What to put on a packing slip
A packing slip is a pick-and-pack list, not a tax invoice. At minimum it should carry the shop name, an order number, the date, a ship-to name and address, and each line with a quantity, a SKU and a plain item name. A short note for the box (“gift wrap”, “leave at the door”) saves a second trip to the inbox.
Many shops leave prices off the slip when the parcel is a gift. If you need a priced document, print an invoice separately. Packslip’s free slip is price-free on purpose.
