Choose by product and order profile. FBA uses Amazon’s fulfillment service; FBM leaves fulfillment with you or your appointed operation. A hybrid can use both for different parts of the catalog.
Compare the operating choices
| Model | What to evaluate |
|---|---|
| FBA | Program eligibility, inbound prep, inventory placement, storage and fulfillment fees. |
| FBM | Your handling time, stock control, packing, carrier services, tracking and returns responsibilities. |
| Hybrid | Which SKUs use each route, how stock is allocated and how replenishment is planned. |
Calculate the full cost with current program information and your actual dimensions, weights, sales patterns and handling needs. An old fee example or generic percentage will not establish the right choice.
Review the customer promise
Merchant-fulfilled delivery settings need to match the operation that will ship the order. Prime eligibility is a separate Amazon program; choosing a 3PL does not automatically award a badge. Use Amazon’s current guidance for account-specific requirements.
Test stock and exceptions
- Which system controls merchant-fulfilled availability?
- How will replenishment stock be separated from direct customer orders?
- What happens to cancellations, partial orders and returns?
- Which provider owns each preparation, label and tracking step?
