3PL or 4PL: where should responsibility sit?
A 3PL typically executes freight, warehousing or distribution. A 4PL coordinates a wider provider network and operating picture. The right model depends on how many parties, milestones and decisions the client needs one lead to control.
- Use 3PL for defined execution scope
- Use 4PL for multi-provider coordination
- Define escalation and reporting before launch
