Learn what 3PL services can include, how warehouse and transportation roles differ, and what to define in an outsourcing agreement.
A 3PL performs logistics work for another business
A third-party logistics provider (3PL) performs one or more logistics functions for a customer under an agreed service scope. Examples include warehousing, fulfillment, transportation coordination, and related administration. C.H. Robinson’s overview describes services ranging from individual logistics functions to broader combinations. The term is commercial: it does not by itself tell you who owns a facility, controls inventory, contracts with carriers, or handles a claim.
What can a 3PL do?
Store and fulfill orders
A warehouse-focused provider may receive goods, store inventory, replenish locations, pick and pack orders, and hand shipments to carriers. For e-commerce, the work may also include order imports, packaging, returns, and status updates. Define the sites, shifts, products, order cutoffs, and customer flows you need. Ask who approves inventory adjustments and how the provider reports a short, damaged, or misrouted order.
Coordinate transportation
A 3PL may help plan moves, select carriers, tender shipments, monitor delivery, or review freight invoices. Ask whether it acts as an advisor, administers your process, or arranges transportation through carriers. The federal broker definition focuses on compensated arranging of property transportation by an authorized motor carrier (49 CFR §371.2). If that activity is part of the service, identify the entity doing it and the corresponding responsibilities.
Combine services
Some contracts bundle storage, fulfillment, returns, and transportation; others limit the provider to one function. Bundling may reduce handoffs, but it also makes it important to know which team owns each decision, data record, and exception. List what the provider performs, what it subcontracts, and what remains with your staff.
When should you consider outsourcing?
A company may consider a 3PL when it needs a new facility or delivery capability, wants to outsource a defined operating task, faces seasonal demand, or needs help coordinating a lane or order workflow. Compare outsourcing with the current process using the same scope: sites, labor, inventory, carrier costs, systems, service expectations, and transition work. A proposal should make clear what is included in the fee and what triggers an additional charge.
How to evaluate a provider
Give each candidate a representative receiving and order scenario. Test a receipt, inventory adjustment, changed order, delayed pickup, damaged item, invoice question, and data export. Review facility and lane coverage for the exact operation, written service measures, staffing assumptions, insurance and liability terms, audit rights, data access, and exit assistance. Define who may authorize substitutions or additional charges. If a provider offers savings or accuracy claims, ask for the baseline, calculation, period, exclusions, and remedy.
FAQ
Is a 3PL a federal license?
No. It is a broad commercial term. Specific activities may have separate regulatory requirements; 49 CFR §371.2, for example, defines a property broker by activity.
Does a 3PL own the goods?
Not necessarily. Inventory ownership, custody, risk, and recordkeeping depend on the contracts and transaction. State these responsibilities explicitly.
How does a 3PL differ from a carrier?
A carrier transports freight. A 3PL may arrange transport, operate a warehouse, or coordinate other logistics services; identify the actual party performing each task.

3PL Services buying guidance
At a glance: “Third-party logistics provider” (3PL) is a broad commercial label for an outside provider performing one or more contracted logistics functions, such as transportation, warehousing, fulfillment, or coordination. It is not, by itself, a single federal operating authority, proof of asset ownership, or an allocation of every supply-chain duty. Evaluate the actual statement of work and legal activities. If a provider arranges for-hire motor transportation for compensation, the federal broker definition may be relevant.

Common workflows
- Specify an outsourced warehouse or fulfillment operation: Write the operating scope around receiving, storage, inventory control, picking, packing, shipping, returns if included, locations, labor responsibilities, system interfaces, and service measurement. Compare shared and dedicated proposals by capacity commitments, transition, cost drivers, data access, and exit terms; provider labels do not establish facility availability or operational fit. What is a Third Party Logistics Provider (3PL)?
- Separate transport brokerage from other 3PL services: For each transportation task, identify the contracting party, actual carrier, who tenders or arranges the movement, compensation, and the service record. Federal regulation defines a broker by the activity of arranging or offering to arrange transportation by an authorized motor carrier for compensation, not by the provider's broad “3PL” label. 49 CFR § 371.2 — Definitions; 49 U.S.C. § 13102 — Definitions
- Test inventory and order data across systems: Use a real order and receipt to test identifiers, inventory adjustments, picking status, shipment confirmation, and exception ownership. Ask which system is the system of record, how errors and duplicate events are corrected, what data can be exported, and who approves changes to operating rules.

Questions to ask providers
- Which operations are included, at which sites, shifts, modes, commodities, and volumes, and what is expressly out of scope?
- Who provides labor, facilities, equipment, inventory control, transport decisions, and customer-service escalation?
- If the provider arranges motor-carrier freight for compensation, what entity contracts and what broker authority or regulatory duties apply?
- How are service levels, inventory accuracy, orders, shipments, exceptions, exclusions, and remedies measured in the contract?
- What integrations, data ownership, access controls, retention, export, and termination assistance are included?
- What are the transition tasks, minimums, capacity commitments, variable charges, surcharges, and exit costs in the written proposal?
- Can the provider demonstrate an inbound receipt, inventory adjustment, order fulfillment, freight exception, and reconciled invoice using our process?
Frequently asked questions
Is “3PL” a specific federal license?
No single federal authority is established by the commercial label alone. The actual activity may trigger separate rules; for example, federal regulations define a motor freight broker by arranging transportation for compensation. 49 CFR § 371.2 — Definitions; 49 U.S.C. § 13102 — Definitions
Does a 3PL always own warehouses or trucks?
No. A 3PL can provide selected functions under different arrangements; whether it owns or operates facilities or equipment must be confirmed in the provider's specific scope and contract. What is a Third Party Logistics Provider (3PL)?
How is a 3PL different from a freight broker?
The terms describe different things: 3PL is a broad service-market label, while federal broker rules define a transportation activity. A provider can offer multiple logistics services; classify the actual activity and entity rather than inferring legal role from its brand. What is a Third Party Logistics Provider (3PL)?; 49 CFR § 371.2 — Definitions
How do I compare shared and dedicated warehouse proposals?
Compare the exact sites, reserved capacity, labor and equipment scope, service measures, transition, cost basis, data access, and exit clauses in each written proposal. Neither label guarantees cost or suitability. What is a Third Party Logistics Provider (3PL)?
Should a 3PL contract promise savings or service improvements?
Only use measurable commitments whose baseline, denominator, exclusions, data source, and remedies are defined in the contract. Provider-level benefit statements are not evidence of the buyer's likely outcome. What is a Third Party Logistics Provider (3PL)?
What should a 3PL technology demonstration cover?
Test a receipt, inventory change, order release, fulfillment, shipment confirmation, error correction, and data export. Confirm which platform is the record source and which party resolves missing or conflicting data. What is a Third Party Logistics Provider (3PL)?
