Outsourcing fulfillment to a third-party logistics (3PL) partner can be a game-changer for ecommerce brands looking to scale, but success hinges on more than just picking any provider.
To truly unlock the benefits of faster shipping, lower costs, and operational efficiency, your 3PL strategy must be built on proven best practices.
In this guide, we’ll break down what sets high-performing 3PLs apart and how brands can optimize their fulfillment partnerships. From strategic inventory placement to tech integration and process automation, these best practices can help you streamline operations, improve delivery performance, and keep customers coming back.
The 3PL vs. in-house fulfillment debate
When it comes to order fulfillment, ecommerce businesses face a critical decision: should they keep logistics in-house, or partner with a third-party logistics (3PL) provider?
Both options have their advantages and challenges, and the right choice ultimately depends on your company’s unique needs, goals, and growth trajectory.
| In-house fulfillment | Outsource to a 3PL | |
| Pros | More control over fulfillment
More freedom to customize workflows |
Instant access to infrastructure, advanced technology, and industry expertise
Scalable to mid-market and beyond Economies of scale offer cost-savings |
| Cons | Requires significant upfront investment (infrastructure, technology, and staff)
Not scalable |
Less control over fulfillment
Less freedom to customize workflows |
| Costs | Rent
Utilities Equipment Labor Capital investment |
Standard pricing for storage and fulfillment services (will vary by 3PL)
Value-added services (kitting, custom packaging, etc.) |
| Best for | Small startups with with limited monthly order volume and a tight budget | Scaling brands with growing order volumes and geographically dispersed customers |
Pros and cons
Managing fulfillment in-house offers a higher degree of control over the process, allowing you to maintain brand standards and customize the experience to your exact specifications.
However, this approach also requires significant upfront investment in infrastructure, technology, and staff, as well as ongoing operational expenses.
As your business grows, you may find yourself struggling to keep pace with increasing order volumes and complexity, leading to slower turnaround times and potential customer dissatisfaction.
On the other hand, outsourcing to a 3PL company can provide instant access to a robust fulfillment network, advanced technology, and deep industry expertise, enabling you to scale quickly and efficiently.
By leveraging a 3PL’s economies of scale, you can often reduce shipping costs and improve delivery speeds, while freeing up internal resources to focus on core competencies like product development and marketing.
However, this approach also means relinquishing some control over the fulfillment process and relying on a partner to represent your brand.
Common costs
To make an informed decision, it’s essential to forecast your capacity needs and consider the hidden costs associated with each approach.
For in-house fulfillment, this means projecting order volumes and storage requirements, as well as accounting for expenses like rent, utilities, equipment, and labor. Don’t forget to factor in the opportunity cost of investing capital in fulfillment infrastructure rather than other growth initiatives.
When evaluating 3PL providers, look beyond the headline pricing and consider the full scope of services included. Some providers may charge extra for value-added services like kitting or custom packaging, while others may have minimum order requirements or long-term contracts that limit flexibility. Be sure to ask about any potential hidden fees or surcharges, such as those for receiving, storage, or account management.
Capex vs. Opex considerations
Another key factor to consider is the balance between capital expenditure (Capex) and operational expenditure (Opex). In-house fulfillment typically requires significant upfront Capex investment in facilities, equipment, and technology, which can be a barrier for cash-strapped startups or businesses with unpredictable demand. Outsourcing to a 3PL, on the other hand, allows you to convert those fixed costs into variable Opex, paying only for the services you use on a transactional basis.
This Opex model can be particularly advantageous for businesses with seasonal or fluctuating demand, as it allows you to quickly adjust capacity without the burden of idle infrastructure. However, it’s important to note that some 3PLs may require minimum order volumes or charge higher rates for lower-volume clients, so be sure to carefully evaluate pricing models and contract terms.
Choosing the right approach for your business
Ultimately, the right fulfillment approach will depend on your business’s unique characteristics and growth stage. For example, a small startup with limited order volume and a tight budget may find in-house fulfillment more cost-effective in the short term, while an established brand with a national customer base may require the scalability and reach of a 3PL partner.
In some cases, a hybrid model may offer the best of both worlds, allowing you to maintain control over certain aspects of the fulfillment process while leveraging a 3PL’s expertise and infrastructure for others. For example, you might choose to keep inventory management and quality control in-house while outsourcing pick, pack, and ship operations to a 3PL.
