What is a cash book? Explain the importance of cash book.

Cash Book

A cash book is a subsidiary book of account that records all cash and bank transactions of a business in a chronological order. It is a specialized journal that helps in maintaining a complete and accurate record of cash receipts and payments. The cash book is usually ruled with two money columns (one for cash and one for bank) and sometimes with additional columns for discounts, bank charges, and other related items.

The cash book is prepared based on the dual-entry system, meaning every transaction affects both the debit (receipts) and credit (payments) sides. It serves as the primary source for posting entries into the ledger accounts for cash and bank.
