An Amazon FBA prep center is a third-party facility that receives your inventory, prepares it to meet Amazon's requirements, and ships it directly to Amazon's fulfillment centers on your behalf.
What Does an FBA Prep Center Do?
- Receives inventory from your supplier
- Inspects products for damage or defects
- Applies FNSKU labels and barcodes
- Poly-bags, bubble-wraps, or kits products as required
- Creates Amazon shipment plans in Seller Central
- Ships inventory to assigned Amazon FCs
Do You Need a Prep Center?
You need a prep center if: your supplier can't prep to Amazon's standards, you're scaling beyond what your home/office can handle, you want to avoid Amazon's costly FBA prep fees ($0.55–$3.00+ per unit), or you want to take advantage of a tax-advantaged state like Delaware.
Prep Center vs Amazon Prep
Amazon offers their own prep service — but at steep per-unit rates ($0.55 per label, $1.35+ per bagging). A third-party prep center like QuickShipment typically costs 30–50% less, with the added benefit of tax-free Delaware pricing.
How to Choose a Prep Center
- Location: Delaware for tax savings, proximity to Amazon FCs
- Turnaround time: 48 hours is the benchmark to beat
- Pricing transparency: flat per-unit rates, no hidden fees
- Compliance record: ask about their Amazon acceptance rate
- Communication: same-day responses, real account managers
💡 QuickShipment checks all these boxes — 48-hour turnaround, Delaware location, 99.8% acceptance rate, and a dedicated account manager for every seller.
What Changed on 1 January 2026
Until the start of 2026, a seller who got prep wrong had a fallback: Amazon would fix it and bill for the service. That fallback is gone. Amazon ended its US FBA prep and item labelling services on 1 January 2026, and units that arrive unprepared are now refused or handled under unplanned-services terms at the seller's cost.
This is why "do I need a prep centre" stopped being a cost question and became a process question. Somebody has to prep the units before they ship — the factory, you, or a third party. What changed is that Amazon is no longer one of the options.
What the Work Actually Is
Prep is a checklist, not a craft. Every unit needs:
- An inspection — transit damage, factory defects, missing components. Catching a bad unit here costs nothing; catching it at Amazon costs a removal order.
- Every existing barcode covered — UPC, EAN, supplier codes. An exposed old barcode is the most common cause of a unit being logged against the wrong ASIN.
- An FNSKU applied correctly — flat surface, no seams or curves, printed at 100% scale.
- Category-specific protection — a poly bag with a suffocation warning where the opening is five inches or more, bubble wrap for fragile items, sets bagged as one sellable unit.
- Carton build and labelling — weights and dimensions recorded, carton labels applied, shipment plan created.
None of it is difficult. All of it is repetitive, and the failure modes are boring rather than dramatic — which is exactly why they get missed at volume.
Prep Centre, Supplier or Yourself — the Real Comparison
| Cost per unit | Works well when | Fails when | |
|---|---|---|---|
| Yourself | Materials only, plus your time | Under ~300 units/month, one simple SKU | Volume rises; your time becomes the constraint |
| Supplier | Often lowest at volume | Factory proves compliance with photographs | Label scaling, missing warnings, no US returns point |
| Prep centre | $0.70–$2.50 typical US range | Volume, multiple SKUs, imports, returns | Very low volume — the per-unit rate is highest there |
Supplier prep deserves a fair hearing: at high volume it is frequently the cheapest option and good factories do it well. The two things to check before relying on it are the FNSKU print scale — supplier prep fails on this more than anything else — and whether you have a US address for returns, which the factory cannot provide.
The Crossover Point
Self-prep looks free because your own time is not on the invoice. Put a value on it and the picture changes. Prepping 500 units at three minutes each is 25 hours; at any sensible hourly rate that is more than the prep bill.
For most sellers the crossover sits somewhere between 300 and 800 units a month, depending on how complex the prep is and what your time is worth. It is worth calculating for your own case rather than taking anyone's word for it — including ours. Our cost calculator runs the third-party side of that comparison.
Six Questions Before You Choose One
- What is included in the per-unit price? Labelling included or extra? Receiving free or billed?
- What stops the stated turnaround? Short carton counts, unquoted prep, restricted items.
- Do they photograph at receiving? The evidence you need in a dispute months later.
- What will they refuse? A prep centre that accepts everything is about to have a problem.
- Is the minimum a volume floor or a monthly fee? They behave very differently in a slow month.
- What state is it in? Sales tax on domestic purchases, and distance to the fulfilment centres.

Frequently Asked Questions
Do I still need a prep centre in 2026?
Somebody has to prep the units — Amazon stopped doing it in the US on 1 January 2026. The options are your supplier, yourself, or a prep centre. Amazon is no longer one of them.
What does an FBA prep centre do?
Receives and inspects inventory, covers existing barcodes, applies FNSKU labels, adds required protective packaging, builds and labels cartons, creates the shipment plan and ships to the fulfilment centres Amazon assigns.
At what volume does a prep centre start to pay?
Usually between 300 and 800 units a month, once your own time is priced in. Below that, self-prep is genuinely competitive because the per-unit rate is at its highest.
Can my supplier do the prep instead?
Often yes, and at volume it is frequently cheaper. Check the FNSKU is printed at 100% scale and ask for photographs of prepped units before the run — label scaling is where supplier prep fails most often.
Does the prep centre's state matter?
It affects two things: sales tax on domestic inventory purchases routed through it, and transit time to the fulfilment centres. Delaware has no state or local sales tax and sits on the East Coast corridor.
