Comparison
FBA vs FBM
Amazon fulfilled by Amazon vs fulfilled by merchant - which one actually fits your catalog.
The FBA-vs-FBM decision isn't one-size-fits-all - it depends on your margins, SKU velocity, and how much control you need over the customer experience. Both can win the Buy Box; the tradeoffs show up in cost structure and operational load, not visibility.
FBA (Fulfilled by Amazon)
Amazon stores, picks, packs and ships the order for you.
- Prime eligibility and faster delivery windows, which measurably help conversion
- Amazon handles customer service and returns for the order itself
- Storage and fulfillment fees scale with size and how long inventory sits
- Less control over packaging, and inventory placement fees can spike in peak season
FBM (Fulfilled by Merchant)
You or your 3PL store, pick, pack and ship the order.
- Full control over packaging, inserts and the unboxing experience
- No FBA storage or fulfillment fees - cost structure is whatever your own fulfillment costs
- You're on the hook for shipping speed, and Prime badge access is limited without Seller Fulfilled Prime
- You own customer service and returns, which is more work but more data
Which one fits
High-velocity, low-margin SKUs generally do better on FBA - the Prime badge moves enough volume to absorb the fees. Bulky, slow-moving, or high-margin catalogs often do better on FBM, where fulfillment cost control matters more than delivery speed. Many of the catalogs we manage run a hybrid split by SKU rather than picking one model for the whole account.

Frequently asked questions
Yes - Amazon supports mixed fulfillment on the same catalog (and even the same ASIN via Seller Fulfilled Prime), so you don't have to pick one model account-wide.
It can, since Amazon's Buy Box algorithm favors Prime-eligible offers. FBM listings can still win it, but you typically need Seller Fulfilled Prime or a strong price/performance edge to compete evenly.
