Rulefy is a rules engine that lets you control cart validation, automatic discounts, and payment method visibility from one dashboard. You define conditions using customer tags, cart totals, product collections, shipping addresses, and time windows. Rules run directly at checkout with no theme code changes needed.

• Control who can check out using rules you define in minutes
• Discounts apply automatically — no codes needed for customers
• Hide or show payment methods for specific customer groups
• One dashboard replaces separate validation and discount apps
• Pre-built templates so you don't start from scratch
