First of all, as the name suggests, print on demand is production per order basis, which means you only pay for the production cost of the products that you order to be produced once you receive an order from your customer. Put simply, you can use our design tool to upload your artwork that you are willing to sell on any product of your liking from our catalog and see a product preview, then market these products on your own channels, for example your e-commerce website or social media pages.