As your business grows and evolves, it’s important to regularly reassess your fulfillment strategy and be open to exploring new approaches. By carefully weighing the costs, benefits, and risks of each option, you can make an informed decision that supports your long-term growth and success.
7 key best practices for a successful 3PL operation
Running an efficient and scalable logistics operation requires a strategic approach that encompasses technology, cost management, communication, performance monitoring, and more. By implementing these seven key best practices, ecommerce brands can optimize their 3PL partnerships and achieve long-term success.
1. Leverage technology and automation
Technology plays a crucial role in modern 3PL operations. A robust warehouse management system (WMS) is key for maintaining inventory accuracy and providing real-time visibility into stock levels, order status, and shipping timelines.
By leveraging a WMS to power fulfillment operations, 3PLs can eliminate manual processes and streamline data flow, reducing errors, increasing throughput, and improving efficiency.
Automation technologies, such as conveyor systems, pick-to-light devices, and mobile scanning tools, can significantly enhance picking accuracy and speed.
These solutions help 3PLs optimize warehouse layouts and implement data-driven inventory placement strategies that reduce travel time and minimize shipping costs.
2. Manage costs proactively
Effective cost management is a critical component of successful 3PL operations.
Optimizing pick-and-pack processes helps 3PLs reduce labor costs and improve overall efficiency.
This may involve:
- Implementing batch picking methods, using multi-order carts, or leveraging zone picking strategies based on warehouse layout and product characteristics.
- Choosing the appropriate box sizes and materials to minimize dimensional weight charges and reduce shipping costs.
- Negotiating favorable carrier contracts based on volume can to secure discounted rates and improve profitability.
Additionally, transparent billing practices and regular invoice reviews are essential for maintaining trust between 3PLs and their clients. 3PLs should provide detailed cost breakdowns and proactively identify opportunities for optimization.
3. Prioritize communication and transparency
Clear communication and transparency are the foundation of any successful 3PL partnership. Establishing well-defined channels for information sharing between 3PLs, brands, and supply chain partners ensures that all stakeholders are aligned and informed.
To that end, your 3PL should offer:
- Proactive updates on inventory levels, order status, and shipping timelines to help set proper expectations and enable brands to make informed decisions.
- Real-time order tracking and status notifications to end customers that enhance the post-purchase experience and build brand loyalty.
- Transparent communication, detailed explanations, and timely notification when exceptions or delays occur, which is crucial for maintaining trust and finding effective solutions.
- Regular performance reviews and strategic planning sessions provide opportunities for 3PLs and brands to discuss challenges, identify improvement areas, and align on long-term goals.
4. Establish and monitor performance metrics
Measuring and monitoring key performance indicators (KPIs) ensures that 3PLs consistently meet or exceed client expectations. Critical metrics to track include order accuracy, on-time shipping, inventory accuracy, and customer satisfaction.
To maintain performance accountability and visibility into operations, your 3PL should offer:
- Detailed SLAs: Developing meaningful Service Level Agreements (SLAs) that align with business goals helps establish clear performance benchmarks and accountability. These SLAs should be regularly reviewed and adjusted as needed to reflect changing market conditions and evolving client needs.
- Data dashboards: Dashboards and reporting tools that provide real-time visibility into KPIs enable continuous monitoring and improvement. This helps both you and them identify trends and anomalies early, which the 3PL should proactively address.
- Regular business reviews: Regular business reviews that include in-depth performance analysis and action planning are essential for driving operational excellence.
5. Master advanced fulfillment workflows
As ecommerce brands expand their product offerings and explore new sales channels, 3PLs must adapt to increasingly complex fulfillment requirements.
Your 3PL should have mastery over any advanced workflows your brand requires, such as kitting and bundling, partial shipping, and backorder management.
While your brand’s needs may differ from others, some common workflows to check your 3PL can handle include:
- Kitting and bundling operations involve assembling multiple SKUs into a single package before shipping.
- Partial shipping and backorder workflows to manage out-of-stock situations and minimizing delays.
- Multi-SKU variants and complex product configurations, ideally managed via robust inventory management systems and well-defined processes.
- Quality control processes, including random inspections, barcode scanning, and weight verification, that reduce fulfillment errors and ensure that products meet brand standards.
- Specialized handling procedures and packaging materials for high-value or fragile items to prevent damage and maintain product integrity.
6. Balance brand control with 3PL expertise
Outsourcing fulfillment to a 3PL does not mean relinquishing control over your brand experience. Successful 3PL partnerships strike a balance between leveraging the provider’s operational expertise and maintaining brand identity and values.
