Print-on-demand merchandising is a business model that allows individuals to create and sell custom products, such as apparel, accessories, and home goods, without maintaining inventory. When a customer places an order, a third-party printing service produces and ships the item directly to the customer. This approach reduces financial risk since you don't need to invest in bulk inventory or production costs upfront. It's an ideal option for artists and designers to showcase their creativity and monetize their work, using platforms like Printful, Redbubble, or Teespring to simplify the process of creating an online store.
