Unrelated to my previous issues (which you are, or have, addressed), there is a request that would make this plugin 5 stars for us….
Can you add the order profit to the “orders export” that is native to Woocommerce? This way we can easily report on profits. Without this, the profit numbers are anecdotal as we can just “look” at the orders tab to see “about” what we are making, but no way to really report on it.
Not sure if I understood you correctly, but if you go to “WooCommerce > Reports > Orders > Cost of goods”, you will be able to see the profit and costs report. And if you click “Export CSV” there, you will get profit and costs data in the CSV file. Is that what you need?
