Who we are
Let us handle prep, so you can focus on growing your brand.
You should not be buying boxes, printing labels, or racing Amazon's inbound deadlines. That is our job, and we love it. We turn your incoming inventory into shelf-ready, 100% compliant shipments so your listings stay in stock and your account stays in good standing. Same building, same team, same standards, since 2017.
Hands-off prep
Run your Amazon business from anywhere in the world.
Purchase. That is all you have to do. Buy your inventory, have your supplier ship it to us, and AMSCO Prep handles the rest: receiving, inspection, FNSKU labeling, prep, and inbound to Amazon. Quickly. Efficiently.
What we prep
Everything your inventory needs before Amazon.
FNSKU Labeling
Printed directly through Amazon's API. Accurate, scannable, compliant every time.
Poly Bagging & Shrink Wrap
From suffocation-warning poly bags to industrial shrink wrap, all to Amazon spec.
Bundling & Kitting
Multipacks and multi-SKU kits built into a retail-ready product you are proud to ship.
Walmart WFS Prep
Full Walmart Fulfillment Services prep and compliance alongside your Amazon inventory.
Case & Carton Forwarding
We forward your master cartons to Amazon on your schedule, so you replenish without lifting a box.
Removals & Returns
FBA removal orders and individual returns handled for anything shipped from our warehouse.
How it works
You ship. We prep. Amazon receives.
You Ship
Open your prep account and send inventory to our Huntley, IL warehouse. Log each inbound shipment in the portal so we check it in fast.
We Prep
We receive, inspect, and prep every unit: labeling, bagging, bundling, and carton prep. We build your shipment plans and notify carriers. You stay 100% hands-off.
We Ship In
Compliant inventory is staged and inbounded to Amazon on your schedule, with a paid invoice and full visibility the whole way.
Built into the price
Some of the lowest storage rates in prep.
At $1.00 a day per pallet, our storage comes in below most prep centers. Flat per-pallet pricing means you keep the savings when you pack a slot efficiently, instead of paying for airspace. Inventory that is actively in process is never charged storage, only what sits. Fast 24 to 72 hour turnaround keeps your inventory moving, not sitting.
AMSCO Prep is a verified member of the Amazon Solution Provider Network. When Amazon stopped prepping inside its fulfillment centers, a compliant prep partner became essential, and we are vetted for exactly that.
