When an order arrives, the recipient needs a simple way to confirm that the package contains exactly what was expected.
That is where a packing slip comes in.
A packing slip is part of the wider fulfillment process and helps connect the information behind an order with the physical products inside a shipment.
The process typically looks like this:
Order → Picking → Packing → Packing Slip → Shipping → Receiving
For ecommerce businesses, retailers, wholesalers, and manufacturers, packing slips can help improve order accuracy, simplify receiving, and make it easier to resolve fulfillment issues.
In this guide, we explain the packing slip meaning, what information it contains, what a packing slip looks like, and how it differs from documents such as invoices, shipping labels, and Bills of Lading.
What Is a Packing Slip?
A packing slip is a document that lists the items included in a shipment.
It typically contains information such as:
- Product descriptions
- SKUs
- Quantities
- Order numbers
- Recipient details
- Shipment information
The purpose of a packing slip is to help the sender and recipient verify that the correct products and quantities have been included in the order.
The exact format can differ between businesses, industries, and types of shipments.
In fulfillment operations, a packing slip forms part of the documentation that connects warehouse picking and packing activities with the final shipment.
What Is a Packing Slip Used For?
Packing slips can support several important warehouse and receiving processes.
Verifying Package Contents
The recipient can compare the products inside the package with the items listed on the packing slip.
This makes it easier to identify:
- Missing products
- Incorrect quantities
- Wrong items
- Partial shipments
Improving Packing Accuracy
Warehouse teams may use packing information during final order checks before a shipment leaves the fulfillment center.
This supports quality control and helps reduce fulfillment errors.
Identifying Orders
Packing slips often contain information that connects the physical shipment with the customer’s order.
This may include:
- Order number
- Purchase order number
- Customer information
- Shipment reference
For B2B orders, this information can be particularly useful during receiving and reconciliation.
Handling Partial Shipments
A customer may place one large order that is shipped in multiple packages.
A packing slip can show exactly which products are included in each individual shipment.
This helps both the sender and recipient keep track of outstanding items.
Supporting Returns and Customer Service
Packing documentation can also help identify products when a customer needs to return an item or contact customer service.
Order numbers, SKUs, and product descriptions make it easier to trace the original shipment.
What Information Is Included on a Packing Slip?
The exact contents vary, but a packing slip commonly contains the following information:
| Information | Purpose |
| Order number | Identifies the customer order |
| PO number | Connects the shipment to a purchase order where applicable |
| SKU or item number | Identifies individual products |
| Product description | Clarifies what is included |
| Quantity | Shows how manu units were shipped |
| Shipper information | Identifies the sender |
| Recipent information | Idenitifies the intended recipient |
| Shipment details | Provides relevant shipment information |
| Special notes | Communicates order-specific instructions |
A packing slip does not necessarily include prices.
This is one of the key differences between a packing slip and an invoice.
Packing Slip Example
A simple packing slip might look like this:
Order: GL10245
Shipment date: September 3
Customer: Example Retail BV
Shipping address: Example Street 10, Amsterdam
| SKU | Product | Ordered | Shipped |
| TSH-BLK-M | Black T-Shirt – Medium | 2 | 2 |
| CAP-GRN | Green Cap | 1 | 1 |
| BOT-750 | 750 ml Bottle | 3 | 3 |
This packing slip example allows the recipient to quickly confirm that all requested products and quantities are present.
In practice, businesses may also include additional references, barcodes, return information, or internal warehouse details.
What Does a Packing Slip Look Like?
A packing slip usually looks like a simple order summary.
It commonly includes:
- Company name or logo
- Order number
- Recipient information
- Shipping address
- Product SKUs
- Product descriptions
- Quantities
- Shipment references
The design can range from a basic warehouse document to a branded customer-facing insert.
The most important requirement is that the information is clear enough to identify the shipment and verify its contents.
Packing Slip vs Invoice
Packing slips and invoices may contain some of the same order information, but they serve different purposes.
| Packing Slip | Invoice |
| Describes shipment contents | Requests or records payment |
| Used mainly for fulfillment and receiving | Used mainly for billing and accounting |
| Usally accompanies or relates to a shipment | May be sent separately |
| Often lists SKUs and quantities | Typically includes prices, totals, taxes, and payment details |
A packing slip helps answer: What is inside this shipment?
An invoice helps answer: What is being charged?
The two documents should therefore not be treated as interchangeable.
