Open the product in Seller Dashboard → Products. For a Simple product, enable Manage stock quantity when you want Light Ideas to track a numeric quantity, then enter the available stock. You can also set the stock status to In stock, Out of stock or On backorder.

Variable products can manage stock separately for each variation, so different colours, finishes or sizes can have their own quantity and stock status.

Keep stock information current so customers are not offered products or variations that are no longer available.
