Customization Cost is a hidden line-item that attaches a personalization charge to customer orders when option configurations trigger customization. It is not a standalone product and does not appear as a catalog item; instead, the fee is captured and added to the order total through the option-driven workflow. This approach ensures precise invoicing for personalized services without introducing separate catalog entries.
