Amazon FBA
Learn the definition of Amazon FBA (Fulfillment by Amazon). Discover how the process works, the costs involved, and the pros and cons.
Amazon FBA (Fulfillment by Amazon) is a service where sellers send inventory to Amazon, and Amazon stores, packs, ships orders, and handles customer service. It enables Prime shipping while allowing sellers to focus on product sourcing and growth.
What is Amazon FBA?
FBA is a service where sellers outsource their entire logistics operation to Amazon. In simplest terms: You sell it, Amazon ships it.
The Concept: You send your products to Amazon's fulfillment centers.
The Service: Amazon handles storage, picking, packing, shipping, customer service, and returns.
The Result: Your products become eligible for Prime benefits, such as fast, free shipping, which can significantly boost sales and allow you to focus on sourcing and marketing rather than taping boxes.
How does the FBA process work step-by-step?
The process functions on a clear loop between you and the fulfillment network:
Send Inventory: You ship your products in bulk to Amazon's warehouses.
Amazon Stores: Your products are cataloged and stored in fulfillment centers.
Customer Orders: When a shopper buys your item, Amazon’s system is triggered.
Pick, Pack, & Ship: Amazon locates the item, packs it in Amazon-branded boxes, and ships it to the customer.
Customer Support: The platform handles inquiries, tracking, and returns for the order.
What are the advantages of FBA?
Advantages of Amazon FBA are -
Prime eligibility with fast, trusted shipping
Higher Buy Box win rates and conversion rates
Amazon handles storage, packing, shipping, returns, and customer support
Easy scalability without managing your own logistics
Improved customer trust through Amazon fulfillment
What are the main disadvantages and common mistakes?
While powerful, FBA has downsides:
Costs: Fees can erode margins if not calculated correctly. Long-term storage fees apply to unsold stock (over 180 days).
Loss of Control: You cannot use custom-branded boxes, and Amazon controls the return process (sometimes refunding items you might not deem returnable).
Common Mistakes: Miscalculating profit margins, ignoring storage limits, and failing to account for "aged inventory" surcharges.

FBA Pan-EU / Global Selling: Allows you to store goods in international fulfillment centers to reach global customers.
Multi-Channel Fulfillment (MCF): Amazon fulfills orders sold on other platforms (like your own website or Shopify) using your FBA stock.
How much does Amazon FBA cost?
It uses a pay-as-you-go model with several fee structures:
Referral Fees: A commission paid on every sale (typically around 15% depending on category).
Fulfillment Fees: Covers picking, packing, shipping, and service; based on unit weight and dimensions.
Storage Fees: Charged monthly based on the volume (cubic feet) your inventory occupies.
Closing Fees: A variable fee often applied to media items (books, DVDs) or specific categories.
Is FBA the same as dropshipping?No.
