US based client wanted us to build a website for 3 types of user.
On this website buyers can offer a promo codes to sellers and sellers can use them to buy the listed services/products.
We have developed a backend panel for admin of the site that can manage buyers and sellers. Website has been developed in PHP and MySql. We have integrated Facebook API in this site as well.
