OpenCart E-shop Connect with Winera ERP

*READ EVERYTHING CLEARLY* i would like to connect my eshop, created in platform OPENCART, with my Winera ERP (based on MS SQL). more specifically, i want automatically every x period or every day at xx:xx am/pm, or manually with a button from my opencart administrator panel, to: 1) Sync Material (from erp to eshop) 2) Sync items on hand (stock) (from erp to eshop) 3) Sync Customers (from eshop to erp) 4) Send to the ERP new orders (from eshop to erp) For sync material action, i want to have the ability to choose to sync materials with image (on the ERP) or materials with specific category. For anything above, we already know which fields should be sync with the eshop.
