Amazon fulfillment models

Fulfilled by Merchant: Fulfilled By Merchant (FBM) is when you list your products on Amazon and choose to ship products to each buyer by yourself. In other words, you’re responsible for fulfilling the orders and do not rely on Amazon for the same. While it is a rather advantageous method for products with lower margins. You need to find shipping partners who are reliable and cost-effective.
Fulfillment by Amazon: Fulfillment By Amazon (FBA) is a service provided by Amazon that provides storage, packaging, and shipping assistance to you. This takes the burden off and grants you more flexibility in your selling practices. The program allows you to ship your products to an Amazon fulfillment center, where products are stored in warehouses until they are sold. When an order is placed, Amazon prepares, pack, and ships the product.
