|---|---|---|
| Owner invests ₹1,00,000 cash | Cash ↑, Capital ↑ | A ↑ = L + C ↑ ✔ |
| Purchase machinery for ₹30,000 cash | Machinery ↑, Cash ↓ | A ↑↓ (net 0) = L + C ✔ |

- Identify the accounts affected — which accounts change due to this transaction?

- Apply the Golden Rule — decide which account to Debit and which to Credit.
- Record in Journal format — Debit account first, Credit indented with "To", then narration.
- Verify — Total Debit amount = Total Credit amount.
Narration is a brief explanation of the transaction written in brackets below each journal entry.

⚡ Rapid-Fire Exam Checklist
- The Accounting Equation always balances — if it doesn't, an error exists.
- Journal is the Book of Original / Prime Entry — not the Ledger.
- Narration begins with "Being …" and is written in brackets.
- The debit account is written first; credit account is indented with "To".
- Total Debits must always equal Total Credits in every entry.
- Goodwill is an intangible Real Account — not Nominal.
- Capital A/c is a Representative Personal Account — not Nominal.
- L.F. column is filled after posting, not during journalising.
- Purchases Return A/c = Returns Outward A/c.
- Sales Return A/c = Returns Inward A/c.
- Crediting Cash A/c when bank is used (and vice versa).
- Confusing Sales A/c with Cash A/c in cash sales.
- Forgetting to write narration — marks are deducted.
- Calling Goodwill a Nominal Account — it is a Real Account.
- Writing "To Cash A/c Dr." — the "Dr." appears only on the Debit line.
