SimplePrint is a California-based print-on-demand partner with a Shopify app and direct Etsy / WooCommerce / BigCommerce integrations (API available). They focus on quick, no-inventory fulfillment for apparel, hats, bags/pet products, mugs & other hardgoods, with an in-house “SoftTouch DTF” method, sublimation for drinkware/hardgoods, and white-label shipping.
SimplePrint produces each item after the order is placed and ships it directly to your customer under your brand (white-label). You create products in their app, publish to your store, and SimplePrint handles printing, packing, and shipping from California, USA—so you can sell without holding inventory.
Free to install; you pay the base product + shipping per order. Their site positions POD as fast production (no inventory required). Publish customer-facing delivery as production + transit by region, and always order samples of hero SKUs to validate color, fabric/finish, and margins.
Tip: Start with one DTF tee, one hoodie, and one mug. Add size/care notes and publish region-specific delivery ranges to reduce returns.
