HBN: Quantity Limits

HBN: Quantity Limits lets you sell by case, require a minimum order, or stop shoppers from buying more than you allow. Set minimum, maximum, or required-multiple rules for products, variants, collections, or the whole catalog. Shoppers see clear guidance on product and cart pages, while Shopify validates enabled rules during checkout. Additional controls include retail and B2B conditions, scheduling, conflict checks, localized messages, and a rule simulator.
