This document provides information about cash books. It begins by explaining that as a business grows and the number of transactions increases, recording all transactions in a single journal becomes inconvenient. Various books are then maintained to record transactions according to their nature, such as a cash book for cash transactions.
The document goes on to describe what a cash book is - it is a book where all cash receipts and payments are recorded. It then explains the different types of cash books, including simple cash books which record only cash receipts and payments, and bank column cash books which have an additional column to record bank transactions. The formatting and posting process for each type is outlined.
