Walmart is one of the largest retailers in the world with approximately 10,500 stores and clubs under 46 banners in 24 countries and eCommerce websites offering more than a million products to people. In order to bring that number of products onto the shelves and makes them accessible for everyone, Walmart offers an EDI (electronic data interchange) process for all its vendors, suppliers, and distributors. Generally, such giants like Walmart make it mandatory for their suppliers to trade via EDI with them to make it easy and consistent to process and keep track of the products being supplied from all over the world and of course pay in time to all of them.
