Outsourcing fulfillment services: Guide
8:15


Managing fulfillment in-house is a common approach for many companies. However, there comes a point when outsourcing fulfillment to a 3PL provider is a wise business decision. In fact, outsourcing can help many businesses scale efficiently, control costs and provide a better customer experience.

This guide delineates the whys, whens and hows of outsourcing fulfillment services, providing helpful information to make informed decisions about their logistics strategy. Whether you're considering outsourcing for the first time or switching providers, the information presented here will encourage clarity and help you make decisions more confidently.

The high cost of in-house fulfillment

Many businesses start with in-house fulfillment, assuming it's the most cost-effective option. However, as order volume grows, the hidden costs, inefficiencies and time demands start to add up. Outsourcing can become an increasingly attractive alternative as your internal fulfillment processes become more complex and costly over time.

Hidden costs of managing fulfillment in-house

Labor expenses: hiring, training and retaining warehouse employees.
Real estate and facility costs: leasing, maintaining and expanding warehouse space.
Time demands: time-consuming fulfillment processes that require proactive management to ensure optimal results.
Operational inefficiencies: slow processing times, lack of technology and human errors.
Growth and peak seasons: difficulty scaling operations to meet demand spikes.

Myth vs. reality: Understanding fulfillment outsourcing

There are legitimate concerns about fulfillment outsourcing, many of which center on hidden costs, contract obligations, losing control over the fulfillment process and unexpected disruptions that lead to a loss of customer trust. However, if they occur, many of these challenges can be linked directly to working with the wrong 3PL provider.

Common misconceptions about outsourcing can also dissuade businesses from considering the many benefits outsourced fulfillment can provide. Let’s separate myth from reality to provide a clearer picture.

Outsourcing fulfillment services: Myth vs. reality

Myth Reality

Outsourcing means losing control over fulfillment.

A good 3PL will provide full visibility into inventory, orders and performance. 

It’s only for large companies.

Startups and mid-sized businesses can significantly benefit from the cost savings and improved efficiency outsourcing can provide. 

3PLs are too expensive compared to in-house fulfillment.

A well-structured 3PL partnership can reduce costs by eliminating inefficiencies, providing lower shipping rates and reducing overhead expenses.

Transitioning to a new 3PL is disruptive and time-consuming.

With a structured onboarding process, brands can switch seamlessly with minimal downtime.

 

When should a business consider outsourcing fulfillment?

Generally, outsourcing fulfillment makes sense when a business can no longer properly handle its order volume. Businesses that experience fast growth will need access to additional resources, such as manpower, infrastructure and technology, to stay cost-effective and efficient. Without access to these resources, in addition to the time required to manage and oversee multiple fulfillment processes, transitioning to a 3PL provider can be the right choice.

However, deciding requires carefully evaluating costs, resources and potential drivers. Questions that can help you decide whether or not it's time to outsource fulfillment include:

  • Are your fulfillment costs rising and cutting into your profit margins?
  • Are you providing competitive fulfillment services? Or are shipping speeds inconsistent, leading to customer complaints?
  • Can your business keep up with increased order volume and demand?
  • Is scaling into new sales channels (D2C, B2B, multiple marketplaces) challenging?
  • Are your fulfillment processes slowing down business growth rather than enabling it?

When should a company change 3PL providers?

If your business is already outsourcing fulfillment services, you may need to change if your current provider falls short of expectations. Many businesses find themselves in this situation for several reasons. For example, your 3PL may be unable to scale along with increasing demand. Further, they might not meet delivery demands on time and at competitive pricing. In worst cases, you might be experiencing issues involving mismanagement of inventory, lack of visibility or even costly and unexpected fees.

If these scenarios apply to you, it's important to take the time to consider other available options and look for a 3PL company that can become a trusted and strategic business partner rather than just a service provider. Further, you'll want to transition professionally to ensure you have the support you need as you move forward to better options.

How to find the right 3PL provider

Choosing the right 3PL provider will require an effective strategy and careful consideration of your prospective 3PL service offerings and the potential benefits they can provide. Further, choosing a fulfillment partner that can align well with your business needs is important.

Consider if your 3PL can provide the following support and services:

How to find the right 3PL

Streamlined Onboarding

A structured and streamlined onboarding process that ensures a smooth transition with minimal disruptions. Look for a 3PL with a dedicated implementation team and clear onboarding timelines.

Tech-enabled omnichannel capabilities

A 3PL should seamlessly integrate with multiple sales channels (D2C, B2B, marketplaces, retail) and provide real-time inventory tracking and order management.

Nationwide network

A strategically located fulfillment network can reduce shipping costs and improve delivery speed, ensuring faster order fulfillment across regions.

Peak season and BFCM management

A reliable 3PL should have proven experience handling high-demand sales periods, such as Black Friday and Cyber Monday, with scalable solutions to manage order surges.

Flexible, transparent pricing

Pricing should be clear, predictable and scalable with no hidden fees. Look for a provider that offers customizable fulfillment plans based on your business needs.

Comprehensive services and solutions

A full-service 3PL should offer returns management, kitting, custom packaging and inventory security, providing an end-to-end fulfillment solution.

 

Make the transition

If you've concluded that outsourcing fulfillment services or switching providers is the right choice for your business, a fast and streamlined onboarding experience will be essential, especially during peak seasons. Once you understand your current fulfillment goals, you must work closely with your new 3PL to ensure a smooth transition and minimize disruptions.
