UK 3PL Costs: What Brands Should Include When Comparing Fulfilment Quotes

A 3PL quote is only useful when it shows how the full fulfilment operation will be charged. A headline cost per order can leave out storage, inbound handling, packaging, shipping, returns and technology fees. The right comparison starts with your own products, order profile and service requirements, then adds up the costs across an average month and a peak month.

There is no single UK rate that applies to every brand. Pick-and-pack might be priced per order or per item, while other services may be itemised, charged separately or bundled into an agreed fee. Pricing also reflects product size, stock levels, handling needs, order complexity and the provider’s service model. A lower pick-and-pack rate can therefore produce a higher total bill if other charges are substantial.

Build the comparison around your operation

Different businesses need different fulfilment setups. A cosmetics brand, a public sector organisation and a subscription box business may have distinct product profiles, order patterns and service requirements. A quote needs to account for those differences instead of applying a standard rate to every operation.

Start with the expected total fulfilment cost for your own order profile. Ask each provider to itemise its services and explain whether each fee is fixed, variable or subject to a minimum. Compare like-for-like service levels and make sure the figures cover the same activities. Granby says it has more than 65 years of experience supporting brands across sectors and tailoring fulfilment to their operating requirements.

What a 3PL quote can cover

Fulfilment combines several warehouse and distribution activities. Some will be relevant to every account; others depend on the products, sales channels and customer experience a brand needs. A detailed quote should make clear which services are included and how each one is priced.

Inbound stock and inventory receipt

When stock arrives, the provider may need to check quantities, record the delivery and allocate storage space. The quote should state whether receiving is included and how any extra checking, counting or sorting is charged. Granby says it assigns products SKUs in its warehouse system so stock can be identified, tracked and traced through fulfilment.

Storage

Storage rates may be based on pallets, bins, shelves, cubic metres or another agreed unit. The amount charged depends on stock volume and the storage arrangement. Some goods need specific procedures or conditions: food products, for example, may call for temperature-controlled storage or particular handling.

Ask how the provider protects inventory and keeps records accurate, and how it handles product-specific requirements such as expiry dates. Granby describes storage controls that include a caged area for high-value goods, CCTV and on-site security. Details are available on its storage and distribution page.

Picking, packing and materials

Picking and packing rates can vary with the number of items in an order, the work involved, packaging requirements and agreed volumes. Multi-item, customised or unusual orders may require more labour than a straightforward single-item shipment. Granby says its in-house team can draw on bank staff during busy periods, and it also offers contract packing.

Packaging is another cost to identify. Boxes, tape, protective materials and other components all affect the charge, as does the choice between plain and branded materials. Packaging must suit the product and journey: Granby cites personalised ribbons made for a large chocolate brand for Easter as one example of bespoke work. Check whether standard materials are included and how the provider prices custom or specialist packaging.

Shipping and returns

Distribution costs depend on destination and service level, including whether goods travel within the UK or internationally. Providers may use established carrier networks, consolidate shipments or plan deliveries to improve transport efficiency. Granby says it works with carrier partners and plans deliveries to reduce unnecessary journeys, alongside its sustainability efforts. The quote should set out the services and charges that apply to your lanes.

Returns are part of the fulfilment model, too. A provider may inspect returned goods, check for faults or damage and determine whether an item can be restocked, refurbished or disposed of safely. Each step can carry handling costs. A clear returns process can also help recover stock that remains suitable for resale and limit avoidable waste. Granby outlines its approach to reverse logistics and returns management and its reverse logistics services.

Reporting, account support and extra services

Some providers include account management and reporting in their service; others charge for enhanced support or more detailed reporting. Ask what data you can access, how often it is updated and whether system access has a separate cost. Granby says it uses KPIs in its software to keep brands informed about performance and progress.

Value-added work can include kitting, personalisation, relabelling, repacking, assembly, quality checks and promotional fulfilment. These services can support specific product launches, customer requirements or seasonal activity, but the labour and materials should be reflected in the quote. Granby also describes its work in high-volume contract packing.

Because these activities sit alongside storage and delivery, two quotes with the same cost per order may cover quite different services. The comparison should capture the full scope of work before you judge the rates.

