TeePopUp is a storefront builder for home t-shirt businesses, custom print shops, and pop up sellers. Sellers get their own storefront link to share with their existing customers. Customers can browse products, upload design files, and place orders. Payments are handled directly between sellers and customers via Zelle, Cash App, Venmo, or PayPal — TeePopUp does not process any payments. Sellers manage products, orders, and store appearance from a simple dashboard with 6 customizable themes.
