The two types of merchant-fulfilled operations that you can choose to be a part of as a seller using the Amazon FBM program are the standard Fulfillment by Merchant option or Seller Fulfilled Prime.
Fulfillment by Merchant, or FBM as it is most commonly known, is a fulfillment method in which an Amazon seller is responsible for fulfilling their products purchased on Amazon. Amazon FBM is managed through a seller directly or by using a third-party logistics (3PL) provider.
Seller Fulfilled Prime allows you to benefit from the coveted Amazon Prime badge, as long as you adhere to the requirements for qualifying as an SFP seller. This option allows you to deliver directly to domestic Prime customers from your own warehouse. By displaying the Prime badge, you are committing to fulfill orders with Two-Day Delivery at no additional charge for Prime customers. Amazon gives you access to the right transportation solutions to help you meet the high bar for the Prime customer experience.
