Definition of a Cash Book

A cash book is a dedicated accounting ledger used to record all cash transactions—receipts and payments—in chronological order. In Canadian accounting, the cash book serves as both a journal and a ledger for tracking cash movements. Small businesses or bookkeepers often maintain it daily or weekly.

For example, a retail shop in Regina might keep accurate daily cash balances by recording all-cash sales, supplier payments, and petty cash expenses in a cash book.

Purpose of a Cash Book in Business and Accounting

The cash book plays a crucial role in managing and monitoring business cash flow:

1. Accurate Cash Tracking – Records real-time inflows and outflows of cash.
2. Internal Control – Helps detect errors or discrepancies in cash handling.
3. Audit Preparation – Acts as a source document for verifying transactions during financial audits.
4. Simplifies Reconciliation – Aids in comparing cash balances with bank statements.
5. Supports CRA Compliance – Provides verifiable records for tax reporting and GST/HST filings.
