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

The invoices or bills provided to consumers are the source papers for recording entries in the sales book.
