what is the fulfillment center A fulfillment center is a third-party service provider that handles the storage, packing, and shipping of products for e-commerce businesses. When a customer places an order, the fulfillment center picks and packs the product, then ships it directly to the customer’s address. Fulfillment centers are often used by businesses to streamline their logistics operations, allowing them to focus on marketing and product development while the center takes care of the warehousing and shipping processes. They help reduce overhead costs and improve delivery times.
