Rulio: Cart & Checkout Rules

Rulio helps you create and enforce smart order rules for your Shopify store with real validation at cart and checkout. Set minimum and maximum limits for order quantity, cart total, and product weight across individual products, variants, or entire collections. The app combines real-time cart warnings with Shopify Functions checkout validation, making sure customers can't bypass your rules. Schedule rules with specific start and end dates, perfect for promotions or seasonal requirements. B2B stores benefit from tailored order limits, while multi-language error messages keep communication clear for international customers. All rules are enforced automatically, preventing orders that don't meet your requirements from going through checkout.
