If you are migrating from WooCommerce Cost of Goods, you will be able to import all the costs you’ve previously set up. This way, you don’t have to add the costs again on each of your products and the migration will be as easy as clicking on a button.
In fact, you just have to keep both plugins activated, go to YITH Plugins > Cost of Goods> Settings and click on the button Import Costs.
Note: This option is only visible if the WooCommerce Cost of Goods plugin is activated.
