You enter a supplier invoice for a purchase order that has already been delivered. Apart from the purchase order number, what other information can you use as a reference?

The bill of lading number serves as a useful reference when entering a supplier invoice because it is a document issued by a carrier, which provides details about the shipment of goods. The bill of lading essentially acts as a receipt for the merchandise and often includes important information such as the type of goods, their quantity, and delivery instructions. This reference can help streamline the verification process when matching the supplier invoice with the details of the purchase order and the delivered goods, ensuring that the invoiced items align with what was actually received.

In contrast, while the other options may contain helpful information related to the logistics or contact specifics, they do not provide as direct a link to the actual shipment details involved in the invoice process as the bill of lading number does. For instance, the delivery note number is relevant but is also tied more to the shipment's receipt process rather than the invoice reconciliation itself. Supplier contact details and shipping dates, while useful in certain contexts, do not directly correlate with the transaction and verification of received goods as effectively as the bill of lading number.
