Amazon FBA prep
Your Amazon inbound, prepped by the same team that ships your other orders.
FNSKU labeling, polybagging, breakpack, and bundle assembly, with every FNSKU scan-verified against the unit it goes on, from the same inventory pool that fulfills your own store. Prep comes with a fulfillment account here; we do not sell it on its own.
What it is
Prep is the work that gets a unit past Amazon's door
Fulfillment.com is a third-party logistics provider (3PL) that performs Amazon FBA prep in-house, inside your fulfillment account: FNSKU labeling scan-verified on every sellable unit, polybagging, breakpack to sellable units, bundle assembly, and cartons labeled to your shipment plan, out of the same inventory pool that ships your other channels.
Amazon FBA prep (Fulfilled by Amazon prep) is the labeling, bagging, bundling, and pack-out that a finished sealed unit needs before Amazon will receive it. Get it wrong and the shipment is refused, charged an unplanned-prep fee, or received against the wrong code, which is where wrong-item claims come from.
We do this as part of your fulfillment, not as a service on its own. Your inventory sits in one pool on our floor. Some of it gets prepped and sent into Amazon; the rest ships to your own customers. If you are shopping for a prep-only vendor that receives and forwards cartons and nothing else, we are not it.
If you prep with one vendor and ship everything else with another, that is two inventory pools, two counts, and a handoff every time demand moves between channels. The alternative is one pool and one team, which is what this is.
What we run
The prep we perform on your units
Every step below is physical work done on a unit in a building we operate, alongside the orders we already pick for you.
FNSKU labeling, scan-verified
The FNSKU (Amazon's per-unit barcode) goes on every individual sellable unit and is scanned against the SKU before it goes in the carton. A look-alike unit is caught before it ships under another unit's code.
Polybagging with the suffocation warning
Units that need a bag get one, with the suffocation warning printed where Amazon requires it and the bag sized so the unit is not loose. Missing or wrong bagging is a common reason Amazon flags a shipment and charges for prep it had to do itself.
Breakpack to sellable units
A case that arrives from your factory is broken down to individually sellable units, counted as it goes, so what Amazon receives matches what your listing sells.
Multipack and bundle assembly
Two-packs, three-packs, and mixed bundles are assembled to the spec you define and labeled as the bundle, not as the components, so the ASIN (the listing Amazon sells) is the unit we build.
Cartonized and labeled to your shipment plan
Prepped units are boxed to Amazon's carton and weight rules, packed so the carton holds up through the inbound leg and reads correctly at the receiving dock.
Shipment labels applied to your plan
Carton and pallet labels are applied to the shipment plan you filed, so what leaves our dock matches what Amazon is expecting to receive.
Start at the factory
The cheapest prep is the prep your factory already did
Many brands already have their cartons made Amazon-compliant at the factory: the barcode applied, the unit bagged, the case packed to spec. Where that is true, there is less prep to do here, and that is the best outcome for you. It is worth pushing your manufacturer toward it on the next run.
The catch is that it has to be verified, not assumed. A carton line that was compliant last run can change, and Amazon charges for the units that miss. So the units we prep are checked against the requirement as we handle them, rather than taken on the spec's word, and we tell you what we found.
Either way there is real work left. Even with compliant cartons we still run significant box-in, box-out volume: units come in on your inbound and go out prepped, labeled, and boxed to your shipment plan. Send us your product details and we will tell you which of your SKUs need labeling or bagging, which already arrive ready, and what that difference is worth.

Where it connects
Prep is one job on a floor that does the rest too
One pool, one team, and one platform, BestOMS (our order management system), across your Amazon inbound and every other channel you sell on.
Marketplace fulfillment
The channel mechanics behind this: how a marketplace order reaches us, and how it picks from the same stock position as your own store.
Kitting & assembly
Bundles and multipacks are assembled the same way for Amazon as for your own channels. See the assembly service and how contents are scan-validated.
Warehousing
Where the pool sits before you send it anywhere. You can place your stock across the nodes we operate, counted and visible in the portal.

FBA prep is one of the services run in-house by one accountable operator. See how the rest fit together.
Questions Amazon sellers ask about prep
Can I buy FBA prep on its own, without moving my fulfillment to you?
No. Prep runs inside a fulfillment account, alongside the orders we ship for your own store and your other channels. In practice that means one pool of your inventory on our floor: some units get prepped and go into Amazon, the rest ship to your customers, and both come off one count instead of two.
How do I know which of my units actually need prep?
You send us your product details and we come back with a per-SKU answer: which need labeling, which need bagging, which already arrive ready to go in. Where your factory has already made the cartons compliant, that is less to do here and less for you to pay for.
What does Amazon charge me for getting this wrong?
Amazon publishes the fees, and they are worth reading before you pick a prep arrangement. Units that arrive without required prep can be charged an unplanned-prep fee per unit, and Amazon may bag or label them for you at its own rate. Separately, inventory that sits in Amazon's network past its thresholds picks up long-term storage fees and aged-inventory surcharges. Those are charged on units inside Amazon's network, which is a reason to think carefully about how much of your pool you send in and when.
Who decides how much inventory goes into Amazon?
You do. You call the quantity and the timing, and we prep and ship what you call for. We hold the pool, give you live visibility on what is on hand in the portal, and turn your shipment plans around; we do not set your replenishment strategy for you.
Do you also ship the orders I fulfill myself?
Yes, and that is the usual arrangement. Merchant-fulfilled orders (Fulfilled by Merchant, or FBM) ship from nodes we operate, barcode-verified and routed to the node closest to your customer, from the same stock position that supplies your FBA shipments. One team answers for both.
Can you get me Seller-Fulfilled Prime?
Not today. Seller-Fulfilled Prime lets a seller keep listings Prime-eligible while shipping the orders themselves, and Amazon holds the seller to transit-time and on-time delivery requirements that it audits closely. The bar is on every order, not on an average. It is not a program we run today, and we would rather tell you that than sign you up for a standard we are not holding. If it is where your Amazon channel is headed, raise it in the quote conversation.
Are you a co-packer?
No. We handle finished sealed product. Prep means applying labels, bagging, bundling, and packing out units that are already made; it does not mean manufacturing, filling, bottling, or primary-packing your product.
Tell us what you sell and we'll tell you what needs prepping.
Send your product details, your volume, and how much of it goes into Amazon. You'll get back which SKUs need labeling or bagging, which need nothing, and a quote for the prep alongside the fulfillment for your other channels.
