FBA vs FBM: which fulfillment wins for your product?
FBA hands the operation to Amazon and charges flat per-unit fees. FBM keeps you in control of packing and shipping. The right answer depends on weight, margin and sales predictability.
| Factor | FBA | FBM |
|---|---|---|
| Per-unit cost | Flat 2026 fulfillment fee + storage | Your own shipping rate, no storage fee |
| Prime eligibility | Automatic | Only via Seller Fulfilled Prime |
| Best for | Light, fast-moving SKUs | Heavy, slow-moving, oversize items |
| 2026 fee exposure | Placement, LIL and aged surcharge apply | None of the new FBA-only fees apply |
