The Amazon Model
The Multi-vendor Marketplace
There are numerous multi-vendor marketplace models that you may be interested in. The first is similar to eBay, Etsy or Amazon, where each person selling items can sign up for their "own store" which really just adds their products in with all the other products, to make them available to the site search and product comparison. After that, a user can favorite your store, communicate with you via the "Ask a Seller a Question" feature, click on your store name and filter the store to only show products that you offer, and finally not only rate your products, but rate you as a seller.
Another multi-vendor marketplace platform use is the franchise multi-store model. One implementation like this of ours is New Horizons Computer Learning Centers franchise multi-store. This model allows each franchise to have their own URL / storefront, yet be "connected" to the franchise or franchise group. This hierarchy allows the Corporate franchise to share products, content, and pricing with the franchises, yet allows each franchise to accept, reject or translate that information before posting to their own sites. It can also allow each franchise store to localize content, set their own pricing, graphics, messaging and more. We were able to design 3 skins that each franchise could choose from, setup their own tokenized contact information, payment gateway options, and whether content sent from corporate was to be published, re-priced, localized or more. This model was rolled out to 350+ sites/storefronts in more than 70 countries, offering checkout in over 200 currencies.
