Software para administración MarketPlace

I seeks to develop a software in the cloud, for inventory management, orders and shipments of orders that are received through different online sales platforms like Amazon MarketPlace , Magento . MercadoLibre and the like. This includes integrating the platform with DHL, FedEx and Estafeta to guide each order is generated also follow up on the scan codes . A system of multiple users where each user has different privileges is sought. I want a system where I can go online and see all the sales/orders from all the channels (like amazon, ebay, my own site, etc.) and lets me see the inventory for everything in one place. I also want to manage the oders in one place, and for it to be integrated with different shipping companies so that I can generate shipping labels for each with this software. I also want to have differeent users, and each user has different privileges and they can manage different access to areas based on their privileges. I also want to integrate the software with invoicing, electronically and every invoice needs to connect our governments system. This already exists you just need to integrate into one of the invoicing systems that does this already. Prefer is the person is located in Mexico, agentina, spain, or columbia and speaks Spanish. ------------------------------------------------------------------------------------------ Se busca desarrollar un software en la nube, para manejo de inventarios, órdenes y envíos de ordenes que se reciben a través de diferentes plataformas de venta online, como Amazon MarketPlace, Magento.
