What is eCommerce fulfillment?
eCommerce fulfillment is the end-to-end process that turns an online order into a delivered (or returned) product, which is no doubt the strategic revenue and retention lever for B2B leaders transforming retail and omnichannel commerce.
This part of the supply chain includes operations like storage, inventory management, order management, packing, shipping, returns, post order tracking, etc.
Shipments, returns, inventory, warehousing, and omnichannel routing must be treated as integrated tech services (OMS, WMS, PIM, CRM + carrier APIs) to deliver predictable cost, speed, and CX at scale, making it the backbone of modern retail operations.
It can be said that even before you understood the concept of fulfillment, it has always been an integral part of your business from the beginning.
Why eCommerce fulfillment matter for business leaders?
Statista shows that 60% of retailers now outsource at least part of their fulfillment, with 20% fully relying on 3PL partners, demonstrating a global shift toward tech-enabled, automated operations.
For C-level executives, this means fulfillment is no longer optional but core to:
- Strengthening digital trust, with consistent, accurate, on-time delivery.
- Unlocking scalability, especially during peak seasons or international expansion.
- Enhancing margins, by optimizing inventory, routing, and warehouse efficiency.
- Building a unified commerce ecosystem, where online and offline data flows in real time.
With rising complexity in order volumes, SKUs, and omnichannel journeys, leaders must ensure their fulfillment systems are integrated, automated, and data-driven.
Key steps in eCommerce fulfillment
Modern eCommerce fulfillment includes multiple interconnected operations that determine delivery speed, accuracy, and customer experience, which is a critical lever for operational efficiency, cost savings, and scalability.
1. Warehousing
Warehousing is the first aspect of order fulfillment that stores inventory in an organized fashion for better accessibility. Specifically, according to ShipBob, it is known as the process of storing physical goods or inventory in a warehouse or storage facility before they are sold or distributed, and most of them are very high-volume and fast paced places with product being moved constantly.
Warehouses safely and securely store items is the key factor influencing locating the products easily and quickly, and maintaining a track of your inventory in a better convenient manner. As eCommerce grows, warehouses have shifted toward tech-driven, high-velocity environments.
Core functions of modern warehousing:
- Real-time inventory visibility (WMS): Reduces stockouts and improves demand planning.
- Optimized storage layouts: Faster pick paths and higher order accuracy.
- Secure, monitored storage: Minimizes shrinkage and misplacements.
- Automation-ready design: Supports AMRs, conveyors, and robotic picking systems.
2025 insight: Automation is accelerating
According to MHI Industry Report 2024, despite earlier market concerns, warehouse automation is now scaling faster than expected:
- Global automation adoption increased by 40% over the last two years.
- Robotics adoption is projected to increase from 41% to 83% over the next five years.
- Inventory optimization tech is expected to rise from 58% to 92%.
For instance, according to DHL’s news release, DHL has invested $1.17B in automation and uses 7,500+ robots, with 90% of warehouses deploying at least one automation or digital technology.
2. Inventory Management
The next crucial operation included in eCommerce fulfillment is inventory management, which is the monitoring of an eCommerce business’s stocked goods including storing inventory, ordering and restocking inventory, and inventory forecasting to assess customer demands and forecast in advance for your business.
Not only does correctly managing inventory imply proactively reordering the right inventory quantity for stockouts and backorders prevention, but also, it can be a source of leverage for eCommerce companies looking to increase efficiency and reduce operational costs. Rachel Andrea Go explained that with the right configuration, it will allow businesses to better manage their cash flow, predict and plan for sales velocity, and ensure a seamless buyer experience.

For instance, retailers using AI-driven forecasting have achieved up to 30% reduction in overstocking and 20% fewer stockouts (McKinsey 2024). This directly impacts profitability and customer satisfaction.
3. Order Management
Order management is the command center for tracking and processing all orders across multiple sales channels. It connects eCommerce platforms, warehouses, payment systems, and customer service tools.
