This Guidance demonstrates how retailers can onboard new suppliers and process orders of these suppliers’ products to help them provide customers with more product choices without higher inventory cost. It is designed for retailers who want to offer a wide range of products to their customers, but can’t always take on the cost of holding the inventory. For many retailers, creating an online marketplace for third-party sellers addresses this problem and creates an additional revenue stream through listing fees. With this Guidance, retailers can implement the marketplace software that allows them to quickly recruit and onboard new sellers and list their products alongside their own, offering their customers more choice. When these new products are ordered, the order is routed to the seller for fulfillment and the retailer collects their fee.
