Like many big box retailers, sellers can apply to become approved suppliers to Walmart for drop shipping. This means that Walmart will buy products from merchants and market them online at Walmart.com. Orders will be forwarded to the merchant. The merchant then ships it to the customer with a Walmart packing slip.
Please note: This Walmart program is separate from Walmart Marketplace where sellers market directly on Walmart.com. SellerCloud supports Walmart Marketplace. Read more about that here.
SellerCloud integrates through the Walmart DSV API to directly connect to the channel. There is no testing process and no third-party integrator necessary.
You can set your products up with the correct price so that the orders will import with the amount you are getting for each sale, making it easy to export the order data into QuickBooks and create invoices. You don't need to actually send them the invoice, because SellerCloud will automatically invoice Walmart for each order.
