Amazon FBM is undoubtedly an incredible platform for listing your items; everything else is up to you. So, to begin with Amazon FBM, you must do the following:
Create an Amazon account. Add your products to Amazon. Keep your stock. Orders should be packaged and shipped. Handle all queries of customers either directly or through a 3rd party.
It’s not a big deal, and FBM listings are made the same way as standard . So you can choose the option: ‘I will ship the item myself’ inside the Fulfilment Channel section (Merchant Fulfilment).
