Which of the following is a data-entry best practice when processing orders?

• A. Enter orders as quickly as possible without checking details.
• B. Only check item codes, ignore customer details.
• C. Skip verification to save time.
• D. Double-check item codes and quantities; verify customer details and delivery instructions.

Answer: (D)

Thorough verification of all order details is essential. Double-checking item codes and quantities ensures the warehouse picks the correct products in the right amounts, avoiding wrong items or short shipments. Verifying customer details confirms the correct recipient and contact information, and reviewing delivery instructions handles any special notes or timing needs. When every part of the order is checked before processing, you prevent errors that can lead to misdeliveries, billing mistakes, delays, and unhappy customers, and you support smoother fulfillment and traceability. Rushing or skipping verification—such as only checking one data field or ignoring adjustments—raises the risk of costly mistakes and operational disruptions. So the best practice is to confirm item codes, quantities, customer information, and delivery instructions before finalizing the order.
