When should a delivery invoice be signed?

• A. After verifying information against the purchase order
• B. Before delivery
• C. After payment
• D. After vendor confirms shipment

Answer: (A)

Signing the delivery invoice should happen after you verify the items received against the purchase order and the receiving document. This check confirms that the correct items and quantities were delivered at the agreed price and terms, and it gives you a chance to note any discrepancies, damages, or shortages before you authorize payment. This is the three-way match in practice: the purchase order, the receiving record, and the invoice work together to ensure everything aligns. Signing too early—before delivery or before verification—risks paying for incorrect or missing goods, while signing after payment bypasses these checks.
