FBA vs FBM: How to Tell How an Amazon Product Ships
FBA vs FBM explained: how to tell from the product page whether an offer is Fulfilled by Amazon, shipped by the seller or sold by Amazon, and why it matters.
To tell whether an Amazon offer is FBA or FBM, read the two lines in the buy box. Ships from Amazon and Sold by another seller means FBA (Fulfilled by Amazon): Amazon stores and ships the item. Ships from and Sold by the same seller means FBM (Fulfilled by Merchant): the seller ships it. If both lines say Amazon, Amazon sells the product itself.
What FBA and FBM mean
- FBA, Fulfilled by Amazon: the seller sends stock to Amazon’s warehouses. Amazon stores it, packs and ships orders, and handles customer service and returns. The seller pays Amazon’s fulfillment and storage fees.
- FBM, Fulfilled by Merchant: the seller keeps the stock and ships each order itself or through its own logistics partner.
- Sold by Amazon: Amazon buys the product and sells it itself. This is not a third-party offer.
How to check FBA or FBM on a product page
- Open the product page.
- In the buy box, find Ships from and Sold by.
- Compare them:
| Ships from | Sold by | Fulfillment |
|---|---|---|
| Amazon | A seller | FBA |
| A seller | The same seller | FBM |
| Amazon | Amazon | Sold by Amazon |
This shows the fulfillment of the featured offer only (what the Buy Box is).
How to check the other offers
Open Other sellers on Amazon or See all buying options. Each offer in the list has its own Ships from and Sold by lines, so you can count how many offers are FBA and how many are FBM (how to find who sells a product).
What about the Prime badge?
Prime offers are usually FBA, but not always: with Seller Fulfilled Prime, a seller ships Prime orders itself. The Ships from line is the reliable check.
FBA vs FBM: the differences
| FBA | FBM | |
|---|---|---|
| Who stores and ships | Amazon | The seller |
| Prime | Usually yes | Only with Seller Fulfilled Prime |
| Customer service | Amazon | The seller |
| Fees | Amazon fulfillment and storage fees | The seller’s own shipping and storage costs |
| Control over stock | Less: stock sits in Amazon’s warehouses | Full |
Neither is better for every product. FBA often suits small, fast-selling items; FBM can suit large, heavy or slow-selling items, where storage fees add up.
Why it matters in product research
- Competition: FBA offers usually deliver fast and qualify for Prime, so they often win the Featured Offer. If a product’s offers are mostly FBA, an FBM offer has to match their delivery.
- Amazon as a seller: if Amazon ships and sells the product itself, it often holds the Featured Offer.
- Your own costs: whether you plan FBA or FBM changes your margin. Check Amazon’s fees for both before you decide.

FAQ
What does “Ships from Amazon, Sold by” another seller mean?
The offer is FBA. Amazon stores, packs and ships the item, but the seller owns the offer and sets the price.
Can one product have both FBA and FBM offers?
Yes. Every seller of the same product chooses its own fulfillment, so the offer list often mixes FBA and FBM.
Is Prime the same as FBA?
No. Most Prime offers are FBA, but sellers can also ship Prime orders themselves with Seller Fulfilled Prime.
Do FBA offers always win the Buy Box?
No. FBA helps through fast delivery, but price, stock and seller performance also count.
Which is better, FBA or FBM?
It depends on the product. Compare Amazon’s FBA fees with your own shipping and storage costs, and look at how the other sellers of the product fulfil it.
