History

The term 4PL is generally considered to have been introduced by Audric Adger, which registered it as a trademark

 described the 4PL as an "integrator that assembles the resources, capabilities, and technology of its own organization and other organizations to design, supply chain solutions".

The trademark was later abandoned, and the term has become a part of the public domain.

Definition

A fourth-party logistics provider is an independent, singularly accountable, non-asset based integrator of a client's supply and demand chains.

Confusion

Nowadays advisors, consultants, software companies and even 3PLs lay claim to being a 4PL. This is because any company advising a customer on logistics, transportation, and supply chain matters feels it may somehow claim to be a 4PL. This is effectively the case only when the principle of neutrality is respected, and that any conflict of interest is avoided.

A fourth-party logistics provider must also offer services considering a 360 degree view, which is not focused on its ability to implement the recommendations it gives, but on all the options available in the market.

Principle of neutrality

 company, otherwise it would lead to conflict of interest.

It has been sometimes argued that a 4PL is the same thing as a "non-asset based 3PL". This is not the case. Considering that probably 90% of the world's 3PL are "non-asset based", they nevertheless generate revenues & profits from their "non-asset based" activities. As such a 3PL cannot be a 4PL in the same time, as this would lead to conflict of interest. Indeed it would then have a tendency to recommend to customers its "non-asset based" operation as the best possible option.

Examples of 4PL
