Recording of Transactions I Class 11 Notes

This is the first computational chapter, and everything the rest of the syllabus depends on. You take a document, find its effect on the accounting equation, convert that effect into a debit and a credit, and write the entry in the journal. Master the three rules of debit and credit here and every later chapter becomes routine.

Key Concept Summary

What is the rule for a personal account?

Debit the person who receives value and credit the person who gives value. This produces the two memorable rules: debit the receiver of value, and credit the giver of value. Because a personal account's debit balance is what the person owes the business, the rule is simply the mirror image of the reality.

01

Business Transactions and Source Documents

A business transaction is any event that changes the assets, liabilities, capital, revenue or expenses of the business. Cash is not necessary: a credit purchase of machinery is a transaction even though no cash moves, and the only test is whether the accounting equation is affected.The source document is the original evidence of the transaction — a bill, a receipt, a cash memo, a bank statement, a debit note, a credit note or a payslip. It is the authority for the entry, and the accountant must see it before recording anything.

  • Cash memo: issued when cash or goods are received, showing the party, the amount and the period for which payment is made.
  • Bill: a document of indebtedness, used when a sale or purchase is on credit.
  • Debit note: issued by the seller to reduce the amount of a bill or invoice already issued.
  • Credit note: issued by the seller to increase the amount of a bill or invoice already issued.
  • Receipt: acknowledges payment received in full or part.
  • Pay-in-slip: the deposit slip accompanying cash or cheque into the bank.

Vouchers are not source documents

A source document is the external evidence, such as a bill or a receipt. A voucher is the internal document prepared from it, containing full particulars and the ledger folios, and it is the voucher that authorises and records the entry. Every source document must be supported by a voucher, but the two are not the same thing, and CBSE asks about the difference repeatedly.
02

The Accounting Equation and Analysing a Transaction

The equation of a business is the statement of its financial position at every moment. The two sides are always equal because every transaction has two aspects: it affects the assets and the capital on one side, and the accounting equation cannot be disturbed, only rearranged.

  • Transposition of an equation within the equation: a transaction affecting two assets, such as cash received from the debtor, changes the structure but not the total.
  • Change of one asset into another: the value moves, the total of assets is unchanged.
  • Change of one liability into another: a creditor is settled partly by cash and partly by issuing a bill, so total liabilities are unchanged.
  • Increase of an asset and a capital: the owner introduces capital, or a revenue item is earned.
  • Increase of an asset and a liability: a liability is incurred to buy an asset, for example purchasing machinery on credit.
  • Increase of an expense and a decrease of an asset: an expense is paid in cash.
  • Increase of an asset and a decrease of a liability: a debtor pays what was owed.

How to answer an analysis question in three columns

Write a table with the transaction, then the effects on assets and on the capital, liabilities and revenue separately. State whether the total of the left-hand side has changed and whether the total of the right-hand side has changed, and note that the equation holds in every case. CBSE awards the marks for the two effects and the closing statement, so do not skip the last one.
03

Rules of Debit and Credit

The debit and credit rules are the two aspects of every transaction restated in a fixed form. They are not arbitrary: the debit side of every account is the left-hand side of that account, and the debit of a real account is always an asset.

  • Real account (assets): debit what comes in, credit what goes out — the rule is debit the receiver, credit the giver.
  • Personal account (persons): debit the receiver of value, credit the giver of value. The debit balance of a personal account is the amount that person owes.
  • Nominal account (expenses, incomes, profits and losses): debit all expenses and losses, credit all incomes and gains — the rule is debit what goes in, credit what comes in, the reverse of the real account.
  • The golden rule: put every credit of one account into the debit of another.

The single most common error in the chapter

Do not apply 'debit the receiver' to nominal accounts. For an expense, what goes in is debited and what comes in is credited, which is the opposite of a real account. The three rules are not variations of one rule; the nominal account deliberately runs the other way, and mixing them up loses the easiest marks in the paper.
04

Journal and the Format of a Journal Entry

The journal is the book of original entry, where every transaction is recorded chronologically, once, in debit and credit form, with a narration explaining the purpose. Recording only the essential details of a transaction rather than every part of it is called narrating, and a journal entry is not complete without it.

  • Date, followed by particulars, followed by folio (the ledger page number).
  • The account to be debited is written on the first line with the amount in the debit column and a folio against it.
  • The account to be credited is written on the second line with the amount in the credit column and a folio against it.
  • A short narration in brackets follows the credit line, after a 'Being' connective.
  • The amount is written in the first money column and the total is written under both columns and underlined twice.
  • The balance of cash and bank is shown below the balance line with the date.

Two rules for the narration

A narration begins with the word 'Being', and it explains what the transaction is, never which accounts are involved. 'Being goods purchased from Ram for Rs. 40,000' is correct; 'Being Ram account debited with goods' is not. Write the narration in the present tense and keep it to one line, because the marks are for the entry and not the prose.
05

Worked Entries — the Six Common Cases

Nearly every journal entry in this chapter is one of six patterns. Learn them as pairs of accounts and the analysis becomes routine, because the only work left is finding the amount and naming the narration.

