Why would a company using a 3PL switch to a 4PL?
I've been thinking about how logistics needs evolve as businesses grow.
A lot of companies seem to do well with a 3PL for warehousing and fulfillment, but at some point some of them decide to move to a 4PL model instead.
For those who've been through it—or worked with clients who have—what was the main reason for making the switch?
Was it because of:
- Managing multiple 3PL providers?
- Better transportation optimization?
- Supply chain visibility?
- Cost reduction?
- International expansion?
- Something else?
At what point does a 4PL start providing enough value to justify the additional complexity (and cost)?
I'd love to hear real-world experiences from people who've made the transition or decided to stay with a 3PL.
