The Small Change Problem
Meera's kirana store incurs dozens of tiny expenses every day. She buys a packet of envelopes for 20 rupees, pays 15 rupees for a tea delivery, and spends 30 rupees on cleaning supplies. If she records every single one of these 20-rupee transactions in her main double-column cash book, it will become cluttered and massive. How can she separate these minor daily costs without losing track of her main cash flow?
Theory
The Daily Allowance Analogy
Think of the petty cash book like a parent giving a child a fixed weekly allowance. The child tracks how they spend that small amount, and when it runs low, they ask for a refill to reach the original amount again. Meera gives her assistant a fixed 'float' of cash, and the assistant uses this to cover small items, reporting back to maintain the balance.
Theory
The Petty Cash Book & Imprest System
In your university exams, define the Petty Cash Book as a subsidiary book used for recording small, recurring expenses like postage, stationery, and refreshments. It operates on the Imprest System, where a fixed amount (the 'float') is handed to the petty cashier at the start of a period. After spending, the petty cashier is reimbursed the exact amount spent to restore the float to its original balance.

Worked Example: Managing the Float
On April 1, Meera gives her assistant 2,000 rupees as the monthly petty cash float. On April 2, the assistant spends 150 rupees on stationery and 50 rupees on postage.

Recording Petty Expenses
- Step 1: Receive the Float Record 2,000 in the 'Amount Received' column on the debit side.
- Step 2: Record Expenses On the credit side, enter 150 in the Stationery column and 50 in the Postage column.
- Step 3: Reimbursement At month-end, the total spent (200) is reimbursed to the assistant, bringing the cash balance back to 2,000.
Quiz
What is the primary advantage of using the imprest system for petty cash?
- It eliminates the need for any other accounting books
- It maintains a fixed maximum float and ensures petty cashier accountability
- It allows the store to avoid paying taxes on small expenses
Show the answer
It maintains a fixed maximum float and ensures petty cashier accountability
The imprest system prevents the petty cash balance from growing indefinitely and provides a clear audit trail for small costs, ensuring the petty cashier must account for every rupee spent to receive a refill.
Think first
Mental Check: Identifying Petty Items
Meera buys a new high-end refrigerator for 50,000 rupees. Should this be recorded in the petty cash book? Think about the purpose of petty cash before tapping.
Show the answer
No! Petty cash is strictly for small, frequent operational costs. A large asset purchase like a refrigerator should be recorded in the main cash book or the journal, as it is a significant capital expenditure.
Watch out
The Exam Trap: Excluding Totals
Students often forget that the main cash book must still reflect the total cash transferred to the petty cashier. The petty cash book is internal for detail, but the initial transfer of funds from the main cash account to the petty cash 'float' must always be recorded in the main cash book as a credit.
Theory
Connection to Software Logic
In enterprise resource planning (ERP) software, this logic is implemented as a sub-ledger. You don't mix petty transactions with general ledger accounts because you want to keep the main ledger clean for reporting. You aggregate these small transactions into one periodic 'petty cash expense' journal entry to maintain clean records.
Summary
Key takeaways
- The petty cash book manages minor, recurring store expenses to declutter the main cash book.
- It functions on the imprest system, where a fixed float is replenished periodically.
- Analytical columns help categorize petty expenses like postage, stationery, and refreshments.
- The petty cashier must provide vouchers for every payment to justify the replenishment amount.
- Memory Hook: Petty for small, main for big, keep the float and the balance will jig.
