Packing Slips: What They Are and Why They Matter

A packing slip is one of the most underrated documents in e-commerce and logistics. Placed inside the shipping box, it tells the recipient exactly what is inside—product names, SKUs, and quantities—so they can verify the order before signing off on delivery.

Packing Slip vs. Invoice

The confusion is understandable: both list items, and both are included in shipments. But an invoice is a financial request for payment with prices and totals. A packing slip is purely operational—it helps with receiving, verification, and returns processing. Many businesses send the invoice electronically and include only the packing slip in the physical box.

What to Include on a Packing Slip

  • Your company name, logo, and return address
  • Recipient name and delivery address
  • Order or reference number
  • Item list with: product name, SKU, quantity, and unit of measure
  • Carrier and tracking number
  • Box number (e.g., "Box 2 of 3") for multi-box shipments

Best Practices

Always include SKUs—they make item identification faster and reduce fulfillment errors. For orders going to retail stores or distributors, use a packing slip envelope on the outside of the box so staff can process it without opening. For international shipments, note that customs may require a commercial invoice separately from your packing slip.

Frequently Asked Questions

What is a packing slip?

A packing slip is a document included inside a shipment that lists every item in the box—their names, quantities, SKUs, and sometimes weights. Unlike a shipping label, the packing slip is for internal and customer reference and is not meant to be stuck on the outside of the package.

What is the difference between a packing slip and an invoice?

A packing slip lists items being shipped without any pricing or payment information. An invoice includes prices, totals, payment terms, and billing details. A packing slip helps the recipient verify the order; an invoice tells them what to pay and how. Many businesses include both in a shipment—packing slip inside the box, invoice attached externally.

What information should be on a packing slip?

A packing slip should include: your company name and address, the recipient name and address, order or reference number, carrier and tracking number (if available), and an itemized list with product names, SKUs, quantities, and units. Optional: product weights, dimensions, and special handling notes.

What is a SKU and why is it on a packing slip?

SKU stands for Stock Keeping Unit—a unique alphanumeric code assigned to each product variant for inventory tracking. Including SKUs on your packing slip helps the recipient verify items against their own records, and it helps warehouse staff quickly identify and process products. It is especially useful for e-commerce businesses with large catalogs.

What are the best practices for packing slips?

Print on plain white paper for readability. Place the packing slip inside the box, ideally in a clear packing slip envelope on the outside so warehouse staff can see it without opening the box. Always include SKUs for accuracy. For international shipments, include a commercial invoice separately. Keep your packing slip format consistent to build trust with repeat customers.
