In this lesson, we discussed the documents needed when receiving work deliveries, focusing on the delivery note, packing slip, and purchase order. The packing slip is essential as it provides a detailed list of products included in the package and verifies that everything matches the order, which is especially important for international deliveries. We emphasized the importance of accurate address details on all documents to ensure smooth processing. Properly filling out these documents can facilitate the workflow and help with checks by customs authorities.
