Third Party Logistics (3PL): Complete Guide to Outsourcing Logistics, Fulfillment, Warehousing, and Transportation

By Raymond

What Is Third Party Logistics (3PL)?

Third Party Logistics (3PL) is the outsourcing of logistics operations to a specialized external provider that manages some or all aspects of warehousing, inventory management, order fulfillment, transportation, shipping, returns processing, and supply chain operations on behalf of a business. A 3PL allows companies to focus on sales, marketing, product development, and customer experience while logistics experts handle inventory storage and order delivery. The Council of Supply Chain Management Professionals (CSCMP) defines third-party logistics as the use of external companies to perform logistics functions that have traditionally been performed internally.

In practical terms, when a customer places an order on a Shopify store, Amazon marketplace, or ecommerce website, a 3PL receives the order data, picks the product from warehouse inventory, packs it, ships it to the customer, and often handles returns as well.

For growing ecommerce brands, DTC companies, wholesalers, subscription businesses, and international sellers, a 3PL provides the infrastructure, technology, warehouse space, and logistics expertise needed to scale efficiently.

What Does 3PL Mean?

Definition

3PL = Third Party Logistics Provider

The three parties involved are:

1. Manufacturer or Brand

2. Customer

3. Logistics Partner (3PL)

Instead of owning warehouses, hiring warehouse staff, negotiating carrier contracts, and managing fulfillment operations internally, businesses outsource these activities to a third-party specialist.

How Does a 3PL Work?

Step-by-Step Process

Step 1: Inventory Is Received

The business sends inventory to the 3PL warehouse.

The 3PL:

· Receives stock

· Verifies quantities

· Registers inventory

· Assigns storage locations

Step 2: Inventory Is Stored

Products are stored in warehouse locations and tracked through inventory management systems.

Typical tracking includes:

· SKU management

· Batch tracking

· Serial numbers

· Stock levels

· Warehouse locations

Step 3: Customer Places an Order

An order is received through:

· Shopify

· WooCommerce

· Amazon

· Magento

· BigCommerce

· Custom ecommerce platforms

The order automatically transfers to the 3PL system.

Step 4: Pick and Pack

Warehouse staff or automation systems:

· Locate products

· Pick inventory

· Verify order accuracy

· Prepare packaging

Step 5: Shipping

The 3PL selects the carrier and shipping service.

Examples:

· DHL

· UPS

· DPD

· FedEx

· PostNL

Tracking information is returned automatically to the customer.

Step 6: Returns Management

Many 3PL providers also manage:

· Customer returns

· Product inspections

· Restocking

· Refund workflows

3PL vs In-House Logistics

What’s the Difference?

Factor	In-House Logistics	3PL
Warehouse Ownership	Required	Not required
Warehouse Staff	Managed internally	Managed by provider
Technology Investment	High	Included
Scalability	Limited	Flexible
Geographic Expansion	Difficult	Easier
Fixed Costs	High	Lower upfront costs
Logistics Expertise	Internal responsibility	Outsourced expertise

When In-House Logistics Makes Sense

Businesses may keep logistics internal if:

· Order volume is low

· Products require unique handling

· Existing warehouse investments are significant

· Full operational control is essential

When a 3PL Makes Sense

Businesses often benefit from outsourcing when:

· Orders are growing rapidly

· International expansion is planned

· Warehouse costs are increasing

· Customer delivery expectations are rising

3PL vs 4PL

What Is a 4PL?

A Fourth Party Logistics (4PL) provider manages an entire supply chain, including multiple logistics providers.

Comparison

Feature	3PL	4PL
Warehousing	Yes	Often outsourced
Fulfillment	Yes	Managed through partners
Transportation	Yes	Oversees network
Strategic Supply Chain Management	Limited	Extensive
Multiple Provider Coordination	Limited	Core responsibility

A 3PL executes logistics operations, while a 4PL primarily manages and coordinates the overall logistics ecosystem.

Potential Risks of Outsourcing Logistics

Provider Dependency

Changing providers can require:

Service Variability

Not all providers offer the same level of:

This is why provider selection is critical.

Signs You Should Outsource Logistics

You Experience Frequent Shipping Delays

Delayed orders often indicate fulfillment capacity issues.

Inventory Management Is Consuming Too Much Time

If internal teams spend more time managing warehouse operations than growing the business, outsourcing may be beneficial.

Storage Costs Continue to Increase

Warehouse leases, staff, equipment, and utilities can become significant fixed costs.

International Customers Are Growing

Cross-border fulfillment becomes increasingly complex as brands expand into new countries.

You Need Faster Delivery

Local inventory placement often reduces shipping distance and transit times.
