1Concept Briefing

This is the most thorough briefing in the lab — read it once carefully. Every one of the eight journal-entry types below appears in the Guided and Independent stages ahead.

The Double Entry Principle

Every transaction affects at least two accounts — one receives value, one gives it up. Recording both sides is what makes the system "double entry."

The Three Types of Accounts

The Eight Types of Journal Entries

Real businesses don't only record simple, one-debit-one-credit transactions. Below is every major category you'll practise in this lab.

1. Simple Entry

The most basic form — exactly one account debited and one account credited.

Cash (Real A/c) is coming in → Debit. Capital (Personal A/c) — the proprietor is the giver → Credit.

2. Compound Entry

A single transaction that involves more than two accounts — either multiple debits, multiple credits, or both — because one event triggers several simultaneous effects. When more than one account appears on either side, the other side's particulars column is conventionally written as "Sundries" or lists each account with "To"/"By" on its own line.

3. Opening Entry

Made on the first day of a new accounting year to bring forward every asset, liability, and capital balance from the previous year's closed books into the new year's ledger. All assets are debited, all liabilities and capital are credited — it is really a special case of a compound entry.

4. Adjustment Entry

Made at the end of an accounting period so that financial statements reflect the correct position on an accrual basis, not just cash actually received or paid. The four most common adjustments:

5. Closing Entry

Made at year-end to transfer every nominal account (all expenses and all incomes) into the Trading Account or Profit & Loss Account, reducing each nominal account to zero so the new year starts clean.

6. Rectification Entry

Corrects an error already posted in the books. The correcting entry must undo the wrong effect and create the right one — students should ask "what was wrongly done?" and "what should have been done?" and journalise the difference between the two.

7. Bills of Exchange Entry

A Bill of Exchange is a written, signed, unconditional order to pay a fixed sum on a specified date. The three most common events: receiving a bill (debit Bills Receivable), discounting it with a bank before maturity (debit Bank for the discounted proceeds, debit Discount on Bill for the difference, credit Bills Receivable for the full face value — a compound entry), and dishonour (the bill is reversed back to the debtor's personal account if the acceptor fails to pay).

8. Bad Debts & Provision for Doubtful Debts

Bad Debts is an actual, confirmed loss — a specific customer will definitely never pay. Debit Bad Debts A/c, Credit the customer's personal account, removing it from the books entirely. Provision for Doubtful Debts is different — it is a prudent estimate (commonly a percentage of total debtors) set aside for debts that might turn bad in future, without removing any specific customer's account. It is created by debiting Profit & Loss A/c and crediting Provision for Doubtful Debts A/c.

What "Ledger Posting" Means

A journal records transactions chronologically, in one combined book. A ledger reorganises the exact same information account by account, so you can see the complete history and running balance of any single account — Cash, Suresh, Sales, whichever you need. Posting is the act of transferring each line of a journal entry into its own account's ledger (T-account). In Stage 4, you will keep the full Journal Book visible and choose any account you like to prepare its ledger — exactly as a real accountant works, with the day book open beside the ledger.
