Operational Aspects of Accounting Entries
(How Banks Do Accounting DIFFERENTLY From Normal Businesses!)
In Chapter 3 you learned: first write in the Journal, then post to the Ledger. But BANKS do it BACKWARDS! Banks post to the LEDGER first (customer accounts must be updated instantly!) and then write the journal/day book later. This chapter explains why and how banks handle their accounting differently.
Banky Discovers Banks Do It Backwards! 🔄
On his first day at the counter, Banky processes a cash deposit. The CBS system instantly updates the customer’s account (ledger). But Banky says “Wait, shouldn’t I write in the journal FIRST?” His senior laughs: “In a bank, we update the customer’s account FIRST — they can’t wait! The journal comes later.”
Why is This Chapter Important?
Exam Marks
2–3 questions on voucher types, ledger-first system, cash vs transfer transactions, GL trial balance. Easy marks!
Daily Work
Every transaction you process follows this system. Understanding the flow helps you trace errors, balance books, and handle audits.
Career Growth
When you become a manager, you’ll sign vouchers, verify day books, and ensure the GL trial balance tallies. This is operational banking!
What Will You Learn?
Key Words — Banking Language Made Simple
In a normal business: Journal (diary) → Ledger (account book). Write in the diary first, then organise into accounts.
In a bank: Ledger (customer account) → Day Book (journal). Update the customer’s account FIRST — because the customer is standing at the counter waiting! Then, at the end of the day, compile all entries into the day book. The day book totals are posted to the General Ledger (GL) control accounts.
Why? A bank cannot afford to keep customer accounts outdated. Imagine a customer deposits ₹50,000 and then immediately wants to withdraw ₹30,000. If you haven’t updated the ledger yet, the system shows insufficient balance! So banks MUST update ledgers in real-time.
In a bank, no accounting entry can be passed without a voucher. It’s the PROOF and AUTHORITY for every transaction. In manual operations, every voucher must be authenticated by an authorised officer. In computerised (CBS) systems, the staff enters the transaction and the officer authorises it digitally — the system automatically creates the voucher and posts it.
3 types of vouchers:
(1) Debit Vouchers: Evidence for DEBITING an account. Examples: customer’s cheque (debits their account), withdrawal slip, salary cheque issued by bank, drafts from other branches.
(2) Credit Vouchers: Evidence for CREDITING an account. Examples: pay-in-slips (deposit), applications for term deposits, challans for govt payments, credit advice from other branches.
(3) Composite Vouchers: Contains BOTH debit and credit. Used mostly for internal/non-customer transactions. Examples: bills received for collection, LCs issued, rectification entries. Both debit and credit accounts mentioned on one voucher.
Cash Transactions: Actual cash comes in or goes out. Customer deposits cash → credit customer a/c, debit cash. Customer withdraws → debit customer a/c, credit cash. Recorded in the cash scroll (a running record of all cash received and paid during the day).
Transfer Transactions (Non-cash): No physical cash involved — just account-to-account transfers. Example: Customer A deposits a cheque drawn by Customer B (both at same branch). A’s account is CREDITED, B’s account is DEBITED. No cash moved! Also called “clearing” when between different banks.
Internal accounts: When the bank itself initiates entries (interest payment, locker charges, draft issuance), one side is a customer account and the other is an internal account (like Interest A/c, Draft A/c). On bulk operations (quarterly interest posting to thousands of accounts), the bank prepares a consolidated voucher with a list of all affected accounts attached.
At the end of each day, all voucher summary sheet totals are posted to the General Ledger (GL) control accounts. The GL trial balance is then prepared. In banking terms, this daily exercise is called “Balancing of Books.”
Every two weeks (fortnightly), a detailed trial balance of all personal ledgers (individual customer accounts) is prepared and agreed with the GL control accounts. If they don’t match, there’s an error somewhere that must be found and fixed immediately.
Cross-checking: Entries in personal ledgers are verified by persons OTHER than those who made the entries. This is an internal control measure to catch clerical errors and prevent fraud.
The Full Chapter — Simple Flow
📖 Part 1 — The Bank Accounting Flow (Step by Step)
Step 1 — VOUCHER: Every transaction starts with a voucher (deposit slip, cheque, withdrawal form, bank’s own voucher). In CBS, the staff punches the transaction, officer authorises it.
Step 2 — LEDGER (Customer Account): The voucher is immediately posted to the customer’s account in the subsidiary ledger (SB ledger, CA ledger, loan ledger, etc.). Customer sees the updated balance in real-time.
Step 3 — DAY BOOK (Journal): At end of day, all debit and credit vouchers of each type are totalled on voucher summary sheets. These totals are entered in the day book (journal).
