The two most common journals used to record transactions in a business are the Sales Journal and the Purchases Journal.
The business that is issuing the source document, such as an invoice or a sales receipt, will record the transaction in the Sales Journal. The Sales Journal is used to record sales made on credit.
The business that is receiving the source document, such as a purchase order or a supplier's invoice, will record the transaction in the Purchases Journal. The Purchases Journal is used to record purchases made on credit.
Both journals are used to track and record transactions related to the sale and purchase of products or services. They are important tools for businesses to keep accurate records of their financial transactions.
