About this plugin
KossLabs Cart Limits is a modern, ultra-lightweight order limits engine engineered specifically for modern WooCommerce stores. It is built from the ground up to support the new React-based Cart & Checkout Blocks, the official WooCommerce Store API, and High-Performance Order Storage ( HPOS ).
Whether you run a B2B wholesale store requiring minimum purchase thresholds or a retail store preventing unprofitable micro-orders, KossLabs Cart Limits provides frictionless limits without slowing down your website.
🚀 Key Technical Differentiators
- Dual-Engine Validation (Store API + Classic): Complete protection across traditional checkout and modern Gutenberg React Cart/Checkout blocks ( /wp-json/wc/store/v1/cart ). Customers cannot bypass rules by switching checkout layouts.
- Smart Difference Engine (CRO-Driven Notices): Instead of cold, frustrating error messages, CartRules displays encouraging, conversion-focused notices with real-time mathematical calculations:
- {min_amount}, {current_amount}, {needed_amount} (exact missing money to checkout)
- {min_qty}, {current_qty}, {needed_qty} (remaining quantity needed)
- {product_title}, {max_qty}, {excess_qty}
- Intelligent Stock Management (Allow Remaining Stock): If your remaining stock is lower than your minimum order threshold (e.g. 2 units left in stock but minimum is 5), CartRules automatically adjusts the threshold so your last inventory does not get stranded unsold.
- Auto-Bump Loop Integration: When customers click “Add to Cart” directly from archive/shop loops, the system automatically adds the minimum required quantity instead of locking them in an error loop.
- Zero-Bloat & HPOS Native: Zero custom SQL database tables. Zero jQuery dependency (< 3 KB pure Vanilla JS). Full Redis, Varnish, and LiteSpeed cache compatibility.
