Printify

Printify is a print-on-demand (POD) platform built since 2015 by the company of the same name and used by millions of people worldwide. It is meant for anyone who wants to sell their own merch or custom-printed goods but does not want to deal with inventory, production, or packing parcels. It suits beginners, content creators, and smaller online stores.

It works simply: you upload your design, pick a product from the catalog (t-shirt, mug, hoodie, poster, and hundreds more), and Printify instantly shows you how the finished item will look. When someone buys, the order goes to the nearest partner print shop, which prints the product and ships it straight to the customer. You only pay the production cost and the difference against your selling price is your profit.
