FBM (Fulfilled by Merchant)

Amazon FBM is a fulfillment method where sellers store, pack, and ship products directly to customers. Sellers are responsible for inventory, shipping, returns, and customer service.

What is Amazon FBM?

Fulfilled by Merchant (FBM) is an Amazon fulfillment option where the seller handles the entire order fulfillment process. This includes storing inventory, packing orders, shipping products, and managing customer service and returns.

Advantages and Challenges of FBM

  • More control over inventory and shipping processes
  • Lower fees compared to FBA for certain product categories
  • Flexibility in using custom packaging and carriers
  • Requires strong logistics and fast shipping capabilities
  • Higher risk of losing the Buy Box without competitive delivery speeds

FBM and Buy Box Eligibility

FBM sellers can win the Buy Box, but it requires excellent seller performance, competitive pricing, and reliable shipping. Delays, cancellations, or negative feedback can quickly impact Buy Box eligibility for FBM offers.
