Managing Total Sale by Supplier

Hi, I am managing a website where I am selling about 200+ products. Those products are belong to different Suppliers. I have Supplier Management for Woocommerce installed, but with this, I can just connect a specific product to a supplier (that is fine…) or set up the supplier product price. But at the end, when I need to figured out how much I need to pay to each supplier (I do this every 3 months) there is no way to get a report for each one… They are providing me a stock and I will pay them what I am selling from that stock every 3 months… Anyone knows how to manage this side of the business?
