eCommerce fulfilment is the process of completing an order placed through an online store or marketplace. It covers everything from receiving and storing goods to processing orders, picking and packing products, dispatching parcels and managing customer returns.
Typically used by online retailers, ecommerce businesses and marketplace sellers, fulfilment can be managed in-house or outsourced to a 3PL. Many businesses choose to outsource these operations as order volumes grow, helping improve efficiency, manage stock and free up time to focus on other areas of the business.
whichwarehouse connects businesses with ecommerce fulfilment companies and 3PL providers across the UK and Ireland. Request free quotes tailored to your requirements or search by location and filter by the services you need to find a suitable fulfilment partner.
eCommerce fulfilment is one of the most in-demand logistics services in the UK and an essential part of the online supply chain. It ensures products are stored, orders are processed and purchases reach customers. As online sales continue to grow, many retailers rely on specialist fulfilment companies to manage these operations.
A typical ecommerce fulfilment operation involves receiving incoming stock, storing products within a warehouse, processing customer orders and picking and packing items ready for dispatch. Fulfilment providers also manage inventory levels, integrate with ecommerce platforms such as Shopify and Amazon, arrange courier collections and process customer returns.
Selling across multiple online stores and marketplaces means managing orders and inventory can become increasingly complex. Outsourcing to a specialist 3PL provides access to warehouse infrastructure, fulfilment technology and distribution networks without having to manage these operations independently.
eCommerce fulfilment providers offer a range of services to manage the storage, processing and delivery of online orders. These can include:
Goods-in and receiving – Receiving incoming stock, checking deliveries and booking products into warehouse inventory.
Storage and warehousing – Secure storage for products, with flexible capacity to accommodate changing stock levels.
Order processing – Receiving and processing customer orders from online stores and connected sales channels.
Pick and pack – Picking individual products, preparing orders and packaging goods ready for dispatch.
Ecommerce integrations – Connecting warehouse systems with platforms such as Shopify, WooCommerce, Amazon and online marketplaces.
Inventory management – Monitoring stock levels, tracking inventory movements and providing real-time stock visibility.
Order dispatch and distribution – Preparing parcels for collection, coordinating courier services and managing nationwide deliveries.
Returns management – Processing returned orders, inspecting products and updating inventory ready for resale.
Multi-channel fulfilment – Managing orders across ecommerce websites, online marketplaces, retail outlets and wholesale customers.
Subscription and kitting services – Assembling product bundles, subscription boxes and customised customer orders.
Technology plays an important role in modern ecommerce fulfilment, allowing online retailers to connect their sales channels directly with warehouse operations. Many fulfilment providers offer integrations with ecommerce platforms and online marketplaces, helping automate order processing, synchronise inventory and streamline dispatch.
Integrations may be available with platforms including:
Shopify – Connecting online stores with warehouse systems to automatically transfer orders and update stock levels.
WooCommerce – Integrating WordPress-based ecommerce stores with fulfilment operations and inventory management systems.
Amazon – Supporting marketplace order processing, inventory synchronisation and fulfilment requirements.
eBay – Connecting marketplace sales with warehouse inventory and order processing systems.
Through Warehouse Management Systems (WMS), providers can receive orders automatically, monitor stock levels, update dispatch information and provide greater visibility across the fulfilment process.
It's important to check which platforms they support and whether their technology is compatible with your existing systems. For more information check out our blog eCommerce Fulfilment & Warehousing: Shopify, Amazon & eBay Integration Guide.
As an ecommerce business grows, managing stock, processing orders and arranging deliveries can become increasingly demanding. Outsourcing fulfilment to a 3PL allows retailers to hand over these responsibilities to specialist warehouse operators, freeing up time and resources to concentrate on other areas of the business.
Running an in-house fulfilment operation involves costs associated with warehouse space, equipment, staffing, packaging and distribution. Outsourcing allows businesses to access existing warehouse facilities and fulfilment infrastructure without having to manage these expenses independently. This can offer a more cost-effective approach as order volumes change.
Managing daily orders, inventory and dispatch can take up considerable time, particularly for businesses experiencing increasing sales volumes. Specialist fulfilment providers have established processes, warehouse systems and dedicated teams to manage these operations, helping streamline order processing and reduce the administrative workload.
