Sometimes you might want to make your website only available to registered members. By introducing a paid membership, you can offer lower prices for your items but make money on subscription fees. Buyers will be aware of the low prices and pay for the privilege to have access to those deals. Sellers will also be able to sell their items knowing that a community of buyers are available – this is typically useful for getting rid of old/unwanted stock or selling in bulk.
To create a private marketplace you need to make sure only “Email verified users” and Browse listings. This will make your home page show only the registration screen. Nobody will be able to browse your marketplace without registering.
You can further restrict your marketplace to make sure only users subscribed to a plan or identity verified users can post listings or place orders.
