What is FBM?
Fulfillment by Merchant — when sellers handle storage, packing, and shipping themselves instead of using Amazon FBA.
Definition
FBM stands for Fulfillment by Merchant, also known as Merchant Fulfilled Network (MFN). Under this model, the seller is responsible for storing inventory, packing orders, shipping products to customers, and handling returns and customer service. Unlike FBA where Amazon handles logistics, FBM sellers manage the entire fulfillment process from their own warehouse, home, or third-party logistics provider. FBM products do not automatically qualify for Amazon Prime, although sellers can apply for Seller Fulfilled Prime (SFP) if they meet Amazon's strict delivery performance requirements. FBM is often preferred by sellers with oversized or heavy products where FBA fees would be prohibitively expensive, sellers with existing warehouse infrastructure, and sellers who want more control over their fulfillment process. Many successful Amazon sellers use a hybrid approach, fulfilling some products via FBA and others via FBM based on which method maximizes profitability for each specific product.
How FBM Relates to E-Commerce
FBM plays an important role in e-commerce strategy, particularly for sellers dealing with large, heavy, or low-margin products where FBA fees would eliminate profitability. It also provides a backup fulfillment method during peak seasons when FBA warehouses may have receiving limits. FBM sellers have more control over packaging, branding, and the customer unboxing experience. For dropshipping and print-on-demand business models, FBM is the standard fulfillment method since products ship directly from the supplier or print facility. Understanding when to use FBM versus FBA is a key strategic decision that impacts profitability, Buy Box eligibility, and customer satisfaction.
