3PL Services

Independent 3PL sourcing support

What are 3PL services?

3PL services are logistics activities provided by a third party on behalf of a business. 3PL means third-party logistics, where a company outsources warehousing, stock handling, order fulfilment and transport to an external provider that runs those operations on the shipper's behalf.

Where 3PL sits in the logistics model

Understanding the different logistics party models helps businesses decide what level of support they need. A 3PL provider manages physical logistics operations, while other models involve different levels of ownership, control and coordination.

• 1PL: The first party is the business that owns the goods and manages its own logistics activities, including storage, fulfilment and transport.
• 2PL: A second party supplies a specific logistics service, such as transport or warehousing capacity, but the shipper usually manages the wider logistics operation.
• 3PL: A third-party logistics provider takes responsibility for agreed logistics functions, which may include storage, inventory control, fulfilment and distribution.
• 4PL: A fourth-party logistics arrangement is usually a broader management model where an external lead logistics provider coordinates multiple 3PL providers, systems and processes on behalf of the customer.

For many ecommerce, retail, wholesale and manufacturing businesses, a 3PL company is the practical choice when the requirement is to outsource day-to-day logistics execution. A 4PL or lead-logistics arrangement is different because the focus is on managing the wider supply chain and coordinating several logistics partners rather than directly operating one set of services.

What services do 3PL providers offer?

The scope of 3PL logistics varies between providers and depends on the needs of the customer. Some businesses require a complete outsourced operation, while others use a 3PL provider for specific functions such as storage, fulfilment or distribution.

Warehousing and storage

3PL companies provide warehouse space and operational support for holding finished goods, components or stock ready for onward movement. Services may include goods receiving, put-away, storage, stock rotation and dispatch preparation.

Inventory and stock management

A 3PL operation typically manages stock records, stock movements, cycle counts and inventory reporting. Accurate stock control helps businesses maintain visibility of available inventory and support customer order requirements.

Order fulfilment and pick and pack

Many 3PL services include ecommerce and retail fulfilment, where orders are received, picked, packed and prepared for delivery. Processes can be designed around different product types, order volumes and customer service requirements.

Transport and distribution

Transport is a key part of many 3PL logistics arrangements, covering collection, trunking, delivery and distribution services. Where transport involves operating goods vehicles, the transport operation must be run by an operator holding the correct goods vehicle operator licence. Further information is available from the UK government guidance on goods vehicle operator licences.

Returns handling and additional services

Many 3PL providers also support returns processing, including inspection, restocking and reporting. Value-added services can include labelling, kitting, product preparation and quality checks to meet specific customer requirements.

Technology and systems integration

Modern 3PL operations commonly use warehouse management systems (WMS) and connections with client platforms, including ecommerce systems, enterprise resource planning systems and order management tools. These integrations allow information to move between the business and the logistics operation.

How 3PL is priced

The cost of using a 3pl provider depends on the operation being outsourced, the space required, the activity level and the service model agreed. The following are indicative observed UK market cost structures, not a CTS quotation. Buyers can use them to sense-check proposals and understand how different 3pl companies may build their pricing.

Common cost components include storage, often charged per pallet or per square foot per week, together with goods in and goods out handling charges. Pick and pack fees are frequently structured as a charge per order plus a charge per item picked. Transport and delivery costs are usually priced separately, reflecting delivery profile, geography, service requirements and carrier arrangements. Some contracts also include account management charges and onboarding or implementation costs for setting up processes, systems and integrations.

The true cost of 3pl logistics is shaped by the detail of the operation. Order profile, storage footprint, throughput, product characteristics and seasonality all affect the final price. A headline storage rate alone rarely gives a complete view of the likely cost. Buyers should compare the full service proposal, including handling activity, technology, transport and any minimum charges or additional services.

What a 3PL contract should cover

A well-defined 3pl contract sets out what the provider will deliver, how performance will be measured and how both parties will manage changes over time. Areas normally covered include:

• Services and scope: the exact warehousing, fulfilment, transport and value-added services included within the agreement.
• SLAs and KPIs: agreed measures such as stock accuracy, despatch cut-off performance, order accuracy and on-time delivery.
• Minimum volumes or charges: any committed activity levels, storage commitments or minimum monthly fees.
• WMS and systems integration: requirements for warehouse management systems, order feeds, reporting and operational visibility.
• Peak-season handling: how the 3pl provider will manage demand spikes, promotions and seasonal volume changes.
• Stock ownership and liability: responsibilities for inventory, damage, loss, claims processes and insurance arrangements.
• Exit terms and stock transfer: notice periods, data handover, stock removal and the practical steps for moving to another operation.

How to choose and vet a 3PL provider

Selecting a 3pl provider starts with operational fit rather than simply comparing prices. An ecommerce business with thousands of small orders has different requirements from a manufacturer or wholesaler moving pallet quantities to trade customers. The right 3pl company should understand the buyer's order profile, product type and service expectations.

Key checks include warehouse location and available capacity, technology capability, real-time stock visibility and the ability to support growth and peak periods. Buyers should review financial standing, insurance arrangements, relevant accreditations and operational references. Where transport is included, the transport arm's compliance position should be checked, including the DVSA operator licence and associated requirements.

For example, a growing ecommerce brand may decide to outsource storage and pick and pack to a 3pl provider so it can handle increased demand during peak trading periods without investing in its own warehouse operation. The assessment should focus on whether the provider's processes, systems and capacity match the brand's expected volumes.

CTS provides an independent, asset-neutral procurement service for businesses looking to appoint 3pl providers. CTS owns no warehouses or vehicles and is free to shippers. Operators are checked before inclusion in a private brief, including transport operator licence position, financial standing, insurance and accreditations. CTS issues one brief to a checked shortlist, but does not rank, rate or endorse operators. Buyers compare proposals directly and make the appointment with the selected 3pl provider.
