Create a multi-channel sales dashboard

We need a simple multi-channel sales dashboard, taking sales data from our Opencart eCommerce store, Amazon, eBay, Rakuten & Etsy, so that we can quickly see our sales across all of our platforms. We will need to see sales for individual products also. The dashboard will need to be accessible from mobile and desktop on the web (we can host). We also need for this to be very clear, so that different members of our team who have less web knowledge can view this and understand it. We will need sales graphs for daily sales, weekly & monthly. We will want a comparison option on this also. It should be similar in visual look to the sales dashboard in WooCommerce, as it is very simple to navigate and understand.
