I would like to setup a Shopify storefront (let's call it "ACME Online Store") to enable customers to purchase products from a number of suppliers/wholesalers/merchants (who also have their own Shopify storefronts). All orders will be fulfilled (delivered) by those merchants, too. Yes, the customer will typically receive multiple deliveries.
Do I need to create a custom Sales Channel app/platform to enable my Suppliers/Merchants to add their products to my online store? Am I missing anything?