  • Cash A/c Dr, To Capital — the owner introduces cash into the business. Effect: an asset and capital both increase.
  • Cash A/c Dr, To Sales — cash is received for goods sold. Effect: an asset increases, revenue increases.
  • Cash A/c Dr, To Debtors — a debtor settles the amount owed. Effect: one asset replaces another, so the total is unchanged.
  • Bank A/c Dr, To Cash A/c — cash is deposited into the bank. Effect: a transposition within assets, which is why the cash book records it in one entry across two columns.
  • Purchases A/c Dr, To Creditors — goods are bought on credit. Effect: an expense and a liability both increase.
  • Drawings A/c Dr, To Cash A/c — the owner withdraws cash for personal use. Effect: capital falls, no expense arises.

Goods withdrawn by the owner

When the owner takes goods for personal use, the entry is Drawings A/c Dr and Purchases A/c Cr, valued at the cost of the goods. The same pair appears in Chapter 9 as an adjustment, where it increases purchases and the closing stock rises by the same amount, so purchases are in fact overstated by twice the value if the adjustment is missed. This is the one entry that is examined more often than any other in the chapter.
06

The Ledger and Posting from the Journal

The ledger is the principal book of account, containing all accounts in alphabetical order, with columns for particulars, folio, amount and a running balance. The journal gives the full story of each transaction; the ledger collects all entries for one account together, which is what makes a balance possible.

  • Posting rule: for each journal entry, the amount is entered in the appropriate account with the journal folio in the folio column, on the same line as the particular.
  • Amounts on the debit and credit sides are posted on the same date line; a line is ruled on both sides when the two postings fall on different dates.
  • Posting from the sales, purchases and returns books is made daily, with the particulars column showing the invoice or bill number, and the debit and credit are posted to their respective accounts.
  • Balance of an account: for an asset or expense, a debit balance; for a liability, income or capital, a credit balance. The balance is entered on the last line and the account is ruled off.

Ruling off an account correctly

For an account with a debit balance, add a further line at the bottom, rule the account off, then write the balance c/d on that line and bring the opening balance b/d down to the top of the next page. For a credit balance the two lines are reversed. Getting this wrong is the most common reason for losing the final mark in a full-ledger question.

Exam Strategy

How this chapter is asked

High-yield question patterns observed across CBSE boards, JEE Main & Advanced, and NEET.

  • Every journal entry is examined for the debit account, the credit account, the narration and the ledger folios. All four carry marks, so an entry with a wrong narration loses a mark even when the debit and credit are right.
  • The account to be debited is always written first, with the ledger folio in the folio column; the credit follows on the next line. Reversing the two is a standard and avoidable deduction.
  • For a transaction question, do not jump straight to the journal. First state the effect on the accounting equation, then give the entry. The analysis earns the conceptual mark and the journal earns the computational one.
  • Purchases made on credit increase both an asset and a liability, never an expense at the time of purchase. The expense appears only as cost of goods sold in Chapter 8.
  • When goods are taken for personal use by the proprietor, the entry is Drawings Dr and Purchases Cr. It is the one personal-account entry that touches a nominal account, and students lose the mark by crediting purchases instead.
  • Discount allowed is an expense of the seller, so it is debited; discount received is an income of the buyer, so it is credited. Trade discount is never recorded at all.
  • In the ledger, keep the debit and credit sides aligned on one line and continue the running balance. A ledger with a blank date line is marked wrong even if the figures are correct.
  • For a debit balance, the balance c/d is written on the credit side of the account and the balance b/d appears on the debit side of the next page. Reversing these two is the classic last-mark error.

FAQ

Frequently asked questions

What is the difference between a source document and a voucher?

A source document is the external evidence of a transaction, such as a bill, a receipt or a bank advice, and it is issued by the other party or by the bank. A voucher is the internal document prepared by the accountant from that source document, containing full particulars of the transaction and the ledger folios, and it is the voucher that authorises the entry in the books. A voucher is prepared for every source document, and it is the voucher, not the source document, that forms part of the accounting record.

Why is the accounting equation called the backbone of accounting?

Because every transaction, whatever its form, has two aspects and the equation shows both of them. The equation cannot be disturbed by a transaction, only rearranged, which is why the total of debits always equals the total of credits and why a trial balance agrees. It also classifies the effect of each transaction into one of a small number of types, and the analysis question in this chapter is simply a request to name which type applies.

How do I decide whether an account is debited or credited?

First identify the type of account. For a real account, debit what comes in and credit what goes out. For a personal account, debit the receiver of value and credit the giver of value. For a nominal account, debit all expenses and losses and credit all incomes and gains. If you are unsure, remember that the debit side is always the left-hand side of a T-account, and a debit balance in the ledger means the account still has a value in the business, which is true of assets, debtors, drawings and expenses.

What is the difference between the journal and the ledger?

The journal is a chronological record in which every transaction appears once, with its debit, credit and narration. The ledger is a classified record in which all entries relating to one account are brought together, so a balance can be struck. Posting transfers the journal entry into the relevant ledger accounts, and the folio columns in both books allow the two to be traced in either direction.

How is the balance of an account carried forward?

For an account with a debit balance, the difference between the totals of the two sides is entered as balance c/d on the credit side after the account is ruled off, so that both sides are equal. The same figure is then entered as balance b/d on the debit side at the top of the next page. For a credit balance the two are reversed. The point of the two entries is that the account totals agree while the balance continues.
