Record transactions in ledger (T) accounts using the double-entry principle

What this dot point is asking

SEAB wants you to record transactions in ledger accounts drawn as T-accounts, applying the double-entry principle so the books balance. The central insight is the dual effect: every transaction is entered as a debit in one account and a credit in another for the same amount, and each entry names the other account so the pair can be traced.

The answer

The layout of a T-account

A ledger account is drawn as a capital T. The account name sits at the top; the debit entries go on the left, the credit entries on the right:

| Account name (debit side) | $\

Each line shows the date, the name of the other account in the double entry (the cross-reference), and the amount.

The dual effect

Every transaction affects two accounts. One account is debited and the other credited by the same total. For a cash sale of \300$, cash (asset) goes up so it is debited, and sales (income) goes up so it is credited. Because the two entries are equal, total debits always equal total credits.

Cross-references (the narrative)

In each account, the entry names the other account involved. In the cash account, the \300$debit is labelled "Sales"; in the sales account, the$\$300$ credit is labelled "Cash". This points the reader to the matching half of the entry and makes the double entry easy to trace and check.

Contra entries

When both sides of a single transaction appear in the cash book (for example, cash banked: cash down, bank up), the matching entries are marked with the letter C for "contra", showing that the two halves are within the same book.

Examples in context

Example 1. Banking cash takings. A shop pays \1,000$ of cash takings into the bank. Cash (asset) falls, so it is credited; bank (asset) rises, so it is debited. Because both entries sit in the cash book, each is marked "contra" (C). The dual effect still holds: one debit, one equal credit.

Example 2. Buying on credit then paying. A trader buys goods \2,000$on credit (Debit Purchases, Credit the supplier), then later pays by cheque (Debit the supplier, Credit Bank). Across the two events the supplier's account is first credited then debited by$\$2\,000$, leaving a nil balance once paid, which the cross-references make easy to follow.

Try this

Q1. Draw the heading of a T-account and state which side is debit and which is credit. [2 marks]

• Cue. The account name sits on top; the debit side is on the left, the credit side on the right.

Q2. Post a cash sale of \400$ to the two relevant accounts, with cross-references. [2 marks]

• Cue. Cash account: debit \400$labelled "Sales". Sales account: credit$\$400$ labelled "Cash".

Q3. Explain why a cross-reference names the other account in the double entry. [2 marks]

• Cue. So the reader can trace the matching half of the entry in the other account and check that the double entry is complete.