What an effective order management system (OMS) provides:
- Unified view of all orders across website, marketplaces, POS, and social commerce.
- Automatic routing to the nearest or most efficient fulfillment location.
- Instant syncing with WMS and inventory systems.
- Real-time status tracking for customers and internal teams.
C-level impact:
A connected OMS reduces manual intervention by up to 80%, cuts fulfillment time, and enables omnichannel models like BOPIS, ship-from-store, or curbside pickup.
4. Pick and Pack Fulfillment
The picking and packing process will proceed after an order is received in the eCommerce fulfillment. It refers to using a picking list to retrieve items from storage as soon as an order is placed online, and packing is the act of putting all ordered stuff in a box or poly mailer together with any necessary packing materials. Picking and packaging require complete accuracy and precision so that no inaccurate order is packed and delivered to the customer.
Why pick & pack matters:
- Speed: Automated picking can improve efficiency by 2–3x.
- Accuracy: Reduces wrong-item shipments that hurt brand trust.
- Cost efficiency: Less manual handling = lower labor cost.
- Customer satisfaction: Proper packaging reduces returns due to damage.
5. Shipping
Shipping is the final-mile execution that decides whether customers return to your brand. It includes label creation, carrier selection, dispatching orders, and handling delivery tracking.
Three key shipping factors to optimize:
- Shipping costs: Dynamic rate shopping can reduce costs by 10–20%.
- Packaging options: Right-sized packaging lowers shipping fees & damage.
- Real-time tracking: Essential for customer transparency and fewer support tickets.
6. Returns Management
Returns in eCommerce fulfillment involves receiving, assessing, and processing returned items into the available stock. ShipBob showed that 92% of customers state they will buy something from an online store again if returns are easy, which demonstrates how eCommerce returns policy plays a vital role in customer experience improvement and the importance of ease of return to eCommerce shoppers as it can be a key factor influencing your sales.
Besides, by having optimized returns management, it can lead to better profit margins by reducing transportation spend, to reselling items that would have been a complete loss if disposed of upon return. Furthermore, by offering options to your customers who wish to return items that make it easier for them, it can go a long way to boost customer satisfaction. Lastly, returns management can help you identify ways to reuse, resell or recycle materials.
What modern returns management includes:
- Automated return labels.
- Integration with OMS for instant refund updates.
- Reverse logistics routing rules.
- Options like drop-off, in-store return, courier pickup.
- Recycle/refurbish/resell workflows.

1. In-house fulfillment
In-house fulfillment (self-fulfillment) is the DIY approach where merchants store, pack, and ship orders themselves. It works for small brands with low order volume, but it becomes unsustainable as demand grows due to increased labor and storage requirements.
- Pros:
- No outsourcing or third-party storage fees
- Full control over packaging and product quality
- Ideal for early-stage businesses with limited orders or tight cash flow
- Cons:
- Difficult to scale as volume increases
- Time-consuming and resource-heavy
- Lacks professional logistics expertise and bulk-shipping discounts.
2. Third-party logistics (3PL)
3PL fulfillment is a model that allows you to outsource or hand over the management of your distribution infrastructure to a specialized logistics company that will handle your entire eCommerce fulfillment flow within its own fulfillment center.
- Pros:
- Faster, more efficient order processing.
- Easily scale with higher-order volume.
- Access to logistics expertise and new sales channels.
- Cons:
- Less control over packaging and the final delivery experience.
3. Dropshipping
Dropshipping lets you sell products without holding inventory. When a customer orders, the supplier ships directly to them. This reduces upfront costs and helps test new markets, but offers less control over fulfillment, inventory, and branding. Profit margins per sale are also lower.
- Pros:
- Low startup investment required.
- Easy to test new markets and products.
- No need for storage or handling inventory.
- Cons:
- Limited control over inventory and fulfillment
- Product quality and customization may suffer
- Lower profit margins per sale
