FULFILMENT DECISIONS
UK Fulfilment for Small Businesses: How to Choose a 3PL
If you ship a few dozen to a few hundred orders a month, a low pick fee is only one part of the decision. Start with the work you need, then compare the bill in both a quiet month and a busy one.
1. Decide what the warehouse needs to do
Write down the task before searching for a provider. A returns address that receives parcels is different from a fulfilment operation that imports orders, allocates stock, picks items and hands parcels to a carrier. A cheap returns subscription may solve the first task without solving the second.
| Your task | Ask for | Do not assume |
|---|---|---|
| Ship daily store orders | Order import, inventory sync, pick and pack, carrier handover and exceptions | A list of marketplace names proves a working integration |
| Handle UK customer returns | Receipt, item inspection, photos, grading and a decision on restocking | A parcel-receipt price includes opening, inspection or disposal |
| Store slow-moving stock | The actual chargeable unit, minimum space and goods-in/out handling | A “unit” means a pallet, or storage is your only charge |
For a mixed operation, list each task separately. If you only need returns, ask for returns-only terms: a provider’s full-fulfilment contract may not apply to that project.
2. Compare quiet-month cost, not just price per pick
Request the same operating profile from each candidate: monthly orders, items per order, active SKUs, parcel weight and size, average inventory, inbound deliveries, destinations and returned items. Also state a quieter month. A plan that fits 300 orders may be unattractive at 50 if a minimum invoice remains payable.
- A minimum order count is a volume condition.
- A minimum invoice is a billing floor, potentially covering only specified services.
- A fixed monthly fee may be added to usage charges.
A small quote can hide a large difference
The following numbers are invented to show the calculation, not quotes from listed providers. Assume all other charges and service scope are equal. Quote A charges £2 per order with no fixed fee. Quote B charges £60 each month plus £1 per order.
| Monthly orders | Quote A | Quote B |
|---|---|---|
| 30 | 30 × £2 = £60 | £60 + 30 × £1 = £90 |
| 60 | £120 | £120 |
| 100 | £200 | £160 |
Here, 60 orders is the break-even point for these two cost lines. If the £60 is instead a minimum invoice credited against picking, the formula changes to max(£60, eligible picking charges) + charges outside that minimum. Ask what counts toward the floor; adding a minimum to the same fees again would overstate the bill.
Storage also needs a common unit. A pallet-week converts to an average month using 52 ÷ 12, not four weeks. A unit-day rate cannot be compared with it until the provider defines the unit and the stock footprint. Use our adjustable UK budget sample to see the arithmetic, then replace missing items with written quotes.
3. Build a shortlist from evidence and gaps
Start with two or three candidates whose documented services fit your task. Keep an unconfirmed feature on your question list rather than treating it as a rejection. Our UK comparison separates documented matches from items needing confirmation; the display order is not a quality ranking.
- PackPro: its pricing page states no minimum volume and rolling monthly terms. Its summary and tier tables differ on some storage and receiving figures; ask for your applicable tier and what “unit” means.
- ReturnRev: its public plans describe no minimum order/return volume and 30 days’ notice. Check item acceptance, taxes and costs outside the listed operations.
- Returns-only options: compare receipt, inspection, storage allowance and forwarding separately in the ReturnsAddress record and Warehouse Address record. A returns plan is not evidence of automated daily order fulfilment.
These are starting points for research, not a promise that a provider will accept your products or perform well. We have not independently tested their warehouses. A large network or an approved affiliate relationship does not establish suitability for a small account.
4. Agree a first-month operating plan
Before moving all stock, agree an appropriate initial inbound shipment and the checks needed before orders go live. Verify SKU mapping, barcode and packaging rules, stock reconciliation, one representative order workflow and the process for a damaged return. Obtain permission before sending test stock or test orders.
- Who resolves a missing item, inventory mismatch or failed order import?
- What is the cut-off, and does the promise concern dispatch or delivery?
- What happens to stock and pending returns when you give notice?
- Which charges continue during a month with no outbound orders?
- How will the first invoice be reconciled against the agreed rate card?
Accept a candidate when the service fits, the quiet-month bill is affordable for your business, and the remaining questions have written answers. If a critical product restriction or integration is unresolved, keep it unresolved rather than replacing it with a score.
Use one operating profile for every candidate, then compare itemised replies.
