what are fulfillment centers are specialized facilities where products are stored, picked, packed, and shipped to customers. Fulfillment centers play a crucial role in the e-commerce supply chain by ensuring timely delivery of orders. These centers may be operated by third-party logistics (3PL) providers or in-house by businesses. Fulfillment centers help businesses streamline their operations by handling inventory management, order fulfillment, and sometimes returns processing. Many e-commerce platforms use fulfillment centers to scale their operations and meet customer demand more effectively.
