Marketplace Prep
Your inventory, ready for
FBA and Mercado Libre Full.
We prep your product per each marketplace's official specs: FNSKU, polybag, expirables, oversize, and bundling. Direct shipment to Amazon and Mercado Libre centers — from Guadalajara, without your team wrestling with prep manuals that change every quarter.
- FBA · Mercado Libre Full
- FNSKU + compliant polybag
- FEFO on expirables
What's included
Your product enters the marketplace, not the rejections team
Six elements that separate a shipment that enters and sells from one that returns with non-compliance fees.
Official FBA prep
FNSKU labels, polybag with suffocation warning, Amazon prep types. We meet the official manual, not approximations.
Mercado Libre Full
Full labels, compliant packaging, and shipment to the closest Full center. SKU onboarding from scratch if not yet enrolled.
Walmart Connect & others
Also Liverpool Pago en Línea, Coppel, and other local marketplaces with their own specs.
FEFO on expirables
For supplements, food, and cosmetics: rotation by expiration date. Your product doesn't expire in FBA's warehouse.
Bundling and multipack
Combos, packs of 2/3, promotional sets with unique FNSKU. No hidden fees on composite SKU.
Cross-border to FBA US
For brands selling into the U.S.: consolidation, FBA labeling, and shipment to the Amazon center on U.S. soil.

Why Ecommex
Marketplaces don't forgive the detail
Three reasons brands with active FBA and MeLi Full prefer to outsource prep.
01
Real specs
We track the updated manuals
FBA changes prep types and polybag specs every quarter. We're subscribed to official updates — your team shouldn't be reading 80-page PDFs.
02
Volume
Hot Sale, Buen Fin, and Prime Day peaks without collapse
Scalable capacity for peaks where marketplace prep doubles or triples. Without delaying your inbound shipment.
03
Multi-marketplace
One warehouse, every channel
FBA, Mercado Libre Full, Walmart Connect, your D2C. You don't replicate inventory per marketplace — we allocate by real rotation.
$0.30+ USD
Is what Amazon FBA charges per unit if your product arrives without proper labeling.
Between $0.30 and $1.50 USD per unit for re-labeling or re-packaging that Amazon performs at its center when your shipment doesn't meet specs. On a 5,000-unit inbound, that's $1,500 to $7,500 USD out of your margin — not counting the risk of temporary shipment block, seller account suspension, or Buy Box loss while it's resolved.

Amazon FBA (Mexico, US, Canada), Mercado Libre Full (Mexico), Walmart Connect, Liverpool Pago en Línea, Coppel, and other local marketplaces. If you sell on one we don't list, we evaluate its specs and tell you if it fits.