Order volumes can fluctuate throughout the year, with promotional campaigns, seasonal demand and business expansion creating additional pressure on warehouse operations. Outsourcing provides access to pallet storage and fulfilment capacity, allowing businesses to accommodate changing requirements without having to expand their own warehouse facilities.
By outsourcing the day-to-day responsibilities of warehousing and order fulfilment, businesses can dedicate more time to product development, marketing, customer service and expanding into new sales channels. Rather than managing the logistics behind every order, retailers can concentrate on developing their brand and increasing online sales.
Third-party logistics providers have experience managing warehouse operations, inventory systems, order processing and distribution. Many also offer integrations with ecommerce platforms and established courier networks, giving businesses access to specialist technology and logistics capabilities that may otherwise be difficult to manage in-house.
Choosing the right ecommerce fulfilment provider depends on your products, order volumes and operational requirements. Consider factors such as warehouse location, available storage capacity, pick and pack services, pricing structures and delivery options. It's also important to check whether a provider can integrate with your existing ecommerce platforms and marketplaces, manage customer returns and accommodate fluctuations in order volumes during busy periods.
Before committing to a fulfilment partner, compare several providers to understand what they offer and how their services align with your business. Look at their experience within your industry, service capabilities, technology and ability to support future growth. Finding a provider that meets your current requirements while offering flexibility as your business expands can help establish a reliable long-term fulfilment operation.
eCommerce fulfilment services are used by businesses selling products online that need support with storage, order processing, packing and delivery. Different types of retailers may outsource these operations depending on their order volumes, products and distribution requirements.
Businesses that commonly use ecommerce fulfilment providers include:
Online retailers – Businesses selling directly to customers through their own ecommerce websites.
Shopify and WooCommerce stores – Independent online stores looking to outsource warehousing and order processing.
Amazon and marketplace sellers – Businesses selling through Amazon, eBay and other online marketplaces.
Fashion and clothing brands – Retailers requiring product storage, individual order picking, packing and returns processing.
Subscription box businesses – Companies assembling and dispatching recurring product boxes and subscription orders.
Health and beauty brands – Businesses selling cosmetics, skincare, personal care products and beauty accessories.
Electronics retailers – Online sellers requiring organised stock management, product handling and order distribution.
Wholesale and multichannel retailers – Businesses managing both online customer orders and larger B2B or retail deliveries.
Sourcing a fulfilment provider independently can be time-consuming and complex.

An ecommerce fulfilment company manages the storage, processing, packing and delivery of orders placed through online stores and marketplaces. Many operate as third-party logistics (3PL) providers, allowing online retailers to outsource their warehouse and distribution operations.
Ecommerce fulfilment costs vary depending on storage requirements, order volumes, product sizes, picking and packing requirements and delivery services. Most providers use a combination of storage, handling, packaging and dispatch charges. Comparing quotes from multiple providers can help you find a solution suited to your budget.
Ecommerce fulfilment involves storing products in a warehouse before picking, packing and dispatching orders when customers make a purchase. Dropshipping works differently, as the retailer sells products without holding stock, with the supplier sending orders directly to customers.
A third-party logistics (3PL) provider is an external company that manages some or all of a business logistics operations. For ecommerce retailers, this typically includes warehousing, inventory management, order processing, pick and pack, dispatch and returns handling.
Many ecommerce fulfilment providers offer integrations with platforms such as Shopify, Amazon, WooCommerce and eBay. These connections allow customer orders to transfer automatically to the warehouse, while stock levels and dispatch information can be synchronised between systems. Available integrations vary by provider.
Businesses often consider outsourcing when order volumes increase, in-house storage becomes insufficient or managing daily picking, packing and dispatch takes too much time. Outsourcing can also help businesses accommodate seasonal demand and expand into additional sales channels.
Many ecommerce fulfilment providers offer returns management as part of their services. This can include receiving returned parcels, inspecting products, updating inventory and preparing suitable items for resale. The exact returns process will depend on the provider and the retailer's requirements.
Some ecommerce fulfilment providers offer international distribution, supporting businesses selling to customers outside the UK. Services may include international parcel shipping, customs documentation and coordination with overseas courier networks. Check individual provider capabilities when comparing fulfilment options.
