Amazon FBA & Walmart WFS Prep Center
An Illinois-based FBA prep service and 3PL for Amazon and Walmart sellers. FNSKU labeling, poly bagging, bundling, and carton prep, all 100% compliant and shipped in 24 to 72 hours. Trusted by brands since 2017.
Who we are
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
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
Printed directly through Amazon's API. Accurate, scannable, compliant every time.
From suffocation-warning poly bags to industrial shrink wrap, all to Amazon spec.
Multipacks and multi-SKU kits built into a retail-ready product you are proud to ship.
Full Walmart Fulfillment Services prep and compliance alongside your Amazon inventory.
We forward your master cartons to Amazon on your schedule, so you replenish without lifting a box.
FBA removal orders and individual returns handled for anything shipped from our warehouse.
How it works
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 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.
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
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.
