Print on Demand (P.O.D.) companies help businesses who want to extend their product offerings further but don't have the equipment or know-how to create certain products. An example of this would be a graphic designer who wants to sell their designs on t-shirts, but they don't have the equipment to do this themselves. A P.O.D. company can help with this! Most companies integrate with Etsy, Shopify, WooCommerce, and more.
