Date: January 5, 2024
Customer: XYZ Corporation
Invoice Number: INV12345
Amount: $5,000

This entry captures the necessary details about the credit sale. At the end of the accounting period, all entries in the sales journal are totaled and posted to the sales account in the general ledger, ensuring an accurate reflection of the business’s sales activities.