Packing Slip vs Shipping Label
A packing slip and shipping label also serve completely different functions. A packing slip tells you what is supposed to be inside the shipment. A shipping label tells the carrier where and how the package should be transported.
A shipping label commonly contains:
- Sender address
- Recipient address
- Tracking number
- Barcode
- Carrier information
- Shipping service
If a shipping label is incorrect, the package may be sent to the wrong destination. If a packing slip is incorrect, the recipient may receive misleading information about what should be inside the order.
Packing Slip vs Bill of Lading
A packing slip primarily identifies the contents of an order or package.
A Bill of Lading (BOL) is a transportation document used in freight shipping and serves a broader legal and operational role between parties such as:
- Shipper
- Carrier
- Consignee
A Bill of Lading contains important transportation information about the goods being moved.
Although both documents describe products, they are used for different purposes and should not be confused.
Packing Slip vs Packing List
The terms packing slip and packing list are often used interchangeably, particularly in everyday fulfillment operations.
However, the exact terminology and format can depend on the business and shipping context.
In international freight, a packing list may be more detailed and form part of the wider set of import and export documentation.
It may include information such as:
- Number of packages
- Weights
- Dimensions
- Product descriptions
- Package references
For standard ecommerce fulfillment, packing slip is often the more familiar term.
How Packing Slips Fit Into the Order Fulfillment Process
Packing slips are most useful when viewed as part of a complete fulfillment workflow.
1. Customer Places an Order
An order is created through an ecommerce platform, sales system, or Order Management System (OMS).
2. Order Reaches the Warehouse
The order information is transferred to the warehouse or fulfillment center.
A Warehouse Management System (WMS) helps determine where the required products are stored.
3. Products Are Picked
Warehouse staff locate the correct SKUs and quantities.
Barcode scanning can be used to verify that the right products are selected.
4. Products Are Packed and Verified
The picked products move to the packing station.
The order can then be checked for:
- Correct SKUs
- Correct quantities
- Packaging quality
- Special instructions
5. Packing Documentation Is Generated
The packing slip or related documentation is created using order information such as:
- Order number
- SKU
- Product description
- Quantity
6. Shipping Label Is Created
The shipping label is generated using the recipient’s delivery information and selected carrier service.
This usually includes a tracking number.
7. Shipment Leaves the Warehouse
The shipment is handed over to the carrier and enters the transportation network for final delivery.
This shows how packing slips connect order management, warehouse operations, shipping, and receiving.
Are Packing Slips Required?
Not every shipment requires a physical packing slip.
Whether one is included depends on:
- Business processes
- Customer requirements
- Type of shipment
- Industry
- Receiving procedures
- Applicable documentation requirements
Some ecommerce businesses increasingly use paperless fulfillment processes.
These may include:
- Digital order confirmations
- Electronic invoices
- Paperless returns
- Electronic warehouse records
B2B orders, however, may rely more heavily on packing documentation to support receiving and purchase-order reconciliation.
Do Ecommerce Orders Need Packing Slips?
Ecommerce businesses do not always need to include a physical packing slip in every parcel.
However, packing slips can still provide value by supporting:
- Order verification
- Returns processing
- Gift orders
- Customer service
- Customer experience
Some brands may also use the document as a branded insert.
Others choose paperless fulfillment to reduce unnecessary packaging materials and simplify the customer experience.
The right approach depends on the product, customer expectations, and fulfillment process.
How Packing Slips Help Prevent Fulfillment Errors
Packing slips can support an important final verification step before orders leave the warehouse.
The relationship is:
Packing Slip → Order Verification → Correct SKU & Quantity → Order Accuracy → Customer Satisfaction
Common fulfillment mistakes include:
- Wrong SKU
- Missing item
- Incorrect quantity
- Mixed-up customer orders
Accurate order data, barcode scanning, and quality control processes can help identify these issues before shipping.
For businesses processing large order volumes, combining packing documentation with warehouse technology can significantly improve fulfillment consistency.

Packing Slips Support Accurate Order Fulfillment
A packing slip is a document that lists the products included in a shipment and helps the sender and recipient verify the order.
Although it may seem like a simple document, it plays a useful role within the wider fulfillment process by connecting order information with the physical products being packed and shipped.
Clear packing documentation can support receiving, customer service, returns, and order verification while helping businesses reduce fulfillment errors.
When combined with accurate inventory management, warehouse technology, and reliable fulfillment processes, packing slips contribute to more efficient logistics operations and a better customer experience.
