Core Viewpoint - Amazon is changing its seller payment settlement method from "payment upon shipment" to "delivery date + 7 days" (DD+7) starting March 12, 2026, which significantly extends the cash flow cycle for sellers [1][2]. Group 1: Policy Change Impact - The new DD+7 model requires sellers to wait until 7 days after the buyer confirms receipt of the product before funds are available, directly increasing cash flow pressure on sellers, especially those with longer logistics times or limited cash flow [2][3]. - To alleviate cash flow pressure, sellers must focus on quick order response and logistics efficiency, as faster delivery will trigger the "+7" countdown sooner, accelerating cash recovery [2][3]. Group 2: Logistics Solutions - The company "开仓了" has established a self-operated warehouse network covering key areas in the U.S., ensuring that most orders are shipped from the nearest warehouse, thus reducing delivery time and enhancing cash flow recovery [3][5]. - The self-developed intelligent warehousing system optimizes inventory distribution based on historical sales data and buyer address distribution, allowing sellers to pre-position stock in various warehouses for efficient delivery [5][8]. - The company ensures that goods are shelved within 24 hours of arrival and that orders are picked, packed, and shipped within 24 hours, with packages entering the delivery network within 48 hours, maximizing delivery speed [5][8]. Group 3: Competitive Advantages - The company leverages strong local resources in the U.S. to secure advantageous last-mile delivery accounts, ensuring stable capacity even during peak sales seasons, thus preventing delivery delays [7][8]. - The combination of the intelligent system and the self-operated warehouse network creates an efficient logistics system that accelerates the delivery process and shortens the cash recovery cycle for sellers [8].
