Order Fulfilment: Meaning and Strategies

March 2025


In this article, we cover everything you need to know about the meaning of order fulfilment so that you can make an informed, educated decision as to whether your eCommerce fulfilment should be outsourced, managed in-house, or requires a hybrid fulfilment setup.

What Is Order Fulfilment in Supply Chain Management?

Order fulfilment refers to the entire process that starts when a customer places an order and ends when the product is delivered to the customer. It involves storing the goods and managing inventoryprocessingpicking and packagingshipping, and handling returns.

For eCommerce companies, efficient order fulfilment is vital as it ensures timely delivery, enhances customer satisfaction and strengthens brand loyalty.

How Is Order Fulfilment Shipping Different from Shipping?

Shipping is just one part of the broader order fulfilment process. While shipping describes transporting the product, order fulfilment starts when the order is placed and ends when it reaches the end customer.

Order Fulfilment Strategies

There are four distinct types of order fulfilment, which relate to which party, or parties, carry out the storage and distribution.

  • In-house order fulfilment

With in-house order fulfilment, the retailer's employees handle fulfilment on their premises but may still work with a delivery management company to access discounted shipping rates.

This format can be ideal for merchants who manage their inventory in-house and want total end-to-end control over the entire operation. As the business grows and more storage space is required, they may want to migrate to outsourcing or a hybrid order fulfilment model.

  • Outsourced order fulfilment

Outsourcing order fulfilment to a third-party logistics (3PL) company is less capital-intensive than investing in one's own premises. Some businesses outsource their operations, including customer service, storage, reworking, and returns, with varying degrees of involvement. Learn more in our guide to third-party logistics.

A retailer usually outsources one of these elements in the early stages to implement other solutions as their business needs evolve. This creates more time for your workforce to focus on marketing, product development and other ways to grow the business.

  • Hybrid Fulfilment

Some retailers need to retain production in-house for bespoke and rarely sold items. The fulfilment house may lack the expertise to handle such work, so the retailer could adopt a hybrid fulfilment model in which the 3PL handles their fast-moving goods. This allows the retailer to better focus on tailored customer orders. Other retailers may adopt a hybrid model to de-risk their expansion.

  • Dropshipping

Partnering with a drop shipper is a much more hands-off approach to order fulfilment. With this method, your products are sourced from a supplier and advertised through your eCommerce site. When a customer places an order, it is sent to your drop-ship partner, who will fulfil it on your behalf. 

While typically less profitable than handling and selling your products, drop shipping is an increasingly popular fulfilment method that enables retailers to expand their product range to fill gaps in their market. Drop shipping involves minimal risk for the retailer and is best suited to startups and retailers testing new suppliers without committing capital. No money is tied up with inventory, warehousing or other overheads.

On the other hand, retailers have less control over this order fulfilment process and entrust their reputation to the drop shipper. Should there be an issue with a product or the service, customers will assume the fault lies with the retailer. Product supply is similarly out of your control, so if something goes out of stock, it can take a while to restock.

Order Fulfilment Process: How Does Order Fulfilment Work?

To show the order fulfilment process in action, we have broken down each stage in detail and outlined some of the key benefits your eCommerce business can achieve when you partner with Whistl:

1. Goods in

We receive the goods from suppliers or directly from the manufacturer. Goods are then checked into our inventory management system according to the related manifest; upon arrival, we confirm receipt, unload, inspect, scan, and sort the items before placing them in the warehouse.

  • Goods are made available for order as quickly as possible, with a benchmark of four hours after arrival.
  • Fulfil any range of products with any level of detail (we can scan barcodes/serial numbers/add relevant barcodes if required). RFT technologies are used for fast and accurate scanning
  • Quality checking procedures can be added for all or specific suppliers (we offer quality checks/measurements/weight verification/photography)
  • Avoid storage fees by pre-selling and benefiting from our flexible cross-dock solution.

2. Warehousing

Goods are stored in safe, modern warehouses nationwide. 

  • You can scale and grow without constraints and not worry about peak periods.
  • Space is allocated in the most cost-efficient way to ensure consistent order picking.
  • All products with expiry dates are managed using the FIFO (First In, First Out) method, with batches and dates accurately captured.
  • Make data-driven inventory decisions and avoid stockouts with our reporting system (provides progress reports/exceptions/outstanding order details).
  • Your goods are kept safe, tidy, and stored under the right conditions.

​​​Benefits of Order Fulfilment

If you choose to outsource to a fulfilment specialist, your business can enjoy a range of fantastic benefits. 

