Purchase Book � Detailed Functional Guide

Introduction

The Purchase Book is a primary accounting register used to record all credit and cash purchases made by the business. It captures details of vendor transactions, purchase amounts, taxes, and ledger postings, helping maintain transparency and control over procurement expenses. This register acts as the first record before data flows into ledgers, trial balance, and financial statements.

Purpose of the Purchase Book

The key objectives of maintaining a Purchase Book are:

• To systematically record every business purchase.
• To track vendor liabilities and payment obligations.
• To ensure every purchase entry has a matching accounting posting.
• To maintain accurate and auditable procurement records.
• To support smooth preparation of purchase-related reports and financial statements.

Role in Accounting Workflow

The Purchase Book serves as a foundational input to:

• Ledgers for supplier account balancing.
• Trial balance for debit and credit summaries.
• Expense tracking and cost calculations.
• GST and statutory reporting (if applicable).
• Overall financial statements.

Accurate data in the Purchase Book ensures that all downstream reports reflect the correct figures.

Accessing the Purchase Book

You can open the Purchase Book from the accounting section:

1. Navigate to Accounting Books.
2. Select Purchase Book.
3. Choose the desired date or period.
4. Apply the filter to load the records.

The system will display all business purchase entries for the selected time frame.

Information Displayed in the Purchase Book

Each transaction includes complete details needed for financial verification. Typical fields include:

• Purchase date
• Invoice or reference number

Filtering and Search Options

The Purchase Book supports powerful filters to refine the report:

• Date or date range
• Vendor or ledger selection
• Invoice number or reference search
• Purchase type (cash, credit, expense, etc.)

These filters help locate specific transactions, such as purchases from a single vendor or purchases on a particular date.

Drill-Down into Purchase Records

Most systems support drill-down, allowing you to:

• Open the original purchase voucher or invoice.

• Check ledger postings related to the entry.

This is especially useful during:
