A 3PL (third-party logistics) runs logistics operations for you: transport, warehousing, distribution, with own or subcontracted assets. A 4PL (fourth-party logistics) does not execute: it orchestrates, managing your 3PLs and carriers as a single integrator, typically without assets. The practical difference is who touches the cargo and who touches the information. The question nobody asks before signing: when you outsource execution, who audits the executor?
- runs processes
- 3PL
- orchestrates executors

The 1PL–4PL ladder
1PL y 4PL ladder
Who touches the cargo vs who touches the information.
1PL
Own fleet
2PL
Point-to-point carrier
3PL
Runs full processes
4PL
Orchestrates executors
Healthy rule: whoever runs or administers spend should not be who audits it.
When each model fits
3PL when execution is not your edge and volume does not justify assets. 4PL when you manage so many executors that coordination is the problem. In both, whoever administers spend must not be judge and party of the audit.

What OCL runs
OCL Cargo is a shipper-side autonomous TMS: agents with computer use build the trip file and reconcile before pay, whether the invoice is from a direct carrier or a 3PL. It can stamp invoice and Carta Porte. Coexists without day-one migration; humans on exceptions. 5–7% pattern when auditing 100%.

Key takeaways5 points
- 3PL executes; 4PL orchestrates. The question is who audits.
- MX mid-market often fits 3PL; 4PL when coordination itself is the problem.
- Risks: subcontract opacity, opaque bundled cost, evidence you do not own.
- Healthy rule: the executor does not audit.
- OCL audits carrier or 3PL invoices the same; 5–7%; 6–8 week pilot.

Frequently asked questions
Managed transport: 8–15% margin over carriers, or bundled rate. Warehousing: by position, move, or mix.
It replaces coordination, not judgment. Someone on your side sets rules, measures service, and audits spend.
It is a 3PL specialized in international freight. On forwarders we measure 5–7% spend gaps.
Whoever runs or administers spend should not be who audits it.
No: you outsource execution and keep control with your own agents that audit the 3PL invoice like any carrier.
