Ecommerce 3PL Explained: A Complete Guide for Growing Your Online Business
Last Updated: July 11, 2025 | ⏱ 7 min
If you’re running an online store and starting to feel overwhelmed by shipping, packing, and keeping track of inventory, you’re not alone. As your business grows, handling logistics on your own can get stressful fast. Maybe your garage is overflowing with boxes, you're spending hours printing labels, or you’re constantly making last-minute trips to the post office. It’s exciting to see orders coming in, but keeping up can quickly turn chaotic.
Many brands solve this by partnering with a 3PL for eCommerce fulfillment. With the right eCommerce fulfillment partner, you can save time, simplify operations, and keep your customers happy while you focus on growing your brand. Let’s explore what a 3PL means for eCommerce, and how you can utilize it to grow your online business.
What is a 3PL in eCommerce
A 3PL in eCommerce is a third-party partner that takes over essential logistics functions for online stores, including inventory storage, order fulfillment, shipping, and returns management.
By outsourcing to a 3PL, eCommerce businesses can offload the heavy lifting, such as warehousing products, picking and packing orders, coordinating shipments, and handling returns. This hands-off approach reduces operational complexity and overhead, allowing merchants to focus on growing their brand while the logistics are handled by experts.
Instead of worrying about storage and shipping logistics, you can focus on growing your business while your 3PL ensures products reach your customers quickly, accurately, and professionally.
Why You Should Consider 3PL eCommerce Fulfillment Services
While businesses of all kinds can benefit from working with a 3PL, eCommerce brands specifically face unique challenges due to rapidly shifting demands and consumer expectations. Just 30 years ago, a business’s sales were often limited to the number of people who could physically walk into their store. Today, thanks to eCommerce, you can sell globally in a matter of seconds.
That global reach unlocks tremendous growth potential, but if your fulfillment strategy can’t keep up, the opportunity can quickly turn disastrous. Without the right infrastructure, growth can become overwhelming.
One day, you're launching a new product. The next, your garage is a makeshift warehouse, your living room is a maze of cardboard, and you’re sprinting to the post office with 200 packages.
Where’s the time to enjoy your success?
The limitless growth of eCommerce can become a bottleneck when you're managing everything on your own or with a small team. At that point, you’re faced with a choice:
Lease your own warehouse space, hire a team, and invest in technology
Or partner with a 3PL and let them handle it for you
How 3PL Can Grow Your eCommerce Business
Deciding to outsource your warehouse operations to a third-party logistics (3PL) partner often comes at a pivotal moment in your business journey. There are a few key indicators that suggest it might be time to make the shift:
Are peak order volumes pulling resources away from other critical departments?
Have you turned down sales opportunities because your team can’t keep up with fulfillment?
Is your current physical space limiting your ability to scale?
While each 3PL provider offers unique capabilities, most deliver a foundational suite of services, —including warehousing and end-to-end order fulfillment. A strategic partnership with the right 3PL can unlock long-term growth opportunities and operational efficiencies you might no expect:
Scalable Warehousing
As your online orders grow, so does your need for space. A 3PL gives you flexible warehousing that scales with your business without the burden of long leases you may not always need. Whether you're shipping a few dozen packages or hundreds each day, your 3PL keeps operations smooth and responsive.
You can scale up or down as needed without worrying about wasted overhead or unnecessary expenses.
Cost Savings
Because many 3PLs manage fulfillment for multiple eCommerce businesses, they negotiate volume discounts on shipping, packaging, and warehouse labor. The best part? These savings are often shared with you.
Coast to Coast Fulfillment, for example, partners with multiple carriers to offer the most cost-effective and efficient shipping solutions for every order. And since you're not investing in warehouse space, staffing, or costly software, your overhead stays low while your capabilities increase.
Expanding Your Reach
Your brand may have a global reach, but the physical location of your fulfillment center plays a critical role in your success. That’s why many 3PLs choose strategic locations near major cities, ports, and interstate highways. It allows them to receive inbound shipments efficiently and deliver outbound orders faster.
For example, Coast to Coast Fulfillment is strategically located in the Northeast Corridor of the United States, a region allowing one-day shipping to over 60 million people. Access to faster delivery times and competitive shipping rates not only reduces operational costs but also drives more sales and boosts customer satisfaction.
Kitting and Assembly
Beyond shipping and storage, many 3PLs also offer kitting and assembly services. This means they take multiple individual items or components and combine them into one packaged set.
This can include support for customized packaging, assembling retail display units and following specific shipping guidelines, such as precise placement of labels and barcodes.
Coast to Coast Fulfillment also offers reverse logistics services. If items are returned, we can inspect them, re-kit as needed, and restock, so your inventory is accurate and ready for resale.

Step 2: Onboarding & Set Up
Once you decide to move forward, we begin the onboarding process. We’ll send you an Onboarding Form that gathers all the essential information needed to create your account in our Warehouse Management System (WMS). This includes your company details, SKU list, and any reporting preferences, like who should receive regular updates on shipping, postage, or EDI activity.
You’ll also receive our Welcome Packet. This document outlines our processes and procedures, so you’ll know exactly what to expect. It also introduces you to your dedicated Account Manager, who will be your primary point of contact going forward. We’ll guide you through setting up any necessary integrations, such as connecting your eCommerce platform or configuring EDI systems. You’ll also get access to our client portal, known as Data Depot, where you can track inventory, view orders, and monitor reporting in real time.
Step 3: Inventory Transfer
Once your CTCF account is set up and we’ve integrated with your webstore, it's time to ship your inventory to our facility. As soon as your products arrive, our warehouse team gets to work. We process your goods into inventory within 24 to 72 hours of arrival, which can be viewed at any time via our online portal. If your eCommerce platform is Shopify, CTCF will even take care of updating inventory levels for you.
Step 4: Go Live & Optimize
With your inventory received and your systems connected, you’re officially live with Coast to Coast Fulfillment. From here on out, orders placed through your online store will automatically flow into our system, where our experienced team picks, packs, and ships each one with care. This ensures your customers enjoy a seamless experience from the moment they click “buy” to the moment their package arrives.
