Final answer:
The store room employee should compare items received from a purveyor to the purchase order to confirm accuracy in delivery and quantities before checking other documents like invoices.
Step-by-step explanation:
When a store room employee receives orders from a purveyor, they should first check the items received against the purchase order. The purchase order is an official document issued by the buyer to the seller, detailing the types, quantities, and agreed prices for products or services. It is important to check the items against the purchase order to ensure that what was ordered is indeed what was delivered, in the correct quantity, and at the agreed-upon price. An invoice is also used in the process, but it is generally compared after the initial receipt of goods is confirmed to match the purchase order. Using the correct document for comparison avoids issues such as receiving the wrong items or incorrect quantities, thus ensuring the inventory records remain accurate and discrepancies are addressed immediately.
