Book of Original Entry + Ledger Account — A Unique Dual Role
The Cash Book is unique because it serves as both a subsidiary book (book of original entry) and a Ledger account simultaneously. Every cash and bank transaction goes here first. No separate Cash Account or Bank Account is maintained in the Ledger when a Cash Book is in use. Master this chapter and you have mastered the most practical part of bookkeeping.
1. Meaning and Features of Cash Book
A Cash Book is a special purpose subsidiary book used to record all cash receipts and cash payments in chronological order. It is written in a T-format just like a Ledger account — receipts on the Dr. (left) side and payments on the Cr. (right) side.
2. Types of Cash Book
Simple Cash Book (Single Column)
Records only cash transactions. One amount column on each side. Used by very small businesses with no bank account.
Double Column Cash Book
Two columns on each side — Cash and Discount. Records cash transactions plus discount allowed/received. Most common in practice.
Triple Column Cash Book
Three columns each side — Discount, Cash, Bank. Records cash, bank, and discount all in one book. Used by businesses with both cash and bank transactions.
Petty Cash Book
Records small day-to-day expenses (postage, tea, stationery). Maintained by a petty cashier under the Imprest System.
3. Simple Cash Book — Format and Example
The simplest form — one amount column on Dr. side (receipts) and one on Cr. side (payments). Only cash transactions are recorded.

4. Double Column Cash Book (Cash + Discount)
Has two columns on each side — Discount and Cash. The Discount column records trade discount allowed to debtors (Dr. side) and discount received from creditors (Cr. side). The Discount columns are NOT balanced — they are just totalled and transferred to Discount Allowed A/c (Dr.) and Discount Received A/c (Cr.) in the Ledger.

5. Triple Column Cash Book (Discount + Cash + Bank)
Has three columns on each side — Discount, Cash, and Bank. Replaces both the Cash Ledger account and the Bank Ledger account. The most comprehensive form of Cash Book.
Contra Entries — The Most Important Feature
A Contra Entry is an entry that appears on both sides of the Cash Book in the Cash and Bank columns. It occurs when money moves between Cash and Bank within the business. Marked with letter "C" in the L.F. column on both sides. No Ledger posting is done for contra entries.
1. Cash deposited into Bank → Dr. side: Bank column; Cr. side: Cash column. Both entries with "C" in L.F.
2. Cash withdrawn from Bank for office → Dr. side: Cash column; Cr. side: Bank column. Both entries with "C" in L.F.

6. Petty Cash Book — Imprest System
A Petty Cash Book is maintained by a Petty Cashier to record small, recurring day-to-day expenses like postage, tea, stationery, conveyance, etc. The Imprest System is the most common method.
Imprest System — How It Works
Fixed Float Given
Head cashier gives petty cashier a fixed amount at the start of each period (e.g., ₹5,000 per month). This is called the Imprest Amount.
Expenses Recorded
Petty cashier pays and records all small expenses under different heads (Postage, Stationery, Conveyance, Entertainment, Miscellaneous) during the period.
Reimbursement
At the end of the period, head cashier reimburses exactly the amount spent, bringing the balance back to the original Imprest Amount for the next period.
Reimbursement = Total expenses spent during the period (restores to Imprest Amount)
Example: Imprest ₹5,000 | Expenses ₹3,800 | Closing balance ₹1,200 | Reimbursement = ₹3,800
