What is a sales journal?

Copy link to section

A sales journal, also known as a sales day book, is a specialized accounting ledger used to record all credit sales transactions made by a business. This journal serves as the first point of entry for these transactions before they are posted to the general ledger.

The primary purpose of the sales journal is to keep a detailed and organized record of each sale made on credit, ensuring accurate tracking and reporting of revenue.

In bookkeeping, the sales journal is similar in form to the purchase journal, but it specifically deals with sales on credit rather than purchases. Each entry in the sales journal typically includes details such as the date of the transaction, the invoice number, the customer’s name, and the amount of the sale.

How does a sales journal work?

The sales journal works by providing a systematic way to record and track credit sales transactions. When a sale is made on credit, the details of the transaction are entered into the sales journal. This entry serves as the initial record of the sale, capturing all relevant information for future reference and reporting.

Each entry in the sales journal includes several key pieces of information:

  • Date: The date when the credit sale was made.
  • Invoice number: A unique identifier for the transaction, linked to the sales invoice.
  • Customer name: The name of the customer to whom the sale was made.
  • Description: A brief description of the goods or services sold.
  • Amount: The total amount of the sale, including any applicable taxes.

Posting to the general ledger

After transactions are recorded in the sales journal, they are periodically posted to the general ledger. This process involves summarizing the total credit sales for a specific period and transferring these amounts to the relevant accounts in the general ledger.

This ensures that the business’s financial records are up-to-date and accurately reflect all credit sales.
