Which document confirms delivered items against the purchase order and provides traceability?

• A. Delivery note
• B. Packing slip
• C. Invoice
• D. Receipt slip

Answer: (B)

The packing slip is the document that accompanies a shipment and lists the exact items, quantities, and often the item numbers or PO reference. It lets receiving staff verify that what arrived matches what was ordered on the purchase order, item by item, creating a traceable record from the order to the delivered goods. This traceability is crucial for inventory control and for resolving any discrepancies later, such as shortages or overages.

Other documents serve different purposes: a delivery note mainly signals that the goods were delivered, but may not provide a detailed, itemized match to the PO; an invoice is focused on billing and payment rather than confirming receipt against an order; a receipt slip is not typically used for documenting purchase-order–to–delivery reconciliation.
