Why this chapter matters
The practical heart of the subject. Journalising and the accounting equation carry heavy marks every year, and the debit/credit rules underpin every later chapter (ledger, trial balance, final accounts).

Recording of Transactions – I — Class 11 (Accountancy)

Now we start doing accounting. Every rupee that moves through a business must be captured — first as a journal entry, using the timeless rule of double entry: every transaction affects (at least) two accounts, one debited and one credited, and the totals always balance. Master this rule and the rest of accountancy follows.


1. The accounting equation

Every business always satisfies:

Because of the dual aspect, any transaction keeps this equation balanced. Expanded:

Example: Owner starts business with ₹1,00,000 cash → Assets (Cash) ₹1,00,000 = Capital ₹1,00,000. Buys goods for ₹20,000 cash → Cash −20,000, Stock +20,000 (assets side rearranged; equation still balances).


2. The rules of debit and credit

Every account is one of five types. The modern rules:

Account typeDebit (Dr) when…Credit (Cr) when…
Assetsincreasedecrease
Expenses/Lossesincreasedecrease
Liabilitiesdecreaseincrease
Capitaldecreaseincrease
Revenue/Income/Gainsdecreaseincrease

Memory aid: Debit what comes in / expenses & assets ↑; Credit what goes out / incomes, liabilities & capital ↑. For every entry, total debits = total credits.


3. Source documents and vouchers

Recording must be based on evidence:

  • Source documents — proof of a transaction: cash memo, invoice/bill, receipt, pay-in-slip, cheque, debit/credit note.
  • Vouchers — prepared from source documents to authorise recording:
    • Cash voucher (debit voucher for payments, credit voucher for receipts).
    • Non-cash/transfer voucher — for credit transactions.

The objectivity concept requires every entry to rest on a source document.


4. The Journal — book of original entry

The Journal is where transactions are first recorded, in date order, as journal entries. Format columns: Date | Particulars | L.F. | Debit (₹) | Credit (₹).

A journal entry names the account debited first, then the account credited (written below, prefixed "To"), followed by a short narration (explanation) in brackets.

Example entries:

  • Started business with cash ₹1,00,000:
    • Cash A/c ........ Dr 1,00,000
    •   To Capital A/c ........ 1,00,000
    • (Being business started with cash)
  • Purchased goods for cash ₹20,000:
    • Purchases A/c ... Dr 20,000
    •   To Cash A/c ........ 20,000
  • Sold goods on credit to Ram ₹15,000:
    • Ram A/c ........... Dr 15,000
    •   To Sales A/c ....... 15,000
  • Paid rent ₹5,000:
    • Rent A/c ......... Dr 5,000
    •   To Cash A/c ........ 5,000

5. Compound and opening entries

  • A compound (combined) entry records two or more transactions of the same date/nature in one entry (e.g. paid salary and rent together).
  • An opening entry brings forward the previous year's assets, liabilities and capital at the start of a new year (assets debited, liabilities and capital credited).

6. Closing thought

Recording begins with the accounting equation and the rules of debit and credit, backed by source documents/vouchers, and captured as journal entries in the book of original entry. Practise identifying the two accounts and their types for each transaction until it is instant. In the board exam this chapter is a major practical component — journalising and the accounting equation carry substantial marks.

Common mistakes & fixes

These are the exact errors that cost students marks in board exams. Read them once, save yourself the trouble.

WATCH OUT
Reversing debit and credit for capital/liabilities
Capital and liabilities INCREASE on the credit side and decrease on debit — opposite to assets.
WATCH OUT
Recording drawings as an expense
Drawings reduce capital (Drawings A/c Dr, To Cash/Goods) — not a business expense.
WATCH OUT
Debiting the customer's name for a cash sale
For a cash sale, debit Cash; only debit the customer (debtor) for a CREDIT sale.
WATCH OUT
Omitting the narration
Every journal entry needs a brief narration in brackets explaining it.
WATCH OUT
Unbalanced entries
Always check total debit equals total credit before moving on.

Practice problems

Try each one yourself before tapping "Show solution". Active recall > rereading.

Q1EASY· Equation
State the basic accounting equation.
Show solution
Assets = Liabilities + Capital. ✦ Answer: Assets = Liabilities + Capital.
Q2EASY· Rule
Is an increase in an asset debited or credited?
Show solution
Debited. ✦ Answer: debited.
Q3EASY· Document
Name the source document prepared when goods are sold on credit.
Show solution
An invoice/bill (sales invoice). ✦ Answer: invoice/bill.
Q4MEDIUM· Equation effect
Show the effect on the accounting equation: started business with ₹50,000 cash, then bought goods for ₹10,000 cash.
Show solution
Step 1 — Capital introduced: Assets (Cash) 50,000 = Capital 50,000. Step 2 — Goods bought for cash: Cash −10,000, Stock +10,000 → Assets still 50,000 = Capital 50,000. ✦ Answer: equation stays 50,000 = 50,000 (assets rearranged).
Q5MEDIUM· Journal
Pass the journal entry: purchased furniture for cash ₹12,000.
Show solution
Step 1 — Furniture (asset) increases → debit; Cash (asset) decreases → credit. Step 2 — Furniture A/c Dr 12,000; To Cash A/c 12,000 (Being furniture bought for cash). ✦ Answer: Furniture A/c Dr 12,000 / To Cash A/c 12,000.

Q9MEDIUM· Rule
State the debit/credit rule for liabilities and give an example entry.
Show solution
Step 1 — Liabilities increase on credit, decrease on debit. Step 2 — E.g. bought goods on credit from Sohan ₹7,000: Purchases A/c Dr 7,000; To Sohan A/c 7,000 (creditor/liability increases → credit). ✦ Answer: liabilities credited on increase; Purchases Dr / To Sohan.

Class 12 AccountancyHigh — builds directly on this

Questions students ask

The real ones — pulled from the Q&A community and tutor sessions.

Yes — it follows the NCERT Accountancy textbook, so recording rules are common across CBSE and most state boards (including RBSE); each board sets its own exam pattern.

Identify the two accounts affected and their type. Assets and expenses are debited when they increase; liabilities, capital and income are credited when they increase — and total debit must equal total credit.

For a cash sale you debit Cash; for a credit sale you debit the customer (a debtor). Both credit the Sales account.

The narration briefly explains the transaction, making the entry understandable and verifiable — supporting the objectivity and full-disclosure principles.
