While WordPress and WooCommerce provided the base, nearly everything here was custom, from the PHP-driven decal parser, to the discount engine, to the frontend preview canvas. The upload area uses a blend of JavaScript canvas rendering and server-side shape mapping to ensure artwork is print-ready and priced fairly.
This is a true example of WooCommerce being pushed beyond its typical use case, functioning more like a quoting tool than a traditional product listing. As the business scales, the backend logic makes growth more automated, while the user experience stays friction-free.
