Final answer:
To ensure correct items and quantities have been received, compare the delivered items with the packing slip and then compare the slip with the purchase order.
Step-by-step explanation:
When determining if the correct items in the correct amounts have been received, it is essential to perform a two-step verification process. Initially, the items delivered should be compared with the packing slip that accompanies the delivery. This step ensures that the received items match what was intended to be sent according to the document. The second step involves comparing the packing slip with the company's purchase order.
The purchase order is a document that contains detailed information about the items ordered, including types, quantities, and prices, and represents a formal agreement between the buyer and seller. By comparing the received items to both of these documents, you can ascertain if the correct goods were provided in the right quantities and identify any discrepancies.
