Beginners keep asking which one to hire, and the honest answer is that they're not alternatives. The forwarder moves your cargo across oceans and through import logistics; the prep center opens the cartons on this side, counts, inspects, labels and forwards compliant inventory into FBA. This page draws the line between the two roles, marks where the baton passes, and lists what neither of them will ever do for you.
The confusion is understandable, because both are 'logistics companies' and both touch the same shipment. The clean test is the carton seal. A forwarder's entire world is sealed freight: containers, master cartons, pallets, manifests. It neither knows nor cares that carton 14 holds size-M hoodies wearing size-L labels. Its success metric is cargo arriving where the documents say, when the schedule says.
A prep center's world begins when the seal breaks. Units get counted against the purchase order, condition gets photographed, variants get verified, and every unit gets whatever Amazon's current requirements demand — FNSKU labels, poly bags with warnings, bundling, expiration dates — before cartons are rebuilt with matching box content data and handed to a carrier for Amazon.
One boundary deserves bold print: customs. Clearance into the US runs through your forwarder and its customs partners — a prep center is not a customs broker, and ProShip3PL is not an Importer of Record. We recommend DDP terms so your goods arrive already cleared and duty-paid. Any warehouse that vaguely implies it 'handles customs' is describing someone else's job.
Why the sequence matters more since 2026: Amazon no longer performs prep or labeling in the US, so a container routed factory-direct into FBA carries every factory error straight to check-in, uninspected — and unprepped goods that get damaged or lost sit outside reimbursement. The prep center between forwarder and Amazon is the only inspection the chain has left.
| Responsibility | Freight forwarder | Prep center |
|---|---|---|
| Ocean / air cargo booking | Yes — core job | Never |
| Customs & import logistics | Via its customs partners | No — not a broker, not an IOR |
| Unit counts & inspection | No — freight stays sealed | Yes — against your PO, with photos |
| FNSKU labels, bags, bundles | No | Yes — to Amazon's current requirements |
| Storage & FBA replenishment | Transit only | Yes — monthly for space used, 24–48h triggers |
| Your Seller Central account | Neither — that stays with you | Neither — that stays with you |
Knowing whose phone to ring, for which problem, is half of running an import chain calmly.
Vessel space, air cargo, routing choices, transit insurance conversations, port congestion workarounds. If the problem exists between two countries, it's a forwarder problem.
Clearance, duties and import formalities flow through your forwarder's customs partners. Ship DDP and the goods reach our dock already settled — the arrangement we recommend to every importer.
The first honest count since the factory happens at receiving: units versus PO, condition on camera. Forwarders move what they're given; we tell you what you actually got.
Scan-verified FNSKU labels, bags with warnings, bundles, expiration dating, compliant cartons and pallets — the unit-level craft no forwarder offers and Amazon itself stopped providing in 2026.
A container rarely should go into FBA all at once. We split freight between immediate FBA shipments and stored stock that follows on your replenishment triggers — to a carrier within 24–48 hours of each trigger.
Shipping plans, listings, pricing, seller performance — neither role touches your Seller Central beyond the data you share. Anyone promising otherwise is overselling.
Your forwarder books the move from the factory, manages export and import logistics, and — on DDP terms — lands cleared goods in the US.
Container, pallets or cartons deliver to Medley, FL — about 25 minutes from PortMiami. The receiving report we produce is the baton-pass record.
Count, inspect, photograph; label, bag, bundle to Amazon's current requirements; rebuild cartons with accurate box content.
Compliant freight to the carrier within 24–48 hours; the rest onto our racks, flowing into Amazon on your replenishment triggers.
They can — as a trucking move. What that route skips is every count, inspection and label check between factory and check-in. One seller's 'direct savings' became a mislabeled container Amazon couldn't receive. Now the same containers stop here first.
A common and expensive assumption. Clearance belongs to your forwarder's side of the chain; we receive cleared freight. We flag this at onboarding and recommend DDP precisely so nobody discovers the gap at a port.
