OrderRules is a capacity management and checkout control app built specifically for Shopify merchants that need automated ways to manage order volume, fulfillment limits, and purchasing restrictions. The platform helps businesses such as bakeries, restaurants, florists, meal prep companies, and handmade goods sellers prevent overselling by enforcing configurable rules directly within Shopify checkout. Merchants can automate store opening and closing hours, set daily or weekly order caps, create per-product and collection-based limits, and restrict how many items or orders customers can purchase within specified timeframes. OrderRules also supports customer-specific purchase controls designed to prevent hoarding, scalping, and abuse by enforcing strict login validation and checkout restrictions. The platform operates using native Shopify Functions and checkout validation extensions, making it compatible with Shopify Plus, Online Store 2.0 themes, and headless storefronts without requiring custom development work. Businesses can monitor real-time capacity through analytics dashboards that include order charts, blocked-order reporting, and historical performance insights. Email notifications alert merchants when capacity thresholds are approaching or fully reached, helping operators stay informed without manually monitoring store activity. OrderRules is designed to automate repetitive operational tasks so merchants can focus on production, fulfillment, and customer service instead of manually closing stores or issuing refunds. By combining automated checkout enforcement, flexible capacity controls, and real-time analytics, OrderRules helps Shopify businesses improve operational efficiency and protect fulfillment capacity.
