What is Fulfillment in Ecommerce? Fulfillment in e-commerce refers to the process of storing, packing, and shipping products to customers. This process includes receiving orders, picking products from inventory, packaging them, and shipping them to the customer. Fulfillment can be managed in-house, by third-party logistics (3PL) providers, or through services like Fulfillment by Amazon (FBA), where Amazon handles the entire fulfillment process. Efficient fulfillment is crucial for providing customers with fast delivery and maintaining a smooth operation for e-commerce businesses.
