Sellercenter system extend OpenCart functionality to allow store owners to manage each product associated to a third party vendors/sellers information, turning Opencart from a simple retail store to a Multi-vendors/Sellers marketplace. This is especially useful for drop-shipping to keep track of the store operations.
Store Owner can assign different commission level associated to each vendor, the vendor would be charged by store owner whenever there is a successful transactions.
Store owners can accumulate all sales orders for each vendor and payout to vendors every month through PayPal, or Bank transfer.
Vendors/Sellers are able to login and create sub-users to manage their product listings, sales, etc.. with different access permissions, they would be totally independent in terms of managing their products and sales etc..
SellerCenter uses Opencart database only with some tables extra for the tool to work, it works independently in interaction with Opencart.
