A trade (category) classifies acceptor businesses and marketplace products — e.g. “Restaurant”, “Apparel”, “Auto services”. Without trades, members cannot browse discounts logically and the marketplace cannot organize catalog items. Each trade may define commission rate, suggested discount, and rules such as “merchant products allowed”.
Platform admins build the full trade tree and link work groups. Club managers view and search — seeing platform-wide and club-specific trades — and attach them when approving acceptors. Merchants see their active trades and can request additional categories.
Daily flow: admin defines trade → club links acceptor → merchant requests new trade if needed → club approves on acceptor detail page.
