Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCustomezo is built for print shops, apparel brands, and print-on-demand sellers. Embed customizer sits on your product page: customers add text, upload logos, pick fonts and colors, preview, and add to cart. Built-in AI tools remove backgrounds, upscale low-res logos, and vectorize graphics. Set up multi-side print areas for front, back, and sleeves, and offer bulk orders with quantity discounts.
Theia turns any product into a personalized, print-ready product. Customers design directly on the product page — typing text, uploading images or sending print files — while you define the exact print area. Add custom options like dropdowns, swatches and date pickers, support front and back designs with color variant mockups, and download the original full-quality files from every order.
