What is a 3PL? Third-party logistics, explained for UK sellers
What a 3PL does step by step, how it differs from a 2PL, a 4PL or Amazon FBA, and what it really costs, with a worked monthly bill from a published rate card.
What we learn running a UK fulfilment operation, written for sellers from 100 orders a month upwards. No listicles, no reheated press releases.
The Angler dispatch
Most fulfilment content is written by people who have never picked an order. These are written by people who have. If something here is wrong or has changed, tell us and we will correct it.
Every Angler client now has a secure portal account: onboarding documents, invoices you can query line by line, payment confirmations, and a ticketed message thread that reaches the floor, not an inbox.

Most sellers find out a 3PL was the wrong choice when the first invoice arrives. The twelve questions that surface it first, the red flags, and a checklist to send.
The carrier’s posting date is not your deadline. The arithmetic that turns one into the other, and what to put on the site while you wait for this year’s dates.
The 14 day rules in plain English, the real arithmetic on a returned order, and the five changes that cut return rates fastest.
Royal Mail prices rise on 5 October, a peak surcharge runs from 2 November to 10 January, and Amazon’s fees moved the other way. The calendar, with the arithmetic.
The thresholds are higher than the headlines suggest, and 25 tonnes is a lot of boxes. Where the line sits, what each side has to do, and why your cartons carry the fee regardless.
Amazon has ended in-house prep. What FNSKU labelling requires in 2026, what a prep centre should cost, and how to choose one that will not get your shipments rejected.
Most 3PLs will not return your call at this size. Every real option compared with honest numbers: DIY, FBA, big 3PLs and a small-seller specialist.
Rate targets, ten-hour shifts and algorithmic management, and what giant-warehouse turnover quietly means for sellers whose stock lives there.
Parcel stamps go up by 35p to £1.45 while franked and account prices hold. What the change costs at 100 to 2,000 parcels a month, and the three ways round it.
Quoted 85p a pick and then billed 40% more? The charges 3PLs put in the contract rather than the price list, and the five questions that flush them out.
Onboarding slips because of missing barcodes and unmeasured products, not because of the warehouse. Everything to have ready before your stock leaves.
By the time Black Friday traffic arrives, every decision that matters has already been made. What to lock down while it is still quiet.
Nothing matches that search yet.
