Order Cap stops overselling for capacity-limited shops. Set a limit on any product or variant. Once it hits zero, checkout is blocked and customers see a sold-out badge. No cancellation emails, no manual inventory work. Choose daily reset at a time and timezone you pick, or lifetime mode you reset yourself. Badges appear on product pages, collection grids, and cart line items when spots run low. Multiple styles with custom messages. Checkout validation blocks orders before payment.
