FBA stands for Fulfillment by Amazon, a service that provides storage, packaging, and shipping support to product sellers on Amazon. An FBA seller is an online retailer that uses Amazon's store to sell its products and delegates inventory control to Amazon through the FBA program. By using FBA, Amazon marketplace sellers can focus more on marketing and customer interaction, giving them more flexibility and freeing up time to manage other elements of their businesses.

The benefits of Amazon Fulfillment are as follows:

• Firstly, using the storage and shipping services provided by FBA can save you a lot of time and money. 
• Compared to any other shipping operation you could put together in a similar amount of time, shipping products through FBA will likely be faster and more reliable.
• In addition, FBA shipping allows you to offer free shipping to your customers, making your products more appealing. With the low cost of FBA, you can increase your popularity and rating on Amazon, resulting in higher sales rankings and more customers than ever for your high-quality products.
