = Credit | 15,000 |
Solution: Cash A/c Dr. ₹14,500
Discount Allowed A/c Dr. ₹500
To Riya A/c ₹15,000.
Illustration 9: Paid Ayaan ₹24,000 in full settlement of ₹25,000
Ayaan receives the settlement; Cash goes out; Discount Received is a gain.
| Account | Type and logic | Effect | ₹ |
|---|---|---|---|
| Ayaan A/c | Personal Account; receiver and payable settled | Debit | 25,000 |
| Cash A/c | Real Account; cash goes out | Credit | 24,000 |
| Discount Received A/c | Nominal Account; business gain | Credit | 1,000 |
| Total | Debit = Credit | 25,000 |
Solution: Ayaan A/c Dr. ₹25,000
To Cash A/c ₹24,000
To Discount Received A/c ₹1,000.
Illustration 10: Bought goods for ₹30,000; paid ₹10,000 cash and the balance is payable to Meera
Do not force this transaction into only two accounts. Goods worth ₹30,000 come in, Cash ₹10,000 goes out, and ₹20,000 becomes payable to Meera.
| Account | Type and logic | Effect | ₹ |
|---|---|---|---|
| Purchases A/c | Goods-related Real Account; goods come in | Debit | 30,000 |
| Cash A/c | Real Account; cash goes out | Credit | 10,000 |
| Meera A/c | Personal Account; amount payable to her | Credit | 20,000 |
| Total | Debit = Credit | 30,000 |
Solution: Purchases A/c Dr. ₹30,000
To Cash A/c ₹10,000
To Meera A/c ₹20,000.
How to Read Compound Transactions
- Write every separate benefit, sacrifice, expense, income, receivable and payable.
- Create one account for each separate effect.
- Classify and apply the rule to each account independently.
- Do not assume that every transaction affects exactly two accounts; it affects at least two accounts.
- Use the debit-total-equals-credit-total check before writing the narration.
Common Mistakes to Avoid
- Writing a journal entry before naming all affected accounts.
- Confusing the person with the cash, property, expense or income involved.
- Calling debit “bad” and credit “good.” Debit and credit are simply the left and right sides of an account.
- Using “receiver and giver” for every account type. That logic belongs only to Personal Accounts.
- Forgetting that total debit and total credit must always be equal.
Practice Questions
Apply the five steps to these transactions before checking your answer:
- Purchased machinery for cash ₹40,000.
- Paid salary ₹8,000.
- Bought goods on credit from Ayaan ₹25,000.
- Received interest ₹2,000.
- Paid ₹10,000 to a supplier whose amount was payable.
For each transaction, write: affected accounts → account type → applicable rule → debit account → credit account → amount.
Practice Answer Key
| Question | Debit | Credit | Reason |
|---|---|---|---|
| 1. Machinery purchased for cash ₹40,000 | Machinery A/c ₹40,000 | Cash A/c ₹40,000 | Machinery comes in; Cash goes out. |
| 2. Salary paid ₹8,000 | Salary A/c ₹8,000 | Cash A/c ₹8,000 | Salary is an expense; Cash goes out. |
| 3. Goods bought on credit from Ayaan ₹25,000 | Purchases A/c ₹25,000 | Ayaan A/c ₹25,000 | Goods come in; amount becomes payable to Ayaan. |
| 4. Interest received ₹2,000 | Cash A/c ₹2,000 | Interest A/c ₹2,000 | Cash comes in; Interest is income. |
| 5. Paid supplier ₹10,000 against the amount payable | Supplier’s A/c ₹10,000 | Cash A/c ₹10,000 | The supplier receives payment; Cash goes out. |
Answer control: each entry has equal debit and credit. If your result differs, return to the affected accounts and apply each account’s own rule.
Worked Timeline: Order, Supplier Advance and Delivery
Scenario: A business places an order for goods worth ₹50,000. Before delivery it pays the supplier ₹20,000 by bank. The supplier later delivers all the goods on credit and adjusts the advance. This timeline shows when a recordable transaction arises.
| Stage | What changed? | Entry |
|---|---|---|
| 1. Order placed | No goods received, no payment made and no present payable recorded in this basic example. | No Journal entry |
| 2. Advance paid | Bank decreases ₹20,000; a recoverable Supplier Advance asset arises. | Supplier Advance A/c Dr. ₹20,000 To Bank A/c ₹20,000 |
| 3. Goods delivered | Goods worth ₹50,000 come in; ₹50,000 becomes payable to the supplier before adjustment. | Purchases A/c Dr. ₹50,000 To Supplier A/c ₹50,000 |
| 4. Advance adjusted | The ₹20,000 advance asset is used against the supplier balance. | Supplier A/c Dr. ₹20,000 To Supplier Advance A/c ₹20,000 |
Closing payable: Supplier credit ₹50,000 − advance adjusted ₹20,000 = ₹30,000 credit balance. The advance account closes to zero.
Independent control checks
- Advance entry: Debit ₹20,000 = Credit ₹20,000.
- Delivery entry: Debit ₹50,000 = Credit ₹50,000.
- Adjustment entry: Debit ₹20,000 = Credit ₹20,000.
- All recorded stages combined: Debit ₹90,000 = Credit ₹90,000.
- No second Bank entry is made when the advance is adjusted; the bank payment was already recorded at Stage 2.
Why the order alone is different: placing an order is a business event, but this basic example does not yet change a recognised account balance. Contract terms, taxes and reporting requirements may require separate treatment in real cases; they are outside this introductory illustration.
After identifying the recordable stages, see Journal Entries Step by Step and then post each opposite account through Ledger Posting Step by Step.
Frequently Asked Questions
How many accounts can one business transaction affect?
A transaction affects at least two accounts, but a compound transaction may affect three or more. Identify every account before deciding the debit and credit sides.
How do I distinguish a cash transaction from a credit transaction?
If money is paid or received immediately, Cash or Bank Account is affected. If payment is postponed, the supplier or customer’s personal account is affected instead.
Should every purchase be recorded in Purchases Account?
No. Purchases Account is used for goods bought for resale. Furniture, machinery and other long-term assets must be recorded in their respective asset accounts.
What final check should I make before writing the Journal entry?
Add all debit amounts and all credit amounts. The totals must be equal, and each amount must relate to an account actually affected by the transaction.
