Spiff 3D Product Customization is an innovative app that empowers both online and in-store merchants to offer personalized products while keeping production costs low and prices affordable for consumers. By leveraging the four foundational pillars—Asset Storage, Product Customizer, Data Processing, and Delivery Automation—Spiff facilitates the creation of a vast array of customization experiences. Merchants can opt for the intuitive, pre-configured user interface or utilize the flexible API for crafting bespoke UI/UX tailored to specific needs. The app also allows for storing rich data on each product variant, enabling informed downstream use. Furthermore, customizable themes provide merchants with options to either select from existing designs or create their own. Additionally, the product sharing feature helps merchants tap into traffic from partner stores, enhancing visibility and engagement.
