How Amazon Fulfilled by Merchant businesses operate when the seller controls storage, packing, shipping and much of the fulfillment workflow.
Profile updated
Amazon FBM uses Amazon as a marketplace while keeping fulfillment responsibility with the seller or the seller’s logistics provider. Compared with FBA, that can provide more control over inventory placement and shipping, but it makes warehouse, carrier and service performance part of the core operating risk.
What is Amazon FBM?
Fulfilled by Merchant (FBM) means the merchant lists products on Amazon while fulfilling orders outside Amazon’s FBA network. The seller stores or arranges storage for inventory, packs orders, ships them and manages the service obligations associated with merchant fulfillment. A business may use FBM for all products or operate a hybrid FBA/FBM strategy.
Example: How this business works
Suppose a company sells replacement air filters through Amazon but fulfills the orders itself. The business buys filters in bulk and stores them in a warehouse or third-party logistics facility. A customer orders on Amazon. The seller’s warehouse or logistics partner picks, packs and ships the order and provides tracking.
Amazon provides the marketplace and order, but the seller is responsible for fulfillment performance. The owner manages inventory, warehouse or 3PL performance, carriers, returns, advertising and account health.
Major costs include product, warehousing, labor, packaging, shipping, Amazon referral fees, advertising and returns. Profit exists when product margin covers both marketplace costs and the seller-controlled logistics operation.

How money moves through the business
Orders originate on Amazon, but the seller’s own warehouse, staff, 3PL or other fulfillment arrangement executes delivery. The operator must maintain inventory accuracy, meet Amazon shipping and performance expectations, manage returns and customer issues, and coordinate carriers. The economic comparison with FBA depends on product dimensions, volume, storage, shipping zones and operational capability.
Revenue comes primarily from product sales on Amazon. Profit reflects product cost, Amazon referral fees, storage, warehouse or 3PL expense, packaging, shipping, labor, advertising, refunds/returns, software and overhead.
What does the owner actually do?
Ongoing: monitor order exceptions, late shipments, returns, inventory and account metrics.
Regularly: manage warehouse or 3PL performance, carriers, replenishment, advertising and customer-service issues.
Monthly: reconcile true fulfillment cost per order and review product contribution margins.
Periodically: renegotiate shipping or 3PL contracts, change facilities or respond to account-performance problems.
What are you actually buying?
An FBM acquisition may include the brand and intellectual property, product catalog, inventory, Amazon listing history, supplier relationships, warehouse or 3PL arrangements, carrier relationships, advertising history and operating procedures.
Confirm how seller-account continuity will be handled, whether inventory is included and whether warehouse, carrier and logistics agreements can continue on acceptable terms.
Economics to understand
FBM replaces some FBA fees with seller-controlled logistics costs; it does not eliminate fulfillment cost.
Warehouse rent or 3PL fees.
Fulfillment labor and management.
Packaging and shipping labels.
Parcel/carrier charges and surcharges.
Cost of goods and inbound freight.
Amazon referral fees and advertising.
Returns, reships and customer-service costs.
Inventory systems and operational software.

Metrics worth watching
Fulfillment cost per order.
On-time shipment/tracking and cancellation performance.
Return/reship rate.
Shipping cost as a percentage of revenue.
Inventory accuracy and turnover.
Top-SKU and supplier concentration.
Warehouse/3PL concentration.
Contribution margin after shipping and Amazon fees.
Potential advantages
More direct control over inventory storage and fulfillment processes.
Can be economically suitable for products or circumstances where FBA is not preferred.
May support hybrid channel fulfillment from one inventory pool.
A strong 3PL relationship can separate the owner from daily warehouse work.
What can go wrong
Fulfillment performance is directly the seller’s responsibility.
Warehouse or 3PL dependency becomes a material acquisition issue.
Shipping-cost inflation can compress margins.
More operational labor and exception handling may be required than an FBA model.
Seller-performance failures can affect the Amazon account.
FBM diligence needs both Amazon-account review and logistics diligence.
Late shipment, cancellation or tracking-performance issues.
Concentration in one warehouse, 3PL or carrier.
High shipping cost for bulky or geographically dispersed orders.
Inventory mismatches between Amazon and physical stock.
Labor dependency in an owner-operated warehouse.
Supplier/SKU concentration and working-capital exposure.
Amazon account or listing compliance risk.
Buyer diligence questions

What are the true shipping and fulfillment costs by product and destination?
How often have late shipment, cancellation or tracking metrics caused account issues?
How much inventory is included and where is it physically held?
Could the current warehouse or 3PL relationship continue after closing?
How concentrated are profit and inventory in the largest products and suppliers?
