Introduction
The biggest challenge for eCommerce businesses is not attracting customers; instead, it’s getting orders to arrive on time. Miss that, and trust goes out the window. Third-party logistics (3PL) providers are now an important part of this process, offering specialized solutions that simplify fulfillment. Because of this, the demand for 3PL services continues to climb.
In reality, the industry itself is expanding rapidly. According to IBISWorld, there were 69,703 3PL companies in the US in 2024, which is a 0.9% increase from the previous year. And this growth shows no signs of slowing down. In fact, the 3PL market is expected to reach $1.78 trillion by 2030. And it is growing at a CAGR of 5.48% between 2025 and 2030.
While several factors contribute to this rise, the boom in eCommerce is the core factor.
Growth is great, but it also creates challenges. For 3PLs, focusing on eCommerce fulfillment is one of the biggest challenges. Here are some of the most common challenges 3PL warehouses run into and the practices that help manage them better.
What Is 3PL eCommerce Fulfillment?
3PL eCommerce fulfillment refers to outsourcing logistics tasks, like warehousing, inventory management, order processing, shipping, and returns to a specialized service partner.
Working with a 3PL enables online retailers to do what they do best: grow their business. Meanwhile, logistics experts handle complicated stuff like shipping, warehousing, and inventory management.
Key Challenges in 3PL eCommerce Fulfillment
Actually, smooth 3PL warehouse management is critical for operational efficiency, visibility, and customer satisfaction. But similar to any fast-moving industry, it comes with challenges. Alright, here are some common 3PL challenges and ways to address them:
1. Integration Complexities
Both 3PLs and eCommerce brands lean on multiple technologies to run operations. These systems must integrate well for data to flow correctly. So even a small syncing glitch can cause lost or corrupted data, which disrupts the entire supply chain.
Solution:
Implement an advanced Warehouse Management System (WMS) such as Mantis LVS, which enables seamless integration and real-time data synchronization across platforms. This helps reduce manual processes, eliminate duplication, and maintain operational accuracy.
2. Limited Inventory Visibility
Keeping track of SKUs across multiple sales channels is no small task. Real-time inventory tracking helps make sure you have enough stock on hand to fill orders and avoid missed sales. But as product lines and channels grow, visibility becomes difficult.
Solution:
Use a WMS that provides real-time inventory visibility. At Rubicon Logistics Solutions, our advanced WMS Mantis LVS integration offers complete transparency across the supply chain, helping businesses forecast accurately and optimize inventory levels across all fulfillment centers.
3. Scalability Challenges
Demand in eCommerce is rarely steady. Seasonal peaks, flash sales, and viral trends can all create sudden order surges. Without scalable systems, 3PLs risk delayed orders and poor customer experiences.
Solution:
Choose flexible logistics solutions that can scale up or down based on demand fluctuations. Mantis LVS allows logistics providers to expand capacity effortlessly, maintaining speed and accuracy during high-volume periods.
4. Shipping and Delivery Delays
Basically, picking and packing are only part of the fulfillment story. The real test comes when products need to quickly move from warehouses to doorsteps. Therefore, any delay in this last-mile stage can cause missed delivery deadlines, damage reputations, and increase costly returns.
Solution:
Work with 3PL and WMS providers that maintain strong carrier networks. Mantis LVS integrates with nearly 20 major carriers, enabling faster parcel management and delivery tracking. With these integrations, eCommerce businesses can minimize delays and improve customer satisfaction.
5. Inefficient Returns Management
eCommerce businesses inevitably encounter returns, and poor management of them can quickly drain profits. Without a clear plan, returns become slow, expensive, and frustrating for customers.
Solution:
Adopt a robust reverse logistics process. Mantis LVS helps identify returned items, track them against original orders, and direct them to the right destination, whether restocking, resale, or disposal. This level of visibility transforms returns into revenue recovery opportunities.
Best Practices for Building an Effective 3PL eCommerce Fulfillment Strategy
To overcome fulfillment challenges and strengthen operations, 3PL providers and eCommerce businesses should focus on the following best practices:
1. Finding the Right 3PL Partner
If you’re a retailer expanding online or a DTC brand, you will benefit from partnering with an expert 3PL provider. Evaluate potential 3PL providers based on their capabilities, tech integrations, and experience in eCommerce fulfillment.
Start by figuring out your priorities: the musts, the nice-to-haves, and the dealbreakers. Sort your list before you start looking, so you don’t waste time on 3PL partners that aren’t right for you.
2. Prioritize Integration and Communication
System integration between your business and the 3PL is the backbone of eCommerce fulfillment. Because of this, make sure every new tool or technology works with your existing setup before purchasing it.
Clear communication is just as important. If a potential partner struggles to keep you updated during the evaluation stage, that’s a red flag for future collaboration.
3. Utilize Advanced WMS Technology
Always work with 3PLs that use an advanced WMS like Mantis LVS. These systems support inventory tracking, enhance supply chain visibility, order processing, and reporting. Show businesses where things might go wrong so they can fix them.
4. Optimize Packaging and Shipping Processes
Efficient picking, packing, and shipping minimize both time and money. Find 3PLs that use WMS with warehouse automation technologies like RFID, voice picking, pick-to-light, automated material handling systems, etc. These tools speed things up and, at the same time, cut down on errors.
Besides, aligning with carriers for competitive shipping rates means shipments get there when they should, and customers stay satisfied.
5. Establish a Returns Management Strategy
Modern shopping behaviors, such as bracketing (ordering multiple sizes or colors) and wardrobing (buying, wearing, and returning items) mean returns happen anytime. What’s important is building a strategy that handles them efficiently.
Partner with a fulfillment center that is good at reverse logistics. Besides, a strong returns process can turn potential losses into resale opportunities, while also increasing customer trust.
6. Monitor and Improve Performance Regularly
To be honest, you can’t improve what you don’t measure. Tracking Key Performance Indicators (KPIs) like order accuracy, inventory levels, and customer satisfaction helps you identify areas for improvement. Continuous performance monitoring helps your fulfillment meet what customers expect.
How to Select the Right 3PL Partner
Selecting the right 3PL provider is a crucial step in building a successful eCommerce fulfillment strategy. Alright, consider these factors when evaluating your options:
- Experience in eCommerce fulfillment: Choose an eCommerce fulfillment partner with a solid history in online retail. That’s because an experienced partner will already understand the challenges of fast shipping, precise order handling, and efficient returns.
- System compatibility: Your 3PL’s technology should integrate well with your current eCommerce platform and supporting software. Be sure to ask for a demonstration during their tech stack evaluation process.
- Scalability: As your business grows or faces seasonal demand spikes, your partner should be able to expand operations without disruption. So discuss how they manage busy periods and whether they have the resources to scale.
- Service Level Agreements (SLAs): Look closely at the provider’s SLAs and KPIs, such as delivery accuracy, processing speed, and customer satisfaction. In fact, these metrics will give you a realistic view of their reliability.
- Reputation and references: Research their reputation in the eCommerce space. Read testimonials, request references, and look into any awards and recognition they have received. You can trust them if they have a positive track record.
