UK Amazon FBA prep centre · FNSKU labellingAmazon FBA prep, done right so defect fees never hit you

The full list

Every prep service, itemised

Nothing here is bundled into a vague “prep” line. You pay for what each SKU actually needs.

Inspection and counting

Every carton opened, checked against your ASINs and counted in. Damaged or short stock is flagged and photographed before it travels anywhere, which is the difference between a supplier conversation and an Amazon problem.

FNSKU labelling

The correct FNSKU applied to each unit, covering any existing manufacturer barcode as Amazon requires, so units scan to your listing and not somebody else's. That last part is the whole point of labelling. Unlabelled units go in stickerless and commingled, pooled with every other seller's copies of the same ASIN, and the unit your customer opens is whichever one Amazon happens to pick off the shelf. If that unit is a counterfeit or somebody else's damaged copy, the return and the one-star review arrive on your account. An FNSKU is how you ship your own stock and get your own stock back.

Polybagging

Poly-bagged to spec, with the suffocation warning printed on bags at or above the size Amazon sets the threshold at. This is one of the most common reasons a shipment gets flagged. Where a product has to be concealed rather than simply protected, the bag is opaque instead of clear.

Bundling and kitting

Multi-packs and bundles assembled and labelled as a single sellable unit, so what arrives at the fulfilment centre matches what your listing sells. Where Amazon treats the group as a set, the units are bagged together and marked sold as set, do not separate. A set that arrives loose gets split on receipt and counted as single units against the wrong listing, which is slow and awkward to unpick afterwards.

Bubble wrap and fragile prep

Protective wrap for fragile or breakable items, applied so they survive being handled several more times inside Amazon's network than they would on a direct order.

Expiry and date labelling

Date labelling and stock rotation for products Amazon treats as expirable, supplements being the common case. Priced per SKU rather than per unit, because the work depends on how your dates are printed and where.

Box content information

Every box in an FBA shipment has to declare what is inside it, by SKU and quantity, before it reaches the fulfilment centre. Without it the boxes arrive unidentified, Amazon works the contents out itself and charges for doing so, and your stock sits uncountable while that happens. We send the box content with the shipment, whether the cartons are case-packed with one SKU each or individually packed with a mix, so the shipment checks itself in.

Carton forwarding to Amazon

Repacked into compliant shipping cartons, labelled with your Amazon shipment IDs, and dispatched to the fulfilment centre. Shipment plans are created in your Seller Central so the paperwork matches the pallet.

Questions sellers ask about FBA prep

FBA prep, answered straight

Do you apply FNSKU labels?

Yes. We apply the correct FNSKU to each unit and cover any existing manufacturer barcode, exactly as Amazon requires, so units scan to your listing rather than to another seller's.

Can you polybag and bundle?

Yes. We poly-bag to spec with the suffocation warning where the bag size requires it, and assemble bundles or multi-packs as single sellable units so the unit matches what your listing sells.

Will you forward my stock to the Amazon fulfilment centre?

Yes. We repack into compliant cartons, create the shipment plan in your Seller Central, apply your Amazon shipment labels and dispatch to the fulfilment centre. Carton forwarding is charged at carrier cost plus £2.50 per carton handling.

What does FBA prep cost?

From 55p per unit for receive, inspect and FNSKU label, falling to 45p and then 40p as volume rises. Polybagging, bubble wrap and bundling are itemised separately on the rate card, and expiry labelling is quoted per SKU. One invoice, in pounds sterling, with no minimums.

Can you handle FBA prep and my direct-to-consumer orders together?

Yes. Both run from one stock pool in our warehouse, so you can sell direct on Shopify or TikTok Shop and send stock into FBA from the same inventory, with one contact and one invoice. It also means you have an FBM fallback ready if FBA stock strands.

How accurate is your prep, and what happens if you get one wrong?

Our published commitment is 99.5% dispatch accuracy or better, reported to you every month, and measured pick accuracy across the warehouse averages 99.8%. That figure covers order picking rather than prep specifically, and it is quoted because the same team does both. If we label or pack a unit wrong, we put it right at our cost, and if Amazon charges you unplanned prep because of something we did, that is ours to cover too.

How quickly is my stock ready to prep?

We book goods into stock within 48 hours of arrival, then prep and forward on your schedule. Book the delivery in with us before it travels, or it sits in goods-in instead of going to a shelf.

Did Amazon really stop offering prep in the UK?

Yes. Amazon's wording is that from 1 July 2026 it no longer offers prep and label services for FBA shipments in its European stores, which includes the UK. Guidance written for the US market often quotes January 2026 instead, because that is when the equivalent change happened there.
