Seedshirt is an online platform that helps individuals, creators, groups and organizations design and sell custom printed products. Users can launch a campaign to offer designs directly to their communities or create a white-label shop for a brand, club or band. Shops can be customized with options such as an adjusted storefront and an About page.

The platform supports a range of purposes, including fundraising, band and influencer merchandise, group apparel, and sales by designers building their own small labels. Products include T-shirts, hoodies and other printed items. Sellers can set their earnings, while Seedshirt handles production, order and shipping administration, and customer service. The service is described as free for sellers, with costs covered by customer orders.

Seedshirt says its products are printed in Germany using modern printing equipment, with orders produced individually or in larger quantities. Production typically takes one to five working days before items are shipped directly to customers.
