A competitive courier rate can make a fulfilment quote attractive. However, the true cost of e-commerce fulfilment extends beyond delivery. From receiving and storing inventory to picking, packing and processing returns, every stage contributes to operating expenses. For growing UK businesses, understanding these costs is essential for comparing third-party logistics (3PL) providers and protecting profit margins.
Why the Advertised Fulfilment Rate Isn’t the Full Cost
Fulfilment providers may charge separately for storage, packaging, handling and delivery. Others bundle certain services into one rate, making direct comparisons difficult. In July 2026, Logistics UK reported that vehicle operating costs rose by more than 12% in the year to April 2026, highlighting wider financial pressures across the industry. Although this does not represent a universal increase in fulfilment prices, it reinforces the importance of reviewing additional charges and contract terms.
Five Fulfilment Costs Businesses Often Overlook
1. Warehouse Storage and Handling
Storage charges may depend on pallet space, inventory volume and storage duration. Receiving mixed shipments, checking stock discrepancies and preparing goods for storage can create additional handling costs. Seasonal businesses should also consider whether warehouse capacity and charges can adjust as inventory requirements change.
2. Picking, Packing and Packaging
Processing costs vary with order complexity, item quantities and packaging requirements. Multi-item orders, product bundles and promotional inserts may require additional handling. Packaging also influences delivery efficiency. Logistics Manager explored how right-sized packaging reduces wasted space, while Warehouse & Logistics News reported on technology designed to improve packing efficiency.
Businesses should assess whether packaging protects products without unnecessary material or shipping expenses.
3. Courier Charges and Surcharges
Advertised delivery rates may exclude additional charges based on parcel weight, dimensions, destination or delivery speed. Fuel adjustments, oversized-parcel fees and peak-season surcharges may also apply. Comparing quotations against actual shipment profiles provides a clearer picture of expected expenditure.
4. Returns Processing
Returned goods often require inspection, grading, repackaging and inventory updates before becoming available for resale. These activities create handling costs, while processing delays can leave valuable stock unavailable for customers. Businesses should assess both returns-processing charges and the time required to return suitable products to inventory.
5. Operational Capacity and Additional Services
Low fulfilment rates provide limited value when operational problems cause delays or unexpected expenses. In 2025, Logistics Matters reported fulfilment capacity challenges affecting retailer The Works, including higher costs per order. This highlights why operational reliability, available capacity and transparent charges matter alongside price.
How to Calculate Fulfilment Cost per Order
A useful calculation is: Average fulfilment cost = Total monthly fulfilment costs ÷ Orders fulfilled
Consider a hypothetical UK retailer dispatching 1,000 orders in 1,000 parcels each month.
| Included Monthly Charges | Example Cost |
|---|---|
| Receiving and storage | £300 |
| Picking and packing | £1,200 |
| Packaging materials | £350 |
| Courier delivery and surcharges | £3,300 |
| Returns processing | £110 |
| Other agreed service charges | £50 |
| Total | £5,310 |
Figures are illustrative, not actual TLB rates, customer results or UK market averages.
Average cost: £5.31 per order.
The example includes the six listed cost categories, including assumed delivery surcharges and routine returns handling. It excludes VAT, product purchases, marketing, payment processing, import duties, one-off setup and unlisted specialist services.
Understanding these components provides a more accurate comparison than relying on courier or pick-and-pack rates alone.
When Should Businesses Review Their 3PL?
Unexpected charges, limited capacity and poor inventory visibility can indicate that an existing fulfilment arrangement needs reviewing. A 2026 Logistics Business article examining signs that companies have outgrown their 3PL highlights challenges involving visibility, network limitations and disconnected systems. Changing providers is not always necessary. Reviewing existing processes, service performance and commercial terms may identify opportunities for improvement.
