If you sell online in the UK, you’ve probably reached the point where packing orders yourself stops making sense. Boxes pile up in the spare room, peak season becomes a scramble, and every hour spent on parcel labels is an hour not spent growing the business. That’s usually when brands start looking at 3pl fulfilment.
Outsourcing is a smart move, but the pricing can be confusing. Quotes that look cheap at first often balloon once the first invoice arrives, thanks to extra charges nobody mentioned. This guide explains how 3PL fulfilment pricing works in the UK, where hidden fees tend to lurk, and how to choose a partner you can trust.
What Is 3PL Fulfilment?
A third-party logistics (3PL) provider stores your stock, picks and packs your orders, and ships them to your customers. Your products sit in their warehouse, your online store connects to their system, and orders flow through automatically.
The benefits are clear: lower overheads, faster delivery, scalability during busy periods, and more time to focus on product and marketing. But those benefits only materialise if you understand what you’re paying for.
The Core Components of 3PL Fulfilment Pricing
Most UK providers build their pricing from the same handful of elements. Knowing each one helps you compare quotes properly.
1. Onboarding and Setup Fees
Some providers charge a one-off fee to integrate your store, configure your account and set up your products in their warehouse management system. This is reasonable when it covers real work, but it should be clearly itemised. Ask exactly what’s included, and whether the fee is waived on longer contracts.
2. Receiving and Goods-In Charges
When your stock arrives at the warehouse, it has to be unloaded, checked, counted and put away. Providers usually charge per pallet, per carton or per hour. Watch for differences in how they handle mixed pallets, unlabelled cartons or inbound deliveries that don’t match your advance shipping notice. These are common triggers for extra charges.
3. Storage Fees
Storage is normally charged per pallet, per shelf or per bin, either weekly or monthly. Some providers charge by cubic volume instead. The key questions are:
-
How is storage measured, and how often?
-
Is there a minimum monthly storage commitment?
-
Do charges increase for slow-moving or long-term stock?
A low headline rate can hide a minimum spend that makes it far less attractive for a small brand.
4. Pick and Pack Fees
This is the charge for finding each item, packing it and preparing it for dispatch. It’s usually a fixed fee for the first item in an order, with a smaller fee for each additional item. Check whether packaging materials such as boxes, void fill and tape are included or billed separately.
5. Shipping and Carrier Costs
Delivery is often the biggest part of your bill. Providers typically pass on carrier rates from the likes of Royal Mail, DPD, Evri or DHL, sometimes with a handling margin on top. Rates vary by weight, size, destination and service level. Ask whether you’ll get the provider’s negotiated rates and whether surcharges for remote postcodes, fuel or peak periods apply.
6. Returns Handling
If you sell fashion, beauty or anything with high return rates, this matters a lot. Providers may charge to receive, inspect, restock or dispose of returned items. Clarify what’s included and whether there’s a separate fee for relabelling or repackaging.
The Hidden Fees to Watch Out For
Here’s where costs creep up. When comparing 3pl fulfilment providers in the UK, look closely for these.
Minimum monthly fees. Some providers require a minimum spend regardless of order volume. If your sales dip in quiet months, you’re still paying the minimum.
Account management or admin fees. A flat monthly charge for “account support” or “system access” is common. It isn’t always disclosed upfront.
Special handling charges. Fragile items, oversized goods, bundles, kitting, gift wrapping and inserts often cost extra. If your products need anything beyond standard picking, get these costs written down.
Peak season surcharges. Come November and December, some providers raise pick and pack rates, or carriers add peak surcharges. If you rely on Black Friday and Christmas sales, ask for seasonal pricing in advance.
Inbound error fees. Incorrect labelling, missing paperwork or booking errors can trigger charges for rework. Ask what the provider expects from you and what happens if something goes wrong.
Long-term storage penalties. Stock that sits for months may attract higher rates. This is worth knowing if you buy in bulk or carry seasonal lines.
Contract lock-ins and exit fees. Long minimum terms and notice periods can be costly if the relationship isn’t working. Some providers also charge to release or transfer your stock when you leave.
Technology or integration fees. Connecting to Shopify, WooCommerce, Amazon or other platforms may be free with some providers and chargeable with others. Don’t assume it’s included.
How to Compare 3PL Quotes Properly
A cheap per-order price doesn’t always mean a cheap service. Here’s how to compare fairly.
Use your real numbers. Give every provider the same data: average orders per month, typical order size, SKU count, average parcel weight, return rate and seasonal peaks. Quotes built on vague assumptions are unreliable.
Ask for a full cost breakdown. Request a sample invoice or a worked example showing a typical month. This shows you the total cost, not just the headline rates.
Calculate cost per order. Add up all fees, including storage, packaging, shipping and admin, then divide by the number of orders. This “all-in” figure is the only fair way to compare providers.
Model different scenarios. Work out what you’d pay in a quiet month, a normal month and a peak month. A provider that looks good at average volumes may be expensive at the extremes.
Check the contract. Read the terms around price increases, notice periods, liability and exit costs. Hidden fees often sit in the small print, not the quote.
Questions to Ask Any 3PL Provider
Before you sign, put these questions to every provider on your shortlist:
-
Are there any fees not listed in this quote?
-
Is there a minimum monthly spend or minimum order volume?
-
How are storage charges calculated and when are they invoiced?
-
Are packaging materials included in the pick and pack price?
-
How are returns handled and charged?
-
What peak season surcharges should I expect?
-
How often can you change your prices, and with how much notice?
-
What are the contract length, notice period and exit terms?
-
Do you charge for integrations, reporting or customer support?
-
How do you handle errors, damaged goods or lost stock?
A transparent provider will answer these clearly and in writing. If answers are vague or evasive, treat that as a warning sign.
The Value of Transparency
Price matters, but it isn’t everything. A slightly higher rate from a provider with clear, predictable billing often costs less in the long run than a bargain quote full of surprises. Predictability lets you forecast margins, set the right prices and plan growth without worrying about unexpected invoices.
Look beyond price too. Consider accuracy, dispatch speed, communication, technology and how well the provider understands your business. Late dispatches, picking errors and poor customer service all cost you money in refunds, lost customers and bad reviews, even if they never appear on an invoice.