What can push costs up or down

Several features of a business change the amount of warehouse space, labour, transport or system support it needs:

• SKU count: A broader range can mean more inventory records, storage locations and handling steps.
• Product size and weight: Larger or heavier goods may take up more space and cost more to ship.
• Order complexity: Multi-item and customised orders can take longer to pick and pack.
• Seasonal peaks: Busy periods may call for more staff and operating capacity.
• Sales channels: Different channels can require distinct fulfilment solutions and system connections.
• International shipping: Customs processes, carrier options and destination requirements add work.
• Special handling: Fragile, sensitive or specialist products may need extra procedures.
• Returns volume: More returns bring additional inspection and processing.

These factors can also interact. A seasonal increase in orders, for instance, may coincide with higher stock levels and more complex picking. Ask how the provider plans for changes in demand and what happens if your volumes or storage needs differ from the estimate. Granby says it can scale with clients and draws on its experience to manage busy periods while maintaining its service standards.

Charges to clarify before signing

A headline quote may not include every variable fee. Ask the provider to explain the following items and give examples of when they apply:

• Minimum monthly spend: Is there a minimum charge when volumes fall below forecast? Which services count toward it?
• Inbound handling: Is receiving charged per pallet, carton, SKU or delivery? Do counting, checking or sorting cost extra?
• Additional picks: Is pick-and-pack priced per order, item or another unit? How are multi-item, split or non-standard orders charged?
• Storage overages: What happens when stock exceeds the agreed allowance, including during seasonal peaks?
• Returns processing: Are inspection and restocking included? What fees apply to damaged, faulty or unsaleable items?
• Setup and project work: Are onboarding, stock migration, warehouse setup, process changes or project work charged separately?
• Packaging surcharges: Are standard materials included? How are branded, bespoke, oversized or fragile shipments priced?
• Technology and integrations: Are system connections included? Ask about setup and ongoing fees for ecommerce, ERP or order management links, API access, custom reporting and system changes.
• Special handling: How are fragile, high-value or temperature-sensitive products priced? Ask about fuel surcharges, labelling, repacking and manual quality checks.
• Peak-period surcharges: When do these apply, which services do they affect, and are they already reflected in the quoted rates?
• Exit and offboarding: Confirm notice periods, minimum commitments and any fees for stock counts, stock removal, data transfer or closing integrations.

Put the answers alongside the quoted rates. That makes it easier to see where actual costs could differ from the headline figure.

Estimate total monthly fulfilment cost

A useful starting calculation adds together the services your business needs:

Estimated monthly fulfilment cost = receiving + storage + pick-and-pack + packaging + shipping + returns + account and technology fees + value-added services + other applicable charges

Then divide that total by the number of orders:

Estimated cost per order = total monthly fulfilment cost ÷ monthly orders

Run the calculation for both a typical month and a peak month. The result is an estimate for comparison, since providers structure their fees differently. Share accurate information about your orders, stock and products so that each provider can build its quote from the same operating assumptions.

Service quality belongs in the cost comparison

A low quote can conceal operating issues that create extra work and customer service problems. Stock inaccuracies, delivery delays, poor inventory visibility, slow responses, inflexible processes, limited reporting and difficulty scaling during busy periods can all disrupt fulfilment. The provider’s experience, systems and ability to adapt matter alongside the rates.

Granby says its in-house-built technology, including its warehouse management system, provides visibility from goods-in and inventory management through distribution and returns. When assessing any provider, ask how its systems support stock accuracy, reporting and day-to-day operational control.

What to look for in a quote

A useful quote should give you a clear pricing structure, defined service-level agreements, reporting details, inventory management processes and information about technology access. It should also explain returns handling, account support and how capacity can scale as demand changes. Transparency means you can see what you’re paying for and what service you should expect.

Make sure every provider is pricing the same work at the same service level. Before requesting quotes, assemble your own operating details: average items per order; product dimensions and weights; typical stock levels; SKU count; returns rate; seasonal peaks; sales channels; international destinations; specialist handling and packaging needs; reporting requirements; and any need for kitting, contract packing or personalisation. Include the customer experience you want to deliver and your expected growth over the next three years.

That information helps providers price the operation you need, while giving your team a consistent basis for comparison. The best fit is the quote that makes its costs and service commitments clear and can accommodate your operating profile as it changes.
