Job ID: 35068727

Budget: $10 – $20 USD

Dear All,
I need advice about costs of system for central management for sells.

Lets assume have a few fronend systems like online shop (selling products with subscriptions, payments etc, ebay, amazon, alibaba, normal f2f sell (offline)) and would like to manage all these sells in one place. So all data should be sync from these front ends system to my central management tool where I can manage subscriptions, delivery, business partners for delivery, todo list , charts etc.

Is there anything like this on the system where I can connect mentioned systems aboves without any development?
