Core concepts

01Journal: book of original entry; chronological record of transactions with narration.
02Ledger: classified summary; T-account with debit and credit sides.
03Posting: transferring journal entries to respective ledger accounts.
04Trial Balance: list of debit and credit balances; arithmetical accuracy check.
05Three rules: Personal A/c (Debit receiver), Real A/c (Debit what comes in), Nominal A/c (Debit expense/loss).

Flowchart summary

Transaction | v Journal (entry + narration) | v Ledger (T-accounts, balanced) | v Trial Balance (Dr = Cr ?)

Exam-critical pointers

⭐Errors not disclosed by trial balance: error of omission, principle, compensating errors.
⭐Suspense A/c absorbs trial-balance mismatches temporarily.
⭐Compound journal entries combine multiple debits/credits but must balance.
⭐Subsidiary books (purchase, sales, returns, cash) avoid bulky journalising.

Journal, Ledger and Trial Balance

📝

Journal Entry

→Book of original entry; chronological record with date, accounts, amounts, narration.
→Compound entries combine multiple debits/credits; total debits must equal credits.
→Subsidiary books (purchase, sales, cash, returns) reduce journal volume.

📊

Ledger Accounts

→T-account format: debit side (left), credit side (right).
→Posting transfers journal entries to respective accounts by classification.
→Closing Balance = Opening Balance + Increases − Decreases.

⚖️

Three Golden Rules

→Personal A/c: Debit the receiver, credit the giver.
→Real A/c: Debit what comes in, credit what goes out.
→Nominal A/c: Debit all expenses/losses, credit all incomes/gains.

✓

Trial Balance

→List of debit and credit balances from all ledger accounts.
→Arithmetical check: Total Debits must equal Total Credits.
→Errors of omission, principle, and compensating errors not disclosed by trial balance.
→Suspense A/c temporarily absorbs trial-balance mismatches for investigation.

🔄

Posting Process

→Transfer journal entry amounts to debit/credit sides of respective T-accounts.
→Ensures classified record of transactions by account.
→Balance accounts before preparing trial balance.

Explained simply

Imagine you have a piggy bank and you want to remember every coin you put in. A journal is like your special notebook where you write down every single thing you do with money, in order. Today you got five coins from mom, tomorrow you spent two coins on candy. You write it all down with the date and why. That's a journal! 📓

Why does this matter? If you don't write things down, you forget what happened. Then you can't check if you still have the right number of coins. Big stores and accountants need to remember thousands of things, so they write everything in a journal first.

Here's how it works. You run a lemonade stand. Day 1: you buy cups for 10 coins and write "June 1 — bought cups, cost 10 coins." Day 2: you sell drinks for 20 coins and write "June 2 — sold lemonade, made 20 coins." Your journal is like a story of everything. Next, you copy each thing into a ledger—which is like sorting your journal into boxes. All cup costs go in one box, all sales money in another. Then you add up each box and check: did money come in and go out equally? That check is the trial balance! ✓

Real grown-up accountants do exactly this every day. They write everything in order (journal), sort it by type (ledger), then check their math works (trial balance) before telling anyone how much money the business truly has.
