The Custom store is a non-integrated store just for you to test how to create products and save them for future orders or move them to your e-commerce store for which we offer direct integrations (Shopify, Etsy, Woocomerce, Squarespace, Wix, BigCommerce).
You can save your product designs to your custom store so you can easily add them to future orders without the need to redesign them again.
