AMazon INtegrationn

Hello All,  We are looking to purchase accounting software to track out Banking Information as well as Open Orders and Inventory from various E-Commerce Platforms.  Basically I would like to be able to launch the software at any time and see how much I have available on My Business Checking Account, My Available Funds on my Amazon Account, preferably also on unshipped items ( nice to have) and how much I have in my inventory. I understand there might not be a product to capture all of this but looking for your recommendations to get me as close as possible to what I need   thank you in advance
