Amazon FBA Prep Checklist for UK Sellers Before Sending Stock

Most FBA prep problems are created before the first box reaches the prep centre. Weak references, unclear label rules, mixed cartons and no decision process for damaged stock all slow the shipment later. This checklist gives UK Amazon sellers a practical handover route before sending stock into ATP or any prep centre.

A clean FBA prep handover starts before stock reaches the warehouse.

Why it matters

A practical Amazon FBA prep checklist for UK sellers covering labels, packaging, references, damaged units, shipment plans and prep-centre handover.

Start with references, not boxes

A prep centre can only receive stock cleanly if the inbound is identifiable. Supplier order numbers, retailer order numbers, tracking references, shipment IDs and seller notes should be attached before the stock moves.

The goal is simple: when a parcel arrives, the warehouse should know who owns it, what it probably contains, and what decision is needed if the contents do not match expectation.

  • Use one seller reference consistently across purchase, delivery and prep notes
  • Keep tracking references visible for split deliveries and retailer parcels
  • Tell the prep centre whether a partial delivery should wait or proceed
  • Separate current shipment stock from future or storage stock

Confirm the FBA prep rules before labels are printed

Labelling is the visible part of FBA prep, but the risk is in the instruction. The prep centre needs to know whether units require FNSKU labels, suffocation warnings, bundling, poly bags, box protection, expiry-date handling or other SKU-level rules.

If the instruction is unclear, the right answer is to hold and ask. Guessing is how sellers end up with rejected shipments, damaged products or stock that has to be reworked.

Prep detailWhat to confirmWhy it matters
FNSKU labelsWhich SKUs require labelling and where labels should be placedWrong labels can create receiving or listing problems
BundlesWhich units make one sellable bundle and how they should be securedLoose or unclear bundles can be rejected or mis-sold
PackagingPoly bags, warnings, protection or carton rulesWeak packaging creates damage and customer complaints
Expiry or conditionAny date, condition or hold-before-action ruleSome stock should not be sent to FBA without review

Decide what happens when stock is wrong

Every useful handover includes an exception rule. If stock arrives damaged, short, incorrect or not ready for FBA, the warehouse needs to know whether to hold, photograph, rework, return, forward or wait for seller approval.

The best prep workflow slows down at the exception and speeds up everywhere else. That protects usable stock without waving questionable units into Amazon.

  • Ask for photos or notes before damaged stock is reworked
  • Keep shortage decisions separate from normal prep
  • Do not let unclear stock hold up a whole batch if the rest is ready
  • Agree who signs off returns, disposal or forwarding

Use a first batch as the test

A first batch should be realistic enough to test the workflow, but not so large that a mistake disrupts the whole operation. Include normal stock, normal references and at least one route you expect to use again.

Judge the result on receiving clarity, issue communication, prep accuracy and dispatch timing. If those work, scaling volume becomes a sensible operational decision rather than a leap of faith.

The practical checklist

  • Seller reference supplied
  • Tracking references supplied
  • FBA shipment or next destination clear
  • FNSKU, bundle and packaging rules clear
  • Shortage and damage decision rules agreed
  • Storage or hold logic agreed
  • Pricing confirmed before stock is sent