Custom packaging and branded inserts are powerful tools for creating a memorable unboxing experience and reinforcing brand messaging. 3PLs should work closely with brands to understand their unique requirements and develop fulfillment processes that align with brand guidelines.
Documenting brand standards, including packaging specifications, insert placement, and quality control criteria, ensures that 3PL teams can consistently execute on brand vision. Regular training and communication help maintain alignment and prevent deviations from established protocols.
Collaborative problem-solving and continuous improvement initiatives allow 3PLs and brands to leverage their combined expertise to optimize the fulfillment experience. By working together to identify opportunities for enhancement, such as streamlining packaging or implementing new technologies, both parties can drive innovation and growth.
Regular quality audits and site visits provide opportunities for brands to ensure that their standards are being upheld and identify areas for improvement. When 3PLs maintain an open dialogue and work together to address any issues, stakeholders can build strong, trust-based relationships that support long-term success.
7. Develop peak season strategies
Peak seasons, such as holidays and special sales events, can put significant strain on fulfillment operations.
Developing proactive strategies to manage these high-volume periods is essential for maintaining service levels and customer satisfaction.
A 3PL’s peak season preparations should involve:
- Advanced forecasting methodologies that incorporate historical data, market trends, and promotional plans, which together help brands anticipate demand spikes and allocate resources accordingly.
- Multi-warehouse distribution strategies that help mitigate the impact of peak season surges by spreading inventory across multiple locations, which in turn reduces shipping distances and transit times.
- Staffing plans and training programs for temporary workers that makes it possible to scale operations during peak periods and quickly bring new team members up to speed to maintain productivity.
- Contingency planning for supply chain disruptions, such as weather events or carrier capacity constraints, so operations can adapt quickly to changing circumstances and minimize the impact of disruptions and maintain service continuity.
How to evaluate and select the right 3PL partner
Choosing the right 3PL partner is one of the most critical decisions you can make, as it hugely impacts the trajectory of your business.
To ensure you find the best fit for your needs, you’ll have to take a methodical, structured approach to evaluation and selection. Here is a brief guide to help you kickstart your search, and help you think through the most important considerations.
Key evaluation criteria
When assessing potential 3PL partners, there are several key factors to consider.
First and foremost, evaluate their technology capabilities. A modern 3PL should offer:
- A robust warehouse management system (WMS) that provides real-time visibility into inventory levels, order status, and shipping performance.
- Seamless integrations with your ecommerce platform and other systems to streamline operations and reduce manual work.
- A strategic network of fulfillment centers that can optimize shipping costs and delivery times for your customers.
- Scalability that can accommodate increasing order volumes and expand into new markets.
Other important evaluation criteria include the 3PL’s financial stability, pricing transparency, and industry expertise. You want a partner that not only has the resources to support your business, but also has the experiences needed to fulfill products in your brand’s category.
Essential questions to ask potential 3PLs
To thoroughly vet potential 3PL partners, come prepared with a list of essential questions covering key areas such as operations, technology, pricing, and support.
For example, you could ask a potential partner:
- What is your process for receiving and storing inventory?
- What safeguards do you have in place for quality control?
- How do you approach peak season, and what steps do you take to ensure you can fulfill spikes in order volume on time?
- What is your technology stack like?
- What integrations do you offer (i.e., Amazon, Walmart Marketplaces, Shopify, ecommerce tools, etc.)? Are they direct integrations?
- What is your timeline for onboarding customers?
- What is your pricing structure? Can you provide detailed, monthly invoices and guarantee no hidden fees or surprise line items?
Be on the lookout for red flags in their responses, such as vague answers or an unwillingness to provide references. A reputable 3PL will be transparent about their capabilities and limitations and will work with you to find solutions that fit your needs.
Understanding 3PL pricing models and contracts
3PL pricing can be complex, with various models and potential hidden costs. Common pricing structures include per-order, per-pick, and storage-based fees.
To avoid surprises, it’s essential to understand what’s included in each model and ask about any additional charges, such as setup fees, account management fees, or long-term storage fees.
When reviewing contracts, pay close attention to the length of the agreement and any flexibility provisions. You’ll want the ability to adjust your terms as your business needs change. Clear termination clauses and data ownership provisions are also critical to protect your interests.
Don’t hesitate to negotiate for fair and transparent pricing. A good 3PL partner will be open to finding a mutually beneficial agreement that supports your business’s growth and success.
