This is an outstanding plugin. A real must-have for every Woocommerce store out there... There are so much crucial functionality offered here. I would recommend it to anyone, any day! You can easily calculate profit margin per product, check profit margin per month, per year, per ORDER, and much, much more. The functions Cost & Reports offers are crucial to understanding the health of your store, based on your costs vs. profit-margins. It even lets you see what profit your remaining stock will give you once it's sold (at the price you have set) The default Woocommerce reporting with fancy graphs are not easy to read, and it lacks too much information. This plugin fixes that. Sooo much easier to see actual numbers, instead of spending time trying to understand your graphs. The way the sheets work are genious. No matter what field you edit, the other fields related to that field will change. So if you want to calculate a new price based on a 150% margin, your new regular-price will show automatically. And all you have to do is press SAVE at the bottom. It's now done for all products! Perfect! If you instead want to insert your own prices for each product, the sheet will automatically calculate your margin. And the way the sheets are layed out, it becomes extremely easy to see where you should increase your prices. Also there are a separate report part of the plugin, where you can get simple and excel ready csv's for accounting. The developers are friendly, and very responsive - superb support! Thanks for an awesome plugin!
