A reverse-marketplace is where instead of sellers uploading the products that they wish to sell on a market platform, it is the buyers who create detailed requests (posts) for products they wish to buy, with sellers (exhibitors) then proposing offers based on their inventories that match the open-call inquires.

Within the Postbys platform, a reverse-marketplace is created for each tradeshow before its start and lasts until the end of the event.

This is the most optimal way to centralize all purchasing requests and provide targeted matchmaking between buyers and sellers at individual tradeshows, which ultimately helps increase sales for exhibitors using Postbys.
