E-Commerce website with separate signups for Buyer and Seller

I am leveraging on Django Oscar to build an E-Commerce website. The website should have separate signups for Buyer and Seller, and integrate with Paystack payment gateway to accept payments from customers. Since the website will have different shops(sellers) with buyers buying from any of the shops, payments and charges should have information about which shop a buyer is buying from, so as to know how much a shop has sold, this is to help the platform to know the right amount to pay to a shop in a Month.
