On-Demand manufacturing is a production model when Designers make garments after customers place an order. In the fashion industry, this is also called made-to-order. Brands do not send the order quantities they need to their manufacturers until their customers have ordered the garments. On-Demand manufacturing generally requires paying for the item up-front. This process can lead to longer wait times for the customers. However, with digital printing and streamlined manufacturing, factories can help Designers shorten lead times dramatically and not produce items that may never sell.
