An Amazon FBA Prep Center is a company that prepares your items to be sent to Amazon FBA warehouses for you.

There are services for every type of sourcing strategy – arbitrage, wholesale, private label, etc. Rather than sending inventory to your home or warehouse, you send it to your prep centers address. The prep center then receives your shipment for you, inspects the products, and then does the necessary prep to send the items to FBA warehouses.
