Updating Product COGS
If you're using Metorik's Cost of Goods / Profit Reports, you may find yourself wanting to update the COGS of existing products and orders.
To do so, first change the COGS of each product/variation in WooCommerce.
If you want to update the COGS of previous existing orders to use the new product/variation COGS, you need to run the Apply Costs to Previous Orders tool that can be found in the WooCommerce Settings under Products.
After updating all of your past orders, you can use the tool in your store's connection settings to reimport orders and bring in the new COGS:
Normally we keep your orders synced with your store automatically, but in this case, the COGS plugin does not tell us the previous orders have been updated, so we need to do it manually.
