Advantages and disadvantages of a 3PL
6:18


For growing companies, outsourcing logistics to a 3PL can ensure resilience, scalability, efficiency, cost control and customer satisfaction. Whether you need your 3PL to handle inventory management, warehousing, fulfillment, packing and shipping, outsourcing these internal processes to an expert can optimize them and help you focus on core business activities.

However, outsourcing also comes with risks and challenges; the benefits or drawbacks will depend on the provider you decide to work with. In this blog, we'll explore the advantages and disadvantages of 3PL services and provide some helpful guidance on when outsourcing logistics could be the right choice for your business.

Potential advantages and disadvantages of 3PL services

There are benefits and drawbacks to consider when outsourcing fulfillment, so the decision to outsource logistics isn’t clear-cut for all companies. In fact, the disadvantages might outweigh the advantages in certain cases, complicating the decision even further. Below, we’ve compared some of the top factors a business should consider. 

Advantages & disadvantages of 3PL services

  Advantages Disadvantages
Scalability Rapid scaling up or down as needed May require long-term contracts that can be restrictive
Cost savings Negotiated shipping rates can help reduce costs. Outsourcing costs can potentially outweigh savings
Technology Access to proprietary warehouse WMS/real-time tracking/ analytics Potential integration challenges with legacy systems
Geographic reach Nationwide or global fulfillment can reduce shipping time Limited storage controls can lead to delays
Business support Enables your business to focus back on core business activities. Removes a level of direct control over fulfillment processes.
Expertise Access to logistics professionals and corresponding network Not all 3PLs provide the same level of service

When the disadvantages outweigh the advantages

While outsourcing to a 3PL can provide several benefits, it's not the right choice for every business. Businesses that lack stability in order volume, have highly specialized needs or require complete control over their fulfillment operations might find certain challenges and disadvantages outweigh the benefits of outsourcing.

For example, startups with low order volumes may find outsourcing costs too high. Further, companies that offer highly customized, fragile or highly regulated products might face unexpected challenges if their 3PL can not support those unique requirements.

If a company is heavily invested in its own logistics infrastructure, switching to a 3PL might not provide enough cost savings to justify the move. Ultimately, the decision to outsource boils down to whether or not a 3PL provider can optimize the efficiency of your business's internal processes.

Is it time for you to outsource fulfillment logistics to a 3PL?

There are clear signs that indicate when it might be a good time to outsource to a 3PL provider. Below, we’ve listed some of the top challenges companies face when handling fulfillment in-house and suggest when it might be time to outsource some or all of your logistics operations. 

When you should consider outsourcing logistics to a 3PL provider

Challenge

Description

When to act

Struggling with order volume Excesses in order volume that lead to delays and bottlenecks in production Once you recognize damages to the customer experience via reviews
Inconsistent shipping times Packages arriving late or not at all due to inconsistent shipping methods If you have >5% of orders ship late (or >1/10 in smaller operations)
Limited storage space Running out of storage space or needing to rent additional space is costly If you have >85% warehouse utilization rate
High shipping costs Bottom-line costs affecting the overall operations If you are losing customers at checkout or avoid selling to certain regions due to cost
Fulfillment errors Incorrect items, quantities or missing items in an order If you have an order accuracy rate <99%
Managing returns Returns becoming a bottleneck due to lack of staff or poor optimization If returns take longer than 3-5 business days to process
Omnichannel fulfillment Errors stemming from differing customer experiences by marketing channel If 20-30% of orders come from multiple channels
