Fulfillment options refer to the various methods businesses use to deliver products to customers after an order is placed. Common options include in-house fulfillment, where a company manages its own inventory and shipping, and third-party logistics (3PL), where an external provider handles storage, packing, and shipping. Another popular option is drop shipping, where the retailer sells products without holding inventory, instead relying on suppliers to ship directly to customers. Each fulfillment option has its own advantages and challenges, impacting factors like cost, speed, and customer satisfaction.
