YITH Cost of Goods for WooCommerce allows you to check easily and quickly the real profit margin on the sale of your products.
The integration with YITH Multi Vendor allows you to control how to calculate the vendors’ commissions when the product has a cost set and choose whether to include the cost of the product in the commission or not.
To set up this to your own convenience, just make sure both premium plugins are installed and activated, then go to YITH > Multi Vendor > Commissions and you will be able to activate the following options:
YITH Cost of Goods handling: enable this to include the cost of goods in the commission calculations, disable it if you want to calculate the commissions only out of the product profit.
Show YITH Cost of Goods Information: enable this option to show whether the commission includes the product cost or not also in the commission details.
