EQuili is an innovative e-commerce platform that enables customers to purchase products at a lower price than the market price by conducting an auction between suppliers. The system allows you to select a product from a wide range of products as well as to determine the target price. The price which the customer wants to pay for the product. Upon selection, the system will send notifications to the relevant suppliers and the first to confirm the requirement will deliver the product to the customer. In addition, a trade-in plug-in is developed, which enables embedded commerce site owners to embed the eQuili system on both the client/user interface and the management interface.