Step 4 — GENERAL LEDGER: The day book totals are posted to the respective GL control accounts (SB Control, CA Control, Loan Control, Cash Control, etc.).
Step 5 — GL TRIAL BALANCE: Total debits of all GL accounts must equal total credits. This daily check = “Balancing of Books.”
📋 Part 2 — The 3 Types of Vouchers (with Examples)
DEBIT VOUCHERS (13 types!): Cheques issued by customers, pay orders issued by bank, withdrawal forms from SB, drafts from other branches payable at our branch, travellers’ cheques for payment, cancelled drafts for refund, standing instruction letters, term deposit receipts for payment/renewal, and more. Basically any document that causes an account to be DEBITED.
CREDIT VOUCHERS (5 types!): Pay-in-slips (cash/cheque deposits), applications for DD/RTGS/NEFT/pay orders, government challans, credit vouchers on bank stationery (locker charges, stamp purchases), credit advice from other branches for collection. Any document that causes an account to be CREDITED.
COMPOSITE VOUCHERS: Cover BOTH debit AND credit. Used mainly for internal/non-customer transactions: bills received for collection, LCs, guarantees, rectification of wrong entries (e.g., debited CA instead of CC → composite voucher to correct: debit CC, credit CA).
🏦 Part 3 — Real Example: Mr. A’s Savings Account
Mr. A has a SB account with opening balance ₹9,000. On one day, he does 5 transactions:
1. Deposits ₹2,000 cash: Credit A’s a/c (₹2,000). Debit Cash a/c. Balance → ₹11,000. This is a CASH transaction (credit voucher = pay-in-slip).
2. Deposits ₹5,000 cheque from Mr. B (same branch): Credit A’s a/c (₹5,000). Debit B’s a/c (₹5,000). Balance → ₹16,000. This is a TRANSFER (no cash moved — just accounts adjusted).
3. Cheque of ₹3,000 deposited earlier clears: Credit A’s a/c (₹3,000). Debit Clearing House a/c. Balance → ₹19,000. This is a CLEARING entry.
4. Cheque of ₹4,000 issued to Mr. C received in clearing: Debit A’s a/c (₹4,000). Credit Clearing House a/c. Balance → ₹15,000.
5. Purchases DD of ₹6,000: Debit A’s a/c (₹6,000). Credit Draft A/c (internal). Balance → ₹9,000.
The SB Control account in GL reflects the NET effect of ALL SB transactions across ALL customers.
Exam-Ready Points
🎯 Must Remember!
- Banks do LEDGER first, JOURNAL (day book) later. This is OPPOSITE to normal business accounting!
- Reason: Customer accounts must be updated in REAL-TIME. Customer can’t wait for journal entry.
- Voucher Posting: Every entry needs a voucher. Manual = physical voucher + officer’s signature. CBS = digital entry + officer authorisation.
- 3 Voucher types: Debit (money out), Credit (money in), Composite (both debit & credit — mostly internal)
- Cash transactions: Physical cash moves. Recorded in cash scroll. Cash deposit = credit voucher. Cash withdrawal = debit voucher.
- Transfer transactions: No physical cash. Account-to-account. One customer debited, another credited. Also called “non-cash.”
- Day Book totals → GL Control Accounts. GL Trial Balance prepared DAILY = “Balancing of Books.”
- Fortnightly: Personal ledger trial balance prepared and AGREED with GL control accounts.
- Cross-checking: Entries verified by persons OTHER than those who made them. Internal control!
- Consolidated voucher: Used for bulk operations (quarterly interest posting) — one voucher + attached list of accounts.
- CBS: All the above happens automatically. But staff must understand the manual flow for audits and queries.
- Accounting systems differ across banks — different hardware, software, customisation. But the LOGIC is same.
- Software differs between banks = TRUE. “Software does NOT differ” = INCORRECT statement (exam trap!)

Last-Minute Flash Cards
⚡ Chapter 9 Done! Everything in 7 Lines:
- Banks reverse the order: LEDGER first (customer a/c), then DAY BOOK (journal). Because customers can’t wait!
- Every entry needs a VOUCHER: Proof and authority. Authenticated by authorised officer.
- 3 Voucher types: Debit (money out), Credit (money in), Composite (both — mostly internal).
- Cash transactions: Physical money moves. Transfer transactions: Just accounts adjusted, no cash.
- 5-Step Flow: Voucher → Ledger → Day Book → General Ledger → GL Trial Balance.
- “Balancing of Books”: GL Trial Balance prepared DAILY. Personal ledger = fortnightly. Cross-verified by different staff.
- CBS automates everything but follows the same logic. Different banks use different software (exam trap!).
