FBA stands for “Fulfillment by Amazon.” It’s a service provided by Amazon where they handle the storage, packaging, and shipping of products for sellers. When sellers use FBA, they send their products to Amazon’s fulfillment centers, and when a customer buys their product, Amazon takes care of sending it out. This service also includes handling customer service and returns for these orders. It’s a popular option for many sellers on Amazon because it can save them time and effort in managing the logistics of their sales.
