on demand merch is a shortened version of “print on demand merchandise,” referring to various types of products (beyond just apparel) that can be created and sold using the “print on demand” business model. This includes items like mugs, posters, phone cases, tote bags, and home decor. “On demand merch” allows creators and businesses to offer a wide range of custom-designed products without the need for bulk ordering or inventory management. When a customer purchases “on demand merch,” the order is sent to a “print on demand” service provider who prints the design on the product and ships it directly to the customer. This model is popular for its low risk and flexibility in offering diverse product lines.
