PromoSync connects your Shopify store to PromoStandards suppliers, including SanMar, S&S Activewear, and PCNA, and imports their products, variants, images, and specs. It builds quantity tier pricing, enforces minimum advertised prices, and updates inventory on a schedule you choose. Decoration methods, imprint locations, setup fees, and run charges are added to products so customers can configure orders. You can also convert Shopify orders into supplier purchase orders from your admin.
