3PL: Third-party logistics in Procurement and sourcing
November 19, 2025
Third-party logistics (3PL) refers to the outsourcing of logistics services to specialized external providers. In the procurement context, 3PL allows companies to focus on their core competencies while professional logistics service providers take over transportation, warehousing and distribution. Find out below what exactly 3PL means, how it is managed and what strategic advantages it offers.
Key Facts
- 3PL includes transportation, warehousing, order picking and distribution services by external providers
- Cost reduction of 10-25% through economies of scale and specialization of logistics service providers
- Flexibility for seasonal fluctuations without own capacity investments
- Focus on core business by outsourcing complex logistics processes
- Global reach through established networks of 3PL providers

Definition and meaning of 3PL?
Third-party logistics describes the strategic decision to transfer logistics functions to external service providers.
Core elements of 3PL
3PL service providers take on various logistical tasks along the supply chain. These include goods receipt, quality control, storage and palletizing as well as distribution to end customers.
- Transport management and route optimization
- Warehousing and inventory management
- Picking and packing
- Returns processing and quality assurance
3PL vs. 4PL
While 3PL provides operational logistics services, 4PL acts as a strategic integrator. 4PL providers coordinate several 3PL partners and take over the entire supply chain management.
Importance of 3PL in Procurement
For purchasing organizations, 3PL allows them to concentrate on strategic procurement activities. Outsourcing logistics processes reduces complexity and creates transparency regarding delivery conditions and cost structures.
Process, control and planning
The successful implementation of 3PL requires structured planning and control processes.
Provider selection and contract design
Suitable 3PL partners are selected on the basis of defined criteria such as service quality, geographical coverage and technical capabilities. Contracts regulate service level agreements (SLAs), liability issues and key performance indicators.
- Request for Proposal (RFP) with detailed requirements
- Evaluation of references and certifications
- Definition of KPIs and reporting standards
Operational control and monitoring
Ongoing control is achieved through regular performance reviews and continuous monitoring. Delivery performance and cost development are systematically monitored and corrected in the event of deviations.
Integration into the supply chain
3PL services must be seamlessly integrated into existing procurement processes. This includes the connection to ERP systems, pre-shipment notifications and coordination with suppliers.
Tacto Intelligence
Combines deep procurement knowledge with the most powerful AI agents for strong Procurement.
Operational KPIs for 3PL
3PL performance is measured using defined key figures that evaluate operational excellence and cost efficiency.
Service level and quality indicators
On-time delivery rate, picking error rate and damage rate measure service quality. Perfect Order Rate combines several quality dimensions into one overall key figure.
- Delivery reliability (OTIF - On Time In Full): >95%
- Picking accuracy: >99.5%
- Schadensrate: <0,1% des Warenwerts
Cost ratios and efficiency
Cost per shipment, storage costs per unit and transport costs per kilometer evaluate cost efficiency. These key figures enable benchmarking and continuous optimization.
Flexibility and responsiveness
Lead time variability and capacity utilization measure the adaptability of the 3PL partner. Schedule flexibility and scalability are crucial for coping with fluctuations in demand.
Risks, dependencies and countermeasures
The outsourcing of logistics functions entails specific risks that must be minimized through appropriate measures.
Loss of control and dependencies
The transfer of logistical responsibility can lead to reduced control over processes and quality. Strong dependencies on the 3PL partner increase the risk of failure and make it more difficult to switch providers.
- Regular audits and quality controls
- Diversification through several 3PL partners
- Detailed SLAs with penalty clauses
Data protection and information security
Sharing sensitive business data with 3PL partners requires robust security measures. Data breaches can lead to legal consequences and reputational damage.
Cost risks and hidden fees
Incomplete cost calculations can lead to unexpected additional costs. Freight surcharges, demurrage and additional services must be agreed transparently in order to avoid budget overruns.

Practical example
A medium-sized mechanical engineering company outsources its spare parts logistics to a 3PL provider. The service provider takes over the storage, picking and worldwide shipping of over 15,000 spare parts. Specialized warehouse technology and optimized processes reduce logistics costs by 20%, while the delivery time for emergency parts is reduced from 48 to 24 hours.
- Centralization of five decentralized warehouses in one hub
- Implementation of a warehouse management system
- 24/7 availability for critical spare parts
Current developments and effects
The 3PL market is subject to continuous change due to technological innovations and changing customer requirements.
Digitization and automation
Artificial intelligence and machine learning optimize route planning, inventory management and demand forecasts. Automated warehouse systems and robotics increase efficiency and accuracy in order picking.
- Predictive analytics for demand planning
- IoT-based shipment tracking
- Blockchain for transparency in the supply chain
Sustainability and green logistics
Environmental aspects are becoming increasingly important. 3PL providers are investing in electric vehicle fleets, optimized route planning to reduce CO2 and sustainable packaging solutions.
E-commerce and same-day delivery
Growing online retail requires flexible fulfillment solutions. 3PL providers are developing specialized services for cross-docking and last-mile delivery to meet rising customer expectations.
Conclusion
3PL enables companies to strategically focus on core competencies while simultaneously professionalizing their logistics processes. Successful 3PL partnerships require careful provider selection, clear contract design and continuous performance management. Digitalization opens up new opportunities for increasing efficiency and transparency in the supply chain.
FAQ
What distinguishes 3PL from independent logistics?
3PL transfers logistical responsibility to specialized service providers, while all processes are handled internally with independent logistics. 3PL offers cost benefits through economies of scale, but requires the development of control competencies and harbors dependency risks.
What are the costs for 3PL services?
3PL costs are made up of basic fees, variable costs per shipment, storage costs and additional services. Typical cost structures include handling fees, transportation costs and IT system connection. A transparent cost calculation is essential for budget planning.
How is 3PL integrated into existing systems?
System integration takes place via standardized interfaces such as EDI or APIs. ERP systems are connected to the warehouse management systems of the 3PL provider. Master data synchronization, stock synchronization and automated messages ensure smooth processes.
What contract models are available at 3PL?
Common models are transaction-based billing, flat-rate contracts or gain-sharing approaches. The contract term varies between one and five years. Service level agreements define performance standards, while flexibility clauses allow adjustments to be made in the event of changing requirements.
