Amazon FBA vs FBM in 2026: how to choose (or run both)

The FBA vs FBM tradeoff

FBA gives you Prime badge, faster delivery, and Amazon-handled returns. The cost: 15–20% of revenue in FBA fees, lost margin on each oversized SKU, and zero control of inventory location. FBM keeps inventory in your warehouse, lower fees, and SKU flexibility — but you fight for the Buy Box and you ship every order yourself.

Run both — the hybrid play

Most growing brands run hybrid: top sellers on FBA for Prime velocity, slow movers and oversize SKUs on FBM through a 3PL. The split keeps FBA inventory healthy and protects margin on long-tail. Operating both is feasible with one connector (e.g., ShipStation or our WMS) routing orders to the right system.
