The concept of these apps is to own a market in the app (Vendor), Upload your available products for sale as the vendor, Registered users can purchase the products by cash, card or bank which is decided by the owner of the app (Admin). The products are either delivered by a delivery boy base on the delivery fee or can be picked up by the registered user. A monthly subscription is made to the app owner by the admin as an agreement between them.