The forwarder's job isn't finished until delivery at our dock — that last truck leg is theirs to book. Give them our address before the vessel sails and the leg gets planned instead of improvised at demurrage rates.
With freight routed factory-direct, nobody can prove anything. With a prep center in the chain, our dated, photographed receiving count answers the question — and tells you whether to chase the factory or file with Amazon.
A freight forwarder is a transportation organizer: it books ocean or air cargo space, manages export and import logistics, and moves your goods between countries. A prep center is a warehouse operation: it receives those goods in the US, counts and inspects them, applies Amazon-required prep and labels, stores overflow, and forwards compliant shipments into FBA. The forwarder's job ends where the prep center's job begins — at a US dock.
If you import from overseas, almost always yes — they solve different problems. Without a forwarder, your goods have no ride across the ocean. Without a prep center (or your own US operation), the goods that arrive have no one to count them, catch factory defects, apply compliant labels or fix packaging before Amazon's receiving judges them. Domestic-only sellers who buy from US wholesalers can often skip the forwarder entirely.
Physically, yes — many will book a truck to an Amazon fulfillment center. Whether you should is another matter: nothing gets inspected, counted or corrected between your factory and Amazon's dock. Since Amazon stopped providing prep and labeling services in the US on January 1, 2026, any factory error rides straight into check-in, and damaged or lost unprepped goods fall outside reimbursement. Direct delivery works only when you fully trust the factory's prep — the first time it's wrong, you'll wish something had been in between.
No — and be suspicious of any warehouse that blurs this. ProShip3PL is not a customs broker and not an Importer of Record; clearing your goods into the US is arranged through your forwarder and its customs partners, and we recommend shipping DDP so duties and clearance are settled before arrival. Our work starts when cleared freight reaches our Medley, FL dock, about 25 minutes from PortMiami.
At our door, physically and contractually. The forwarder (or its trucker) delivers the container, pallets or cartons to 8871 NW 102nd St, Medley, FL 33178; we unload, count against your PO, and photo-document condition. That receiving report is the handoff record: it establishes what actually arrived, which matters enormously if the count disagrees with what the factory claims it shipped.
Book vessel and aircraft space, negotiate international freight rates, issue transport documents, coordinate export formalities at origin, route cargo through ports, and manage the import logistics chain with customs partners. A prep center owns none of that. When your container is stuck at a port, that's a forwarder conversation; when your units need labels before Amazon will take them, that's ours.
Open your cartons. A forwarder moves sealed freight; it doesn't count units against your purchase order, photograph damage, verify variants, apply FNSKU labels, bag, bundle, build Amazon-compliant cartons with box content data, store overflow inventory, or split a container across FBA, storage and other channels. Those unit-level operations are the entire job of a prep center.
Plenty, and knowing it saves painful assumptions. Neither runs your Seller Central account, creates your shipping plans, sources or pays your supplier, guarantees your goods clear customs, or makes your product legal to sell in the US — product compliance and import eligibility stay with you as the seller. A good prep center will flag obvious problems it sees on the bench, but flagging is not the same as owning the responsibility.
Three habits: give your forwarder our receiving address and delivery requirements before the goods ship, so the last mile is planned rather than improvised; send us the PO, packing list and ETA, so our dock expects the freight and can book it in fast; and keep both parties aware of each other's contact for delivery scheduling. Sellers who connect the two upfront get containers unloaded and into prep within days; sellers who don't get storage fees at a port.
We unload the container or accept the pallets, count everything against your PO with a photo-documented condition report, then prep to Amazon's current requirements — FNSKU labels scan-verified, bagging, bundling, carton builds with box content data. Compliant freight hands to a carrier for Amazon within 24–48 hours; anything you want held goes into bin or pallet storage billed monthly for the space used. Rate sheet within one business day, no setup fees, no minimums.
Tell us where your freight originates, how it moves — container, LCL, air — and what you sell. Within one business day you'll have receiving instructions to hand your forwarder plus a per-unit rate sheet for everything that happens after the handoff.
