warehouse and fulfillment refer to the combined logistics process of storing inventory and shipping it to customers. A fulfillment center acts as a third-party logistics provider (3PL) that handles order processing, packing, and delivery. These services are essential for e-commerce brands looking to scale without managing physical inventory. Warehouses focus more on long-term storage, while fulfillment centers emphasize fast turnover and efficient shipping. Choosing the right warehouse and fulfillment partner impacts cost, customer satisfaction, and delivery speed.
