Petty Cash Book.

 A petty cash book is a ledger used to track small cash transactions that occur within a business. This book is used to record expenses that are too small to be recorded in the main accounting system, but that still require some form of record-keeping for auditing and reconciliation purposes.

The petty cash book typically contains the following information:

1. Date of the transaction
2. Description of the expense
3. Amount of the expense
4. Name of the person who received the cash
5. Name of the person who approved the expense

The petty cash book is usually maintained by a designated employee who is responsible for managing the petty cash fund. This fund is a small amount of cash that is kept on hand for small purchases, such as office supplies, postage, or taxi fares.

When a purchase is made using petty cash, the employee records the transaction in the petty cash book and submits the receipt or invoice to the person in charge of the petty cash fund. This person then reimburses the employee for the expense and records the transaction in the petty cash book.

At regular intervals, such as at the end of each month, the petty cash book is reconciled with the petty cash fund to ensure that all transactions have been recorded correctly and that the fund balance is accurate. Any discrepancies are investigated and resolved.

Overall, the petty cash book is an important tool for managing small cash transactions and for ensuring that all expenditures are properly recorded and accounted for.
