Amazon FBM (Fulfilled by Merchant)

In the FBM model the seller stores inventory, packs and ships each order, and handles customer support instead of using Amazon’s fulfillment network.

How FBM Works

You list products on Amazon, manage stock in your own warehouse or 3PL, buy postage, upload tracking, and meet Amazon’s service-level targets.

Pros and Cons

Pros: lower fees, full control over packaging, easier oversized or hazmat handling.
Cons: no Prime badge, stricter performance metrics, higher shipping workload.

Key Performance Metrics

Order defect rate < 1 %, late shipment rate < 4 % and valid tracking rate ≥ 95 % per Amazon policy. Set SellerSonar alerts to catch breaches early.

FBM vs FBA

FBM can beat FBA on heavy items or when you own fast local delivery. Compare landed cost and Buy Box share in the SellerSonar dashboard.
