West Coast Amazon FBA Prep and FBM

Inventory Prepped to Amazon's Requirements

Selling on Amazon means getting products ready for the right fulfillment process. FBA inventory must be prepared and shipped to Amazon’s fulfillment network, while FBM orders need to be picked, packed and shipped to customers by the seller or its fulfillment partner.
