At present, the demand of the terminal purchaser of industrial products is collection, but in reality, most of the hardware mechanical and Electrical Purchaser's quotation experience is fragmented. From different hardware mechanical and electrical distribution shop to purchase hundreds of materials, hundreds of standard parts non-standard parts, often need to spend two or three months or even more than half a year. In order to solve the pain point of industrial goods buyers, hardware mechanical and electrical industry retail model has evolved. First is the traditional hypermarket model, with Zhejiang Yongkang China Science and technology hardware city, Chengdu Wanguan hardware electromechanical and so on as representatives of hypermarket, gathering all kinds of merchants in the industrial chain, to help buyers better buy the industrial hardware production needs of mechanical and electrical products. But these vendors'products are not digitally distilled, and buyers still spend a lot of time buying what they need. Second is the entry of B2b, B2C and O2o, began to try to use data to build a burst of money to help buyers choose. "online hardware, physical store purchase" to a certain extent to save time costs, but in its offline physical store still can not buy all hardware electromechanical products, the customer's shopping experience is still fragmented. At present, tens of thousands of small B building materials dealers are developing their cloud alliances by taking advantage of the supply chain integration and internet sales tools enabled by s platform, will trade companies, hardware and electrical stores into their own "Sphere of influence" , to complete the customer's one-stop packing needs.
