What is the name of the book of original entry used specifically for recording purchases of merchandise on credit?

The book of original entry used specifically for recording purchases of merchandise on credit is known as the purchase journal. This specialized journal is designed to track all credit transactions related to purchases, ensuring that they are systematically recorded. Each entry in the purchase journal includes details such as the date of the purchase, the vendor, the amount, and any applicable terms of credit. This method of documentation is essential for accurate financial reporting and helps businesses manage their accounts payable effectively.

The sales journal is used to record sales made on credit rather than purchases, while the cash receipts journal focuses on cash transactions. The general journal serves a broader purpose, capturing various types of financial transactions that do not fit neatly into other specific journals. By using the purchase journal, businesses can streamline their accounting process and maintain clear records of outstanding credit purchases.
