Packing Slip Generator

A packing slip is a document included inside a shipped package that lists the contents of the shipment. It tells the recipient exactly what items were packed, in what quantities, and serves as a checklist for verifying that the correct products arrived. Unlike an invoice, a packing slip typically does not include pricing information.

Packing Slip vs Shipping Label vs Invoice

• Packing Slip — An itemized list of the package contents placed inside the box. It helps the recipient verify the shipment and assists warehouse staff during the packing process.
• Shipping Label — The external label affixed to the outside of the package containing the delivery address, return address, tracking barcode, and carrier information. It guides the package through the shipping network.
• Invoice — A financial document sent to the buyer that includes item prices, taxes, totals, and payment terms. It serves as a request for payment and a record of the transaction.

Why Packing Slips Matter for Ecommerce

Packing slips reduce fulfillment errors by giving warehouse staff a clear checklist of what needs to go into each box. They help customers verify their order upon delivery, speeding up the resolution of any discrepancies. For businesses shipping partial orders or split shipments, packing slips clarify which items are in each package and which are still pending. They also support returns processing — customers can reference the packing slip when initiating a return, making the process smoother for both parties.

How Nventory Helps

Nventory automatically generates packing slips as part of your fulfillment workflow. When an order is picked and packed, the system produces a packing slip that reflects the exact items and quantities being shipped — including partial shipments and backorders. Packing slips are printed alongside shipping labels, ensuring nothing is missed. With Nventory, your team spends less time on paperwork and more time getting orders out the door accurately.
