Packing slip vs invoice
The packing slip tells the person at the bench, and the person opening the box, what should be inside. The invoice tells a accounts team what is owed, with tax, payment terms and a legal entity. Mixing the two can leak a gift’s price, or leave a wholesale order without a proper bill.
Some marketplaces generate both from the same order. If you already get a complete slip from Shopify, Etsy or ShipStation, you may not need this page. Use it when you pack a manual order, a craft-fair leftover, or a channel that does not print a slip you like.
