Wholesale solution for retailers (membershipsplans and recurring subscriptions)

Im building in this days a dropshipping site which will offer a range of products in different categories. I also want to make either this as a multisite or copy my existing to a new domain where my aim is to offer dropshipping package for businesses. (Other shops buy from me and i ship products to the shop or directly ti their customer). I would appreciate as simple solution as possible but needs to be proffesional. Im picturing a membership solution with resticted acess according to their subscription plan (user role). I will also add csv files in woocommerce for download on each categories. in your offer please state how this solution is build up. For questions please chat with me,
