Create automatic/Semi automatic orders fulfillment panel for my amazon stores.

I would like to create a panel that will be connected to my Amazon stores by API I currently have different stores all over the world. The stores I currently have : [login to view URL] [login to view URL] [login to view URL] [login to view URL] I'm planning to expand even further, And I want that this panel will work with any Amazon (buyer site) and eBay (buyer site) How should it work practically? I will be able to add SKU of a product (that I currently selling) and I will attach it to a link. This link is the "buying" link to my supplier. My supplier can be [login to view URL] or [login to view URL] The panel will also get the current selling price of the relevant product through the API. We will be able to put a specific range of the buying price of the supplier. For example : This is SKU of a product that I'm selling on [login to view URL] : 39O-U88-HD4 And this is my supplier Link on [login to view URL] and the total price is 15.64 EURO : [login to view URL] The panel will automatically detect my selling price, That its 41.00 EURO : [login to view URL] So you should create a term for the panel. Let's say I add this product to the panel, And I'm telling it that if the total price includes shipping and taxes (supplier price - [login to view URL]) is higher than 16 euro Then - DO NOT FULFILL THE ORDER. - Notify me by email/message that the order was not fulfilled due to a higher price than what was defined. IF not, Fulfill the order. The panel will gather the shipping information of our customers, and he will add it automatically to the order. the panel will be able to detect all the orders that attached to the SKU 39O-U88-HD4 and it will know that this specific SKU needs to be fulfilled with specific shipping addresses of customers. It will also detect the quantity that was ordered from us, and it will fit the quantity in the amount that we buy from our supplier. The panel will be able to calculate our profit for each and every order due to our mathematic terms. He will be able to detect the price of the supplier that we paid, And the selling price of the product. What happened once the panel will make an order? The panel will save this information : *Date And hour of the order *Product name + supplier Link * The Order id we get as sellers * The order id we get as buyers *Profit (due to our mathematical terms) *Paypal use or credit card use (only on eBay suppliers) *Total amount paid for the order. And the panel will mark the order as shipped as soon as it finishes to fulfill. The bot can be Automatic/ Semi-automatic. We prefer it will be fully automatic. Here is an example of similar software : [login to view URL] You can get direction and ideas through this similar software, for creating this panel.
