A packing slip, also called packing list, is a document that is delivered with the products to inform all parties, including transporters, government workers, and customers, about the contents of the package. It's also helpful to let them know how to deal with the package accordingly. A price list can also help the recipient to check if there are some products missing in the transportation. If you are planning to create a packing slip, a proper template can help you get a good start.
