A WORKED EXAMPLE

Seller-managed can still use a 3PL.

A seller routes its FBM orders to a 3PL. The partner picks, packs and hands parcels to carriers, while the seller remains responsible for meeting applicable marketplace requirements. The use of a warehouse partner does not turn those orders into FBA.
