Hi, Basically we provide some service to customers and they pay. This is online platform(real time). so looking for experienced, real time platforms developed already like OLA/Uber/Online shopping/Olx/ where users are selecting and buying something and they pay for it. And on other side sellers get intimation about that product enquiry. who ever bids best, they will get chance. And there will be website portal where orders will be there and suppliers will be there. Great platform. so please someone who really developed ecommerce will be ideal. This is online shopping, buyers tracking, sellers tracking ,products, menu, nice website showing what are the orders, what is the bidding, and who sold it, summary of report of categories, menu of goods, payment gateway integration etc.
