order fulfillment online refers to the process of receiving, packaging, and shipping orders placed through e-commerce platforms like Amazon. Sellers may choose self-fulfillment or third-party services such as Fulfillment by Amazon (FBA) to manage logistics. Online fulfillment is a key part of the customer experience, directly affecting delivery times and satisfaction. Efficient fulfillment solutions improve store ratings, reduce returns, and free up time for sellers to focus on scaling their business operations.
