Features of a Purchase Book

A purchase book or buy book is a special purpose subsidiary book designed to record solely credit purchases of items.

There are two types of accounts: primary accounts and subsidiary accounts. There are unique books called subsidiary books in primary entry books.

A purchase day book’s primary function is to keep track of all corporate credit purchases (meant for resale). This book does not record purchase transactions (in cash) or purchases that are not intended for resale.

A Subsidiary book, sometimes known as a Day book, is a book that contains original entries. The records of comparable transactions are kept in subsidiary books. There are six different types of subsidiary books that an organisation keeps. Cash book, Purchase book, Purchase Return book, Sales book, Sales return book, and Journal paper are the different types of books.

Organizations that don’t keep subsidiary books keep a journal of all their transactions. A journal keeps track of all entries, regardless of their nature. As a result, Journal does not divide entries based on their nature.

Purchase Book

A Subsidiary book is one that is purchased. The Purchase book, also known as the Purchase daybook, keeps track of all credit purchases. The records of all products purchases are kept in the cash book. A buy book does not keep track of asset purchases. Those records are kept in the Journal itself. The entries are made from source documents in the Purchase book. The source documents are invoices or bills obtained from goods providers.

With the invoice’s net amount, we make entries in the Purchase book. As a result, a Purchase book does not include trade discounts or other information found on an invoice. Every month, the sum of the Purchase book is posted to the Purchases A/c Debit side. A/c for purchases is a ledger account. Individual supplier accounts, on the other hand, may be posted on a daily basis. In addition, if the volume of transactions is excessive, the ledger entries might be submitted weekly or fortnightly. The Purchase book’s proforma is as follows:

Date                      Invoice                Name of the                L.F                Amount                       

                                  No.                     Supplier

Return Purchase Book

The Purchase return book is used to track when products purchased on credit are returned to the supplier. Purchased products may occasionally be defective or of poor quality, necessitating their return. Purchase returns are kept in a separate book and are not deducted from the purchases in the Purchase book. Purchase returns are also documented at the invoice’s net amount.

Every return of goods is accompanied by a debit note. It is made in two copies. The original will be forwarded to the supplier, and a duplicate will be stored for our records. The name of the supplier, the details of the products returned, and the reason for the return are all listed on the debit note. Each debit note is serially numbered and dated.

A credit note may also be prepared by the supplier. When items are received from a customer, it is prepared and sent to him. The Purchase Return Book’s performance is listed below.

Date                      Debit Note                Name of the                L.F                Amount                       

                                   No.                           Supplier

Sales Journal

The Sales Book (also known as the Sales Day Book or Sales Journal) is a subsidiary book used to record the sale of items (goods acquired for resale) on credit. It does not record the sale of items for cash or the sale of any asset other than merchandise. The invoices or bills provided to consumers are the source papers for recording entries in the sales book.

After subtracting the trade discount quantity discount, the entries are made with the invoice’s net amount. In the Sales Book, entries are made in the same way as they are in the Purchases Book. The names of the clients to whom items are sold on credit are noted in the ‘Particulars’ Column.