  • Fulfilment services can save time

Working with a specialist, dedicated fulfilment house lets you leverage their experience and expertise. The most significant time-saving benefits come from implementing tailored picking methods, such as zone, batch, discrete, or wave picking.

Furthermore, working with a fulfilment outsourcer means they will have experienced staff ready to carry out all other elements, including receiving, reworking, labelling, returns, and even repacking.

  • Save money

A fulfilment centre like Whistl is sufficiently large to give you access to collaborative buying power. Your online store will be one of hundreds or thousands of other businesses utilising the shared eCommerce warehouse.

Our national fulfilment centre locations allow companies such as Ethical Superstore to access discounted shipping rates based on the collective volume of their shipments, as well as customised packaging solutions to minimise their required storage space. This, in turn, saves the retailer money and leaves more room for further growth.

  • Optimise processes

Whilst you may outsource your fulfilment, you will still need to run some key elements of your business in-house. This includes processing orders via an order/warehouse management system (OMS/WMS), as well as sales channels and marketplaces such as eBay, Amazon, and OnBuy.

One of the key advantages is that an effective company will assess your technical infrastructure and, in some instances, consult on better technology to help optimise your business from your side. An outsourced company like Whistl will help you:

  • Hit dispatch targets with auto-fulfilment of new orders
  • Get real-time financial reporting with automatic invoicing
  • Group customers for marketing using auto-tagging
  • Set triggers to order new items from your suppliers to minimise understocking
  • Gauge predicted demand from marketplace analytics and sales volumes to minimise overstocking
  • Achieve better overall visibility of your inventory management
  • Improve your brand image

Effective inventory management and streamlined fulfilment processes mean you can give your customers a consistently positive experience, meet your customer expectations, and maximise the likelihood of positive reviews.

Poor reviews posted to your site can be damaging, potentially costing future sales. Most importantly, it’s a sign that something isn’t working as it should, and the causes should be investigated to try to rectify the problem.

Partnering with a fulfilment centre with robust carrier relationships and proactive delivery-tracking support means you can offer online shoppers the best delivery options from the start and minimise the risk of deliveries failing.

At Whistl, we also offer outsourced contact centre services to complement our fulfilment offering, ensuring there is always someone to address your customers’ queries.

  • Expand your business reach

An internationally focused fulfilment centre will give you access to new markets, customs compliance resources and, in some cases, overseas ‘in-country’ warehouses so that you can minimise your exposure to customs charges, store goods close to overseas online shoppers and mirror the performance of your international competitors.

Some providers are integrated with or optimised to meet the stringent requirements to trade on emerging international marketplaces, such as:

  • Mercado Libre in Latin America
  • Taobao in China
  • Jumia in Africa
  • Access more space and get your inventory under control.

If there is no product location identification or structure in your current warehouse, your business may lack space. However, a fulfilment warehouse must operate efficiently not only to ensure customers receive their orders on time but also to ensure goods arrive on time and in an organised, efficient manner. Remember, a failure to receive goods efficiently can cost sales.

At Whistl, we ship over 20 million tracked parcels and over 3.8 billion items annually, including mail, packets, and untracked parcels. We boast a network of fulfilment houses totalling 1 million square feet, demonstrating we’re more than capable of housing your stock and meeting your needs.

Challenges of the Order Fulfilment Process

When managing fulfilment in-house, you must train your staff on the various picking methods to ensure efficient use of time. Getting fulfilment wrong can break your business. Some common challenges within the order fulfilment process include:

Inventory control: Ensuring accurate inventory records is a consistent challenge, especially because inaccurate data can lead to overstocking or product shortages, with associated costs.

Technology: The proper infrastructure is critical to ensure you can receive, handle, pack and deliver goods that exceed your customers’ expectations. Businesses that do not invest in advancing technology and integrations risk falling behind in order fulfilment processes. Leverage seamless order processing, inventory management, and shipping software to create and maintain positive customer experiences.

Order accuracy: Order accuracy, coupled with speed, is integral in the picking and packing process – but it also requires balance to get right. This is critical, as receiving the wrong order, poorly packed goods, or delayed deliveries can lead to consumer dissatisfaction.

Challenges can still occur when outsourcing or adopting a hybrid model, but our team will have less learning to do due to Whistl’s exposure to and experience in diverse markets. This will result in fewer mistakes, which is why outsourcing remains a highly popular option for domestic and international online sellers.

Now that you’ve reviewed our advice on the best order fulfilment strategies, it’s time to look at our top tips to improve them and excel in your order fulfilment operations today.

  • Synchronise your eCommerce system with your fulfilment operations
