A sort of Amazon seller known as an FBA (Fulfillment by Amazon) seller makes use of Amazon's fulfillment network to store, package, and send their goods to buyers. When an order for a product from an FBA seller is placed on Amazon, Amazon handles the shipment and handling of the product. FBA sellers send their inventory to Amazon's fulfillment centers.

FBA Sellers profit from Amazon's extensive fulfillment network, which enables them to provide customers with Prime delivery alternatives and profit from Amazon's return and customer service policies. Furthermore, rather than stressing about the difficulties of shipping and managing orders, FBA Sellers may concentrate on product sourcing and marketing.

FBA Sellers pay Amazon fees for storage, handling, and fulfillment in exchange for these services; which differ according to the dimensions and weight of their products as well as how long they are kept in Amazon's warehouses.
