4PL vs 3PL Freight Logistics Explained

Trying to pick between 3PL vs. 4PL logistics partners? Or just want some background on both to help you build your business? We’ve got you covered. 

The accelerated shift to online working, living and shopping has had a huge impact on businesses all over the world. In Australia, we’ve seen the effects of a strained supply chain in our supermarkets, but in reality almost every business who sells products has a story to tell. 

Online sales in Australia recorded a 31.8% year-on-year growth during the 2020/21 FY, according to Australia Post. From July 2020 to July 2021, Australia’s online shopping grew almost 32%, nearly equal to the  33.2% increase of the previous fiscal year. These numbers are only continuing to rise in 2022.

For businesses selling a lot of product online, freight is the new battleground. And it’s a low-margin one. Customers expect free delivery, free returns and flexible returns windows, and the consequences of not meeting the mark are steep. 

To provide that professional shipping experience, add in some accountability and still maintain visibility over the process, many businesses look to outsource their logistics to a third-party logistics provider (3PL) or fourth-party logistics provider (4PL). 

If you’re currently weighing up 3PL vs. 4PL, it’s important that you get that decision right – picking the right freight partner is the difference between having happy customers and happy competitors.

We know it’s not an easy decision, and we work extensively with both 3PL and 4PL logistics businesses, so we’ve distilled what we know into this article. First, let’s take a look at each in some detail. 

What is 3PL logistics?

A third-party logistics partner takes over a section of your supply chain and takes responsibility for your inventory and shipping. 3PL logistics partners have their own resources and infrastructure – for example, a warehouse full of staff – which a business can outsource to if they don’t have the means or desire to do it themselves.

Your 3PL partner will often have their own relationships and rate cards with carriers, which they’ll use to send your products wherever they need to go. 

As well as storing, picking  and sending inventory, some 3PL providers can also look after customs brokering, freight forwarding, contracts and more – making them a hybrid 3PL/4PL. 

Benefits of 3PL logistics

  • No need to have your own warehouse
  • Outsourcing a large chunk of work
  • The provider takes responsibility

Challenges of 3PL logistics

  • Some carriers don’t work with brokers 
  • Your customer experience relies on picking a good partner
  • You don’t have as much control over the returns process

What is 4PL logistics?

A fourth-party or 4PL logistics provider is less about physical infrastructure and more about relationships and business strategy. 

They connect you with carriers, using their existing relationships to secure you rates that you wouldn’t otherwise have access to.

They can also look at your supply chain from a strategic perspective, as well as how it connects with the rest of the business. A good 4PL partner will suggest ways for you to align departments, tighten the belt and improve customer experience at every step.

You’d typically engage a 4PL logistics partner if your freight operation is starting to overwhelm your business (perhaps because of sudden growth), you have some bloat across your supply chain, or you’re just feeling like you’re not getting the best rates and service from your carriers. 

Benefits of 4PL logistics

  • Established relationships and buying power with carriers
  • Invoice auditing, operations and data management taken care of
  • Outsourcing a task that requires considerable resources and expertise
  • It’s like having a consultant engage with your business to drive positive change

Challenges of 4PL logistics

  • Some carriers don’t work with brokers 
  • Freight broker margins vary over time and depend on how much you’re shipping

What to consider when deciding 3PL or 4PL

There’s no black and white way to make a decision on what kind of partner to outsource your logistics to. Every business has different freight needs and business strategies. 

So while we can’t give you a straight-up recommendation, we can give you a list of the questions you need to ask yourself when choosing between 3PL vs. 4PL logistics: 

  • Is logistics a core competency of your business, or do you want it to be?
  • Do you have a warehouse (and is it staffed)?
  • Are you willing to negotiate with carriers?
  • Do you have a team to manage freight internally?
  • How much control do you want over the customer experience?
  • Are you happy with the efficiency of your supply chain?
