What sellers should know.
This page is written for ecommerce teams that need clear decisions, not surface-level definitions.
FBM gives control on bulky or margin-sensitive SKUs, but delivery speed and Buy Box impact must be watched.
The right model can differ by SKU, season and event calendar. High-velocity hero SKUs may deserve FBA while slow movers stay FBM.
Apex compares FBA/FBM through CM2, stock cover, delivery promise and return impact.
