Purchase Day Book in Accounting 

In the scope of accounting, accounts of primary entry and accounts of secondary entry are the two types of accounts. Among the books of primary entry, we have some specialized books, and we name these as subsidiary books. Among these subsidiary books, a very important kind is the purchase journal or the purchase day book. There are several types of purchase day books namely purchase journal, purchase day book, the book of the invoice, bought book, etc. It is an original entry book. This article will look into the definition, the format of purchase day book, advantages of purchase day book, solved examples, etc. 


Meaning of Purchase Day Book 

The purchase day book is a subsidiary book that records those credit purchases of a firm, which the firm shall resell. Therefore, no cash transactions are a part of a purchase journal. Such trades are a part of the cash book. Any transaction which the business doesn't mean to resell is not made a part of the purchase book. 


For instance, a piece of machinery purchased on credit will not find a place in the purchase book but rather in a journal. When the accountant records all the entries properly, he/she calculates the total at the end of a week or month. This value shows the total amount of credit transactions for that specific period. This amount of money gets debited from the purchase account of the firm, and the credit goes to the accounts of the sellers individually.

One can also put in other details like the number of goods bought or the price of the goods, etc. The third column reads L.F., which refers to 'ledger folio' and the consecutive one is for the invoice number. These details are solely for reference information, as in the method of manual accounting, cross-referencing is an important element.
