What Is Amazon FBA?
Fulfillment by Amazon (FBA) is a service where Amazon stores, packs, ships, and manages customer service for your products. You send your inventory to Amazon’s fulfillment centers, and they handle the rest.
This convenience helps in running an e-commerce business without catering to warehousing and shipping. Yet, this ease of use involves costs, specifically FBA fees.
