Packing slips play a crucial role in the order fulfillment process, serving as a detailed record of items included in a shipment. This guide provides a comprehensive overview of packing slips, why they’re essential for businesses and customers alike, and how to set them up effectively. Whether you’re managing a small eCommerce shop or a large-scale warehouse, understanding how to use packing slips can streamline operations and reduce shipping errors.
What is Packing Slip?
A packing slip, also known as a packing list or delivery docket, is a crucial document in logistics that accompanies a shipment of goods. It provides a detailed summary of the items included in a delivery, ensuring accuracy and transparency between the shipper, carrier, and recipient. Unlike an invoice, a packing slip typically does not include pricing information—it focuses purely on what is being shipped.
Packing slips are vital in order fulfillment, helping warehouse teams verify that all ordered items are picked, packed, and shipped correctly. For the consignee, they serve as a checklist to cross-reference the delivered goods against the original purchase order. In larger supply chains, packing slips assist with inventory reconciliation and return processing and serve as proof of shipment discrepancies or damages.
Purpose of a Packing Slip
Shipment integrity
A packing slip acts as a physical verification document used during the picking, packing, and dispatching stages of order fulfillment. Warehouse personnel rely on the packing slip to ensure that the contents of a shipment align with the purchase order or sales invoice. Also, the packing slip minimizes discrepancies and reduces the risk of errors during transit by providing a clear breakdown of SKU numbers, quantities, and product descriptions.
Ability to divide orders
Packing slips also facilitate the division of orders across multiple shipments, which is especially valuable in logistics operations involving split shipments or backorders. When inventory is spread across various distribution centers or when certain items are temporarily out of stock, businesses may need to fulfill a single customer order in parts. A well-prepared packing slip for each parcel helps clarify what items are included in each shipment and which are pending.
This is crucial for inventory management systems and order tracking. Segmenting the order while maintaining transparency reduces customer confusion and enhances supply chain efficiency. Additionally, the packing slip helps customer service teams handle inquiries more effectively by referencing which items were dispatched and when.
Customer satisfaction
When customers receive a detailed packing slip alongside their shipment, they gain confidence in the transaction. It provides a tangible confirmation of what was ordered versus what was delivered, thereby reducing the likelihood of claims or returns due to misunderstandings.
Key Information on a Packing Slip
For businesses engaged in inventory management and order processing, understanding the key elements of a packing slip is essential to maintaining operational efficiency and customer satisfaction.
Shipping information
Shipping information is one of the most critical sections on a packing slip. It includes details such as the recipient’s name, full delivery address, shipping method (e.g., ground, express, air freight), and the shipping date.
This data ensures the package is routed correctly and delivered within the expected timeframe. This section is frequently cross-referenced in logistics workflows with the shipping label and the carrier’s tracking system to monitor delivery status and resolve transit issues efficiently.
List of items
The list of items section provides a detailed breakdown of all products included in the shipment. Each line item typically consists of the product name, SKU (stock keeping unit), quantity shipped, and occasionally the unit price or product description.
This allows warehouse teams to confirm accuracy during packing and receiving, and helps the recipient verify that the correct items have been delivered. Including this list also aids in dispute resolution in case of discrepancies between what was ordered and what was received.
Missing items
This section prevents confusion for the customer and provides an audit trail for follow-up logistics actions. Clear labeling such as “To be shipped separately” or “Out of stock – shipping later” is often used. Including this information ensures the recipient does not mistakenly report missing items as lost or incorrectly fulfilled.
Inventory number
An inventory number is a unique identifier that businesses assign to individual products within their inventory management system. This number helps shippers and recipients track and verify items accurately on a packing slip. Standard formats include Stock Keeping Units (SKUs) and Universal Product Codes (UPCs), which are frequently used to streamline warehouse operations.
In practice, inventory numbers are essential for locating products in a storage facility and are often tied to inventory software for quick access. If an issue arises, such as a missing or damaged item, the customer can refer to the inventory number on the packing slip, allowing the seller to trace and resolve the problem swiftly. This system improves inventory accuracy, enhances order traceability, and supports efficient customer service.
Slip number
The slip number is a unique code assigned to a packing slip, helping businesses track and manage individual shipments, especially when an order is split across multiple packages. This identifier links each package to the same customer order, ensuring all items are correctly grouped during shipping and delivery.
For example, if a single order is divided into several boxes, each box will include a packing slip with the same slip number. This helps logistics staff and recipients verify that all parts of the order belong together. The slip number also plays a key role in internal systems such as warehouse or order management software, supporting accurate tracking, smoother communication, and quicker resolution of shipping-related issues.

The differences between packing slips and invoices, shipping labels, delivery notes?
Four commonly used documents: packing slips, invoices, shipping labels, and delivery notes, serve distinct purposes. Understanding their differences is crucial for warehouse staff, shippers, and customers alike to avoid confusion, ensure compliance, and maintain operational accuracy.
Below is a comparison table that highlights the key distinctions among these documents:
| Feature | Packing Slip | Invoice | Shipping Label | Delivery Note (often Proof of Delivery – POD) |
| Primary Purpose | To itemize the physical contents of a specific package or pallet for verification by the recipient. | A commercial document issued by a seller to a buyer, requesting payment for goods sold or services provided. | To provide all necessary information for a carrier to transport a shipment from its origin to its destination. | To provide evidence that a consignment was delivered to the intended recipient and confirm the state of the goods. |
| Key Information Included | A detailed list of items within the shipment (SKUs, descriptions, quantities shipped), and the order number. Typically, this list excludes pricing. | Itemized list of goods/services, unit prices, total amount due, payment terms, tax details, invoice number, consignor and consignee financial details. | The information includes the addresses of the consignor (shipper) and Consignee (recipient), the tracking number, carrier information/service type, barcodes for sortation, and often weight/dimensions. | List of goods delivered, quantities, date and time of delivery, name and signature of the recipient, any remarks on damage or shortages. |
| Who Primarily Uses It? | Recipient (for checking received goods against the order), Warehouse staff (for picking and packing accuracy). | Buyer’s Accounts Payable department (for payment), Seller’s Accounts Receivable department (for collections), and Customs (for international shipments). | Carrier personnel (drivers, sorters), automated sortation systems, dispatch teams, and recipients (for tracking status) are also needed. | Consignee (to acknowledge receipt), Carrier (as Proof of Delivery), Consignor (for delivery confirmation and dispute resolution). |
| When Is It Generated/Used? | Generated during order fulfillment; typically included inside the package with the goods. Used by the recipient upon delivery. | Generated after an order is placed or goods are shipped; often sent separately (email/post) to the buyer. Used for payment processing and accounting. | Generated when the shipment is prepared for dispatch by the carrier; affixed securely to the package’s exterior. Used throughout the transit process. | It often travels with the goods or is presented by the carrier at the point of delivery. It is signed by the recipient, and a copy is retained by the carrier and returned to the shipper. |
| Contains Financial Data (Pricing)? | No | Yes (its primary function involves financial details) | No | No (typically, its focus is on acknowledgment of receipt, not value) |
